Microsoft Lists for Android

With this new app, your users will now be able to access their Microsoft Lists (including SharePoint lists) on the go anytime, anywhere by using Microsoft Lists for Android.

With Lists, you can manage events, track issues and assets, help with new-employee onboarding, and keep coordinated across inventory. With access on the go, easy sharing and quick photo capture, you can keep everyone connected with the latest information using Microsoft Lists.

Note: The app is currently available to members of an organization that has an Office 365 or Microsoft 365 commercial subscription that includes SharePoint. You sign in with your OrgID (Azure Active Directory credentials).

Download the apphere.

This message is associated with Microsoft 365 Roadmap ID 70704

When this will happen

We will begin rolling this out in late April and expect to complete rollout in early May.

How this will affect your organization

Users will be able to download Microsoft Lists for Android from the Google Play Store.

With the Lists app, the user can:

  • Create new lists easily via ready-made templates
  • Get to lists—including lists they’ve already been using–from the Recent, My lists, and Favorites sections or via Search
  • View lists, even when offline

What you need to do to prepare


Adding Microsoft Lists for Android as a Target app:The Microsoft Lists app will be added to the Intune console in May. You can target it today by selecting ‘Selected apps’ in the ‘Target policy to’ dropdown box. Click ‘Select custom apps’ to target based on Microsoft Lists ‘Package ID’ – com.microsoft.lists.public

Validating the Conditional Access policy:
If you are using a Conditional Access policy that only leverages “Require app protection policy” (App Protection Policy (APP), also known as MAM), or leverages APP as a part of one of the selected controls, then no further action may be needed from your end.

Please note that the Lists Android app currently doesn’t support ‘Require approved client app’ grant access. Only ‘Require app protection policy’ is supported and recommended since it provides higher level of assurance. However, in late May, Lists Android will also support the Conditional Access (CA) grant access control, ‘Require approved client app’, like other Microsoft 365 apps, such as SharePoint.

You can also utilize “Require one of the selected controls” under grant controls that acts as an OR clause. This is used within policy to enable users to utilize apps that support either the “Require app protection policy or Require approved client app grant controls. If you are not utilizing APP, CA, or either grant access control, then no action is needed.

For more details on how to target apps with your app protection policy and configure conditional access, see

You might want to notify your users about this new app and update your training and documentation as appropriate.

Note: Microsoft Lists for Android does not yet enable people to sign in with their Microsoft Account (reference the Microsoft Lists – MSA Preview).

OneDrive sync app will automatically configure accounts

This release will enable the OneDrive sync app to sign into an account even quicker. Users will experience an improved single sign-on experience by automatically being able to see their OneDrive files within their file browser upon sign in or OneDrive app update.

  • On Windows, users who are signed into the device with an Azure Active Directory (AAD) account will see their OneDrive folder start syncing without entering their account credentials.
  • On macOS, users who are signed into another Microsoft app (i.e., Office, Teams, Edge, etc.) will see their OneDrive folder start syncing without entering their account credentials.

This message is associated with Microsoft 365 Roadmap ID 93242.

When this will happen:

We will begin rolling out in mid-June and expect to complete by late July.

How this will affect your organization:

If OneDrive is running in the background, it will periodically try to sign in with an existing AAD credential that is made available to Microsoft applications. This new capability will replace our existing Windows policy of SilentAccountConfig and is brand new for macOS. If you previously had SilentAccountConfig enabled, then you will see no difference in behavior. If you have never enabled this policy, then as long as OneDrive is configured to run in the background, you will have a more streamlined experience onboarding to OneDrive.

What you need to do to prepare:

Ensure that your OneDrive is set up to run in the background. On macOS you can confirm this by setting the “OpenAtLogin” plist. OneDrive already runs in the background on Windows.

If you would like to disable this, then there is a new policy and plist item in build 22.065 called “DisableAutoConfig”. If you set this to 1, it will disable this new automatic account configuration.

Suggested Replies in Teams Desktop

Suggested Replies present users with an option of three responses to choose from for selected messages and is now available to your users in Teams Desktop.

We apologize for not informing you about this change prior to it being released. We continue to work to ensure we are being proactive in our communications. Thank you for your patience.

When this will happen:

  • Standard: Complete
  • GCC: mid-May through early June
  • GCC-High: early June through late June
  • DoD: early July through late July

How this will affect your organization:

Once available, users will be able to quickly reply to a given message by tapping on a suggested reply.

Custom organization branding for quarantine notification (custom sender address and Custom subject)

We will be adding capabilities to making it possible for Security Operations (SecOps) to customize end user quarantine notifications with their respective organization sender address and custom subject.

This message is associated with Microsoft 365 Roadmap ID 93301.

When this will happen:

Standard: will begin rolling out in late July and is expected to be complete by early August.

Government: will begin rolling out in early August and is expected to be complete by mid-August.

How this will affect your organization:

This change will enable admins to customize the sender address of the quarantine notification as well as the subject of the notification.

Customize sender address

OneDrive and SharePoint: Improved Move/Copy user experience

We’re refreshing the Move/Copy user experience in OneDrive and SharePoint to make it easier for you to move and copy your files and folders.

This message is associated with Microsoft 365 Roadmap ID 85567

When this will happen:

We will gradually roll out starting with Targeted release in mid-October and complete for Standard release in mid-November.

How this will affect your organization:

When a user moves or copies a file or folder within OneDrive or SharePoint, they will see a new dialog-based experience to choose the destination for their content. There is no change to the underlying Move or Copy capabilities—all limitations, errors and admin settings will be unimpacted.

Move Copy Experience
View image in new tab

What you need to do to prepare:

You might want to notify your OneDrive and SharePoint end users, update your user training, and prepare your help desk.

For your users: The support article titled Move or copy files in SharePoint describes the limitations and current Move experience. The screenshots will be updated to reflect the new experience as it’s rolling out to customers.

Microsoft Forms new App “Polls” in Teams

Microsoft Forms has always focused on providing the best polling experience to our customers. However, according to customer feedback and telemetry, we have determined that many people don’t know the “Forms” App provides polling capability in Teams.

To provide a better experience we are delivering a new Teams app specifically for polling capabilities. This new app will be discoverable in Teams meetings/chats as “Polls”.

This message is associated with Microsoft 365 Roadmap ID 84567

When this will happen:

We will begin rolling this out starting in Teams meetings and then moving to Teams chat in mid-October and expect to complete by the end of November.

The original “Forms” app will be retired from Teams meetings in mid-November, and then will be retired from Teams chat in at the end of December. Once retired from meetings/chat the “Forms” app will only be available in the Teams channel tab to provide Survey capabilities.

How this will affect your organization

Once this rollout is complete:

  1. The new Microsoft Forms App “Polls” will have the same functionality, same service, and there will be no need for data migration.
  2. For the previous polls that were created in the original App “Forms”, these polls will not be lost. Poll owners can still view them in the new App “Polls” portal in Teams OR view it in the Forms web portal page (http://forms.office.com/)
  3. The original App “Forms” polling capability will be retired in Teams meeting and Teams chat. Original App “Forms” survey capability in Teams channel Tab is not impacted.

What you need to do to prepare

You may want to update your users on the upcoming changes. We will continue to update this post with additional information as we proceed.

HUGE MS Whiteboard Update

Available today


The following features are live today and are available on web, Teams and Android. The new Whiteboard will also be coming to Windows and iOS next month.


Fresh modern look and feel


When you open the new Whiteboard, you’ll notice a brand new user interface that combines a clean, modern look and feel with improved functionality. The new visual refresh makes features easier to access and to find. It’s also built to support the ever-growing capabilities of the app.


On desktops, laptops, and tablets, inking tools and content creation menus are separated to reduce cognitive load, while an app bar at the top of the canvas provides all of your collaboration and board-specific properties. On mobile, the creation panel & board controls are hidden to optimize real estate for viewing and collaboration. Large, colorful icons make it easy to use for mouse, touch, and pen users alike.

40+ new templates


We’re excited to announce a wide array of new Whiteboard templates! Expand and strengthen your whiteboard sessions with templates for common scenarios like brainstorming, agile rituals, problem solving, group projects and many more. We have added over 40 new, fully customizable templates to help people get started faster, generate flow, and design structure for their innovative ideas.

12 new sticky notes & note grids


Microsoft Whiteboard just got more colorful and organized, helping make your next workshop or brainstorming session more successful.


Sticky notes now offer more variety with an array of 12 colorful shades to choose from. Use different colors to create a color code system and get more organized by sorting by different color categories. Alternatively, assign one color per person to make it easier to see who contributed different ideas. Whatever your setup, enhance visual collaboration and encourage participation through the beauty of color.


Note grids help you create and build structure and form in your whiteboard session. Note grids present sticky notes in a clear and organized format. Customize each sticky note by color order and click to easily add extra sticky notes. You can also organize note grids by adding a title to them.

Expression is a cornerstone of collaboration. Users can now provide lightweight contextual feedback with a set of fun, engaging and meaningful reactions. Choose from a set of eight reactions to quickly communicate your thoughts and feelings on other’s ideas. Encourage participation from a broader range of participants. With reactions, it’s easy to engage and reply quickly in the moment!

							Welcome to the new Whiteboard!

Insert images


Images can help us learn, grab attention, and convey abstract and complex concepts. Bring your whiteboard session to life by adding photos and images to convey visual ideas more impactfully. Users can download and insert images onto the canvas with the insert image feature.

Flowcharts and diagrams play important roles in describing processes and in organizing information. Use shapes to quickly start a flowchart or to create your own diagram. Basic shapes, lines and arrows can now be added with the click of a mouse or the tap of a finger. Once added, you can resize, rotate and recolor the shape fill and border.

New inking tools


thumbnail image 7 of blog post titled 

							Welcome to the new Whiteboard!


Digital ink is an important part of Whiteboard, whether used to express your own ideas or to comment and annotate on other’s ideas. Whiteboard is empowering everyone to leverage the unique visual expression capabilities that ink can offer.


Whiteboard now has 15 new pen and highlighter color options and a range of thicknesses to help visualize your content and bring your ideas to life. In addition to the traditional colors, spark the imagination and creativity of your team with Rainbow and Galaxy ink!


Ink Arrows


With ink arrows, get right to the point! Add the arrow attribute to any pen so your arrows look perfect every time.


This feature adds a single or double arrowhead to the end of your ink stroke automatically, making inking easier and keeping your diagrams and annotations clean and organized.

Ink straight lines


Drawing straight lines feels impossible! But not anymore…just press the Shift key as you draw. That’s it.


By holding down the Shift key and drawing, you’ll automatically create a straight line between the starting point of your stroke and your cursor. You can continue to move your cursor, finger, or pen to adjust the length and angle of your line.


Your line will automatically snap to 0, 45, and 90 degrees and to the nearest stroke end. If you need a little more flexibility, you can release the Shift key. This disables the snapping behavior and lets you adjust your line to anywhere you need it on the screen. This feature works for arrow strokes too, making it easy to create straight ink arrows!

Ink to shape intelligence


Shapes are a building block for expression in visual collaboration. Create and iterate in a smooth and seamless way with ink to shape recognition. This feature allows users to visualize and conceptualize by quickly drawing shapes and then watch them automatically straighten! The best part? Converted ink is still ink, so it’s erasable, just like your other ink strokes.


Ink shapes with mouse:


Now inking shapes with mouse is easy! With this setting on, all the ink shapes you draw with a mouse will be automatically converted. If you prefer your original ink, just undo and you’ll see your original ink stroke. Not drawing many shapes? You can turn this setting off too.


Ink shapes with pen:


Draw and hold gesture shape conversion! Draw a line, circle, triangle, square, rectangle, rhombus, pentagon, or hexagon using a single ink stroke. Before picking your pen up off the screen, hold it in place for a few milliseconds. The shape will convert, and you can leave the ink as-is, or resize or rotate the converted shape!

Ink tools keyboard shortcuts


Your tools at your fingertips. Switch between ink tools seamlessly using keyboard shortcuts. Stay focused on your content without having to change focus to the toolbar.


Switch to Draw Mode Alt + W  / Alt + W + 1 
Pen 2 Alt + W + 2 
Pen 3 Alt + W + 3
Highlighter Alt + H 
Erase Alt + X
Arrow mode Alt + A
Double arrow Alt + Shift + A
Beautify Alt + B


Ink tactile signals with the Surface Slim Pen 2


When inking on the new Surface Pro 8 or Surface Studio laptop running Windows 11, with the new Surface Slim Pen 2, you can now feel slight vibrations that make writing and drawing feel more realistic. Pens, highlighters, and laser pointers will all have a unique continuous vibration as you move your pen across the canvas, giving you a more natural inking experience.


In addition to a more natural inking feel while drawing, inking will feel more engaging with haptic signals for gestures. Now, when converting your ink, you’ll feel a short vibration telling you that the ink has been successfully converted, giving you more confidence as you ink.


Format background


Who said whiteboards can only be white? Customize your board by changing the background color and pattern with attractive colors and grid designs to suit your needs. Leverage black to create a “dark mode” for your next project.

Object alignment and rotation snapping


Arrange your content seamlessly with alignment, snapping, and rotation. As you drag one canvas object towards another, alignment guides appear to help you place your item precisely in line with the objects around it. As you rotate an object, watch it snap to 0, 45, and 90 degrees to help you achieve the exact rotation you need.

Bring to Front and Send to Back


Optimally reposition objects that are on the whiteboard canvas by re-arranging and layering them with the Bring to Front and Send to Back feature.

Coming next month


We’re continuously refreshing and updating Whiteboard based on feedback and customer needs. Here is a sneak peek into some of the new features that will be rolling out next month.


New Whiteboard for Windows and iOS


The new Whiteboard provides a single unified user experience for all our customers across all devices, operating systems, and platforms. We’re rolling out an update to our native apps on Windows and iOS. This update will happen automatically and will provide you with all the new Whiteboard features from templates, shapes and reactions, to inking improvements, and more.

							Welcome to the new Whiteboard!


Expanded support for consumer accounts


Furthering our goal of making Whiteboard available and accessible to everyone, we will soon support Microsoft accounts in our Android app and on the web in addition to our existing support in Windows and iOS apps. This expands Whiteboard’s availability for everyone across all the devices they use regularly-both at work and home.


Insert documents


The ability to organize and bring in rich content is a key part of the new Whiteboard experience. Next month you can bring in documents, such as PowerPoint presentations to annotate on, make connections, and iterate together.


thumbnail image 12 of blog post titled 

							Welcome to the new Whiteboard!

Coming in the next few months


Whiteboard is being rebuilt on top of OneDrive for Business to integrate seamlessly across the Microsoft 365 suite, so you can create, share, discover, and manage whiteboards as easily as any Office document. Availability for commercial customers has been shared through Message Center, and OneDrive for Business storage will become the default for new whiteboards in early 2022. As part of this change, we will be enabling many new capabilities outlined below.


Collaborative cursors


Hop on a whiteboard with several other colleagues and watch the board come alive. Collaborative cursors let you see other people on the board and what they’re working on in real time. Each user will be represented by a different color and a name bubble. Use collaborative cursors to guide each other on the board and follow along as your colleagues are explaining.


Girl in a jacket


Collaboration roster


The new collaboration roster shows you who’s actively collaborating on the whiteboard in real time with you. If no one’s in the whiteboard, it will show you who made the last edit and when, making asynchronous hybrid work collaboration even easier.




The new share control for the web should feel familiar, as we’re using the same sharing dialog you’ll find in Office online and other experiences. This share control allows you to select specific people in your organization to share the link with, making it even easier to stay in the flow while working.


Laser pointer


Get other people’s attention as you share your best ideas. When you’re collaborating with others, you can turn your mouse into a laser pointer to draw attention to something in the board. The laser pointer ink will automatically animate away slowly, keeping you in your flow.

Office.com search and discovery


Get back to your whiteboards quickly by finding them in your recent list or searching for them on Office.com.


Recycle bin


When whiteboards are stored in OneDrive for Business, you will be able to find and recover deleted whiteboards in your recycle bin.


Note: The above-mentioned features are available today for any GCC customers who are using Whiteboard on OneDrive for Business. The timeframe that these features become available to commercial customers depends on when an organization opts-in to OneDrive for Business. Learn more here. 


We’re so excited to share these updates with you today and offer a sneak peek into what’s coming in the next few months. We hear from customers every day that while the future of work may be evolving, one thing remains clear—it’s never been more important for people to be able to collaborate effectively, wherever and whenever. We have reimagined the new Microsoft Whiteboard, the visual collaboration workspace in Microsoft 365, to do just that.

New Permissions management page in Microsoft 365 compliance center

You will soon see a new Permissions landing page within the Microsoft 365 compliance center from which admins will be able to view and assign user roles and create and modify custom role groups, activities currently managed within the legacy Office 365 Security & Compliance Center.

This message is associated with Microsoft 365 Roadmap ID 72239

When this will happen:

Rollout will begin in late May and is expected to be complete by the end of June.

How this will affect your organization:

Previously, admins needed to visit the legacy Security & Compliance Center to configure compliance center permissions (i.e. add a user to a role; create, delete, or modify custom role groups). With this update, admins will be able to complete permissions-related tasks directly within the Microsoft 365 compliance center.

From the new Permissions landing page, you can click on Azure AD roles to see which Azure roles are currently available for Microsoft 365 compliance center, and which users are assigned to what roles.

Clicking on Compliance center roles will allow you to create, modify, or delete roles in the same way that is possible within the legacy portal.
Azure AD Roles
View image in new tab

The legacy permissions experience will continue to be available until the Security & Compliance Center is retired. Admins are encouraged to transition to the new Microsoft 365 compliance center permissions workflow experience as soon as it becomes available for you.
Compliance Center Roles
View image in new tab

What you need to do to prepare:

To update permissions, you must be a global administrator or assigned the Role Management role (a role assigned only to the Organization Management role group).

You can access the new Permissions landing page by visiting the Microsoft 365 compliance center and selecting Permissions from the left navigation.

Migrate content from Dropbox to Microsoft 365

In public preview, this new feature release will enable admins to take advantage of our expanded support for third-party cloud providers and migrate content from Dropbox to Microsoft 365.

This message is associated with Microsoft 365 Roadmap ID 82015.

When this will happen:

We will begin rolling this out for Public Preview in late May and expect to complete the rollout by early June.

How this will affect your organization:

This release will enable you to migrate your Dropbox folders, files, and users to OneDrive, SharePoint, and Teams in Microsoft 365 and collaborate all in one place.

As you connect to a Dropbox for Business account, the service begins discovering users and their files. The service will automatically map to an individual’s OneDrive accounts, but you can also manually map to a specific OneDrive user account, SharePoint site, or a Teams channel.

If you want to migrate your content from Dropbox into Microsoft 365, you can use this tool to copy your content from Dropbox to Microsoft 365.

Note: To access, you must be a global admin or OneDrive/SharePoint admin to the Microsoft 365 tenant where you want to migrate your content.


This preview is currently supporting small to medium Dropbox accounts. For the large Dropbox accounts, some of the features may not function as expected. You can use Mover.io if the size of this Dropbox account exceeds the limit supported by this preview release.

Windows 10, version 21H1 now available

Windows 10, version 21H1 now available
Windows 10, version 21H1 (also referred to as the Windows 10 May 2021 Update) is scoped to deliver important features that improve security, remote access, and quality—and engineered to provide a fast update experience for those currently running Windows 10, version 2004 or 20H2.
When will this happen:
Windows 10, version 21H1 is available today through Windows Server Update Services (WSUS) and Windows Update for Business, and can be downloaded from Visual Studio Subscriptions, the Software Download Center (via Update Assistant or the Media Creation Tool), and the Volume Licensing Service Center.
For the end user, we are initially taking a measured seeker-based approach to the rollout of this update. We are throttling availability up over the coming weeks to ensure a reliable download experience for all, so the update may not be offered right away. Additionally, some devices might have a compatibility issue for which a safeguard hold is in place. In these cases, we will not offer the update until we are confident that the device will have a good update experience.
How this will affect your organization:
This feature is optional and new for IT administrators to consider using to help with targeting of policies and applications for users on specific devices. You’ll experience a new “Opt-in” capability for this feature in order to evaluate and experience this new functionality. Find out more by reviewing the content and details below.
What you need to do to prepare:
Just as we did for devices updating from Windows 10, version 2004 to version 20H2, we will be delivering Windows 10, version 21H1 via an enablement package to devices running version 2004 or version 20H2—resulting in a fast installation experience for users of those devices. For those updating to Windows 10, version 21H1 from Windows 10, version 1909 and earlier, the process will be similar to previous updates.
We recommend that you read How to get Windows 10, version 21H1 for information on our rollout strategy, then check out the updated and refreshed IT tools and resources (e.g. Security Baselines and ADMX) to support the deployment of this update across your device estate.
Additional information
The following resources have also been updated to help you continue to manage updates effectively in your organization:
  • Windows release health hub – The quickest way to stay up to date on update-related news, announcements, and best practices; important lifecycle reminders, and the status of known issues and safeguard holds.
  • Windows 10 release information – A list of current Windows 10 versions by servicing option along with release dates, build numbers, end of service dates, and release history.
  • Windows 10, version 21H1 update history – A list of all updates (monthly and out-of-band) released for Windows 10, version 21H1 sorted in reverse chronological order.

Prepare your SharePoint and OneDrive environment for end of support for Internet Explorer 11

As shared in MC220490 last year, Microsoft 365 apps and services will not support Internet Explorer 11 (IE 11) after August 17, 2021.

How this will affect your organization:

Once this change takes effect, Microsoft 365 apps and services, including SharePoint Online and OneDrive, will not be supported on IE 11. This means that after the above dates, customers will have a degraded experience or will be unable to connect to Microsoft 365 apps and services on IE 11. For degraded experiences, new Microsoft 365 features will not be available or certain features may cease to work when accessing the app or service via IE 11. While we know this change will be difficult for some customers, we believe that they will get the most out of Microsoft 365 apps when using the Microsoft Edge browser. Microsoft 365 users will be well served with this change through faster and more responsive web access to greater sets of features in everyday toolsets.

What you need to do to prepare:

As this date comes closer, we are committed to helping make this transition as smooth as possible for our customers and have identified considerations and practices for admins to help transition off classic SharePoint features that rely on Internet Explorer 11. If you use IE11 browsers to access SharePoint or OneDrive content, we strongly recommend you to review the guidelines posted in this article and take the necessary action before August 17, 2021 so there is no service disruption for users: Prepare your SharePoint and OneDrive for Business environment for the retirement of Internet Explorer 11.

Admins can monitor the IE11 browser usage for their tenants in Admin Center. Check this article to review your browser usage: Microsoft 365 Reports in the admin center – Microsoft browser usage – Microsoft 365 admin | Microsoft Docs

If your organization already finished upgrading to Microsoft Edge, no further action would be needed.
