[Introduction]

We’re updating how entities inserted from Add Work Content under the + menu behave in Microsoft 365 Copilot and Copilot Chat. With this change, entity names (such as document titles, people names, or other referenced objects) will no longer be inserted as text within the input box, making it easier for users to craft clean prompts without needing to manually delete entity labels. This feature is available to both users with a Microsoft 365 Copilot license (Microsoft 365 Copilot users) and users without a Microsoft 365 Copilot license (Copilot Chat users), but the experience varies.

This message is associated with Microsoft 365 Roadmap ID 552592.

Updated June 4, 2026: We have paused rollout of this feature at this time. We will communicate via Message center when we are ready to proceed. Thank you for your patience.

[Introduction]

The people card experience in Classic Outlook is simplifying. As part of this update, the people card expanded view in Classic Outlook will be retired. This change streamlines the experience and ensures consistency with other Office applications where only the standard contact card is available.

[When this will happen:]

• We will communicate via Message center when we are ready to proceed. 

[How this affects your organization:]

Who is affected:

• Users who use Classic Outlook and access the people card expanded view.

What will happen:

• The people card expanded view in Classic Outlook will be retired.



• Only the standard contact card view will be available in Classic Outlook.



• Users will continue to find the standard contact card when hovering over a recipient. This experience already exists in other Office applications and in some Outlook configurations today.
• Today, users can access the expanded view in Classic Outlook by right‑clicking an email recipient and selecting Open contact card, or by double‑clicking an email recipient. After retirement, these same actions will display the standard contact card instead.
• The standard contact card does not include the following features that were available in the expanded view:
• Local time
• “Works with” in the organization chart
• Change picture entry point (accessible from Outlook by selecting File, then clicking the Change link under your photo)
• Users who rely on these features can use Outlook on the web or New Outlook, which provide a richer people card experience.
• The expanded view being retired was not customizable. Any customizations made to the standard contact card will remain after this change.

[What you can do to prepare:]

• No admin action is required; this change will occur automatically.
• Notify users about the retirement of the people card expanded view in Classic Outlook.
• Update internal documentation or helpdesk guidance, if applicable.
• Encourage users who rely on features such as local time, works with, or changing profile pictures to use Outlook on the web or New Outlook.

Admins and users who want to familiarize themselves with the standard contact card experience can test it in Office apps where this change already exists. For example:

• Open Word and author some text.
• Save the file to OneDrive.
• Right-click text and select New comment.
• Add a comment, @mention yourself or another user, and select the mentioned name.
• Select Contact, Organization, or Membership to view the abbreviated people card.

[Introduction]

Microsoft is updating an existing sensitivity label setting that controls whether certain connected experiences can analyze file content. This change extends support of this label setting to additional platforms and extends coverage of the label setting to include all connected experiences that analyze content in Word, Excel, and PowerPoint, rather than a subset of these experiences.

[When this will happen]

• Public Preview: We will begin rolling out in mid-May 2026 and expect to complete by mid-June 2026 (previously late May).
• General Availability (Worldwide, GCC, GCC High, DoD): We will begin rolling out in mid-June 2026 (previously early June) and expect to complete by late June 2026.

[How this affects your organization]

Who is affected

• Organizations using Microsoft Purview sensitivity labels in Word, Excel, and PowerPoint
• Users opening files that have a sensitivity label configured with “Prevent some connected experiences that analyze content”

What will happen

• Files with this label setting will not be sent to any Microsoft connected experiences for content analysis.
• Previously, this label setting blocked only a subset of connected experiences; enforcement is now expanded in Word, Excel, and PowerPoint.
• This change applies automatically to existing labels configured with this setting.
• There is no change to label configuration, and the behavior is enforced by default once the feature rolls out.

[What you can do to prepare]

No action is required if your organization already uses sensitivity labels.

Optional recommended steps:

• Review sensitivity labels that use the “Prevent some connected experiences that analyze content” setting to confirm they align with your organization’s data handling expectations.
• Inform compliance and helpdesk teams that labeled files may no longer interact with connected experiences that analyze content in Word, Excel, and PowerPoint.
• Update internal documentation if you describe how sensitivity labels affect Office app functionality.

Updated June 3, 2026: We have updated the content and timeline. We are not proceeding with gov clouds at this time. We apologize for any inconvenience. 

[Introduction]

We’re fixing issues in the way OneDrive for Business applies user storage quotas to ensure they are consistently aligned with license entitlements and current product behavior. This change fixes an issue where user-specific storage limits could be incorrectly applied during quota refreshes, which could result in inaccurate storage enforcement. These updates help ensure predictable storage behavior and improve reliability for admins managing storage at scale. These fixes will be beneficial to admins, but there is a small percentage of users who will have their OneDrive for Business storage quota adjusted to match their license entitlement. 

[When this will happen]

General Availability (Worldwide): We will begin rolling out early July 2026 (previously late May) and expect to complete in mid-July 2026 (previously June).

[How this affects your organization]

Who is affected

• Microsoft 365 tenants using OneDrive for Business
• Users who are currently over the OneDrive for Business storage quota allowed by their assigned license or extended storage 
• Admins who have set user-specific storage limits above licensed entitlements or extended storage 

What will happen

• User storage quotas will be re-evaluated against license limits during the refresh process.
• Users whose OneDrive for Business storage usage exceeds their licensed quota will be placed into a read-only state per existing policy, which temporarily restricts write access to existing OneDrive content until storage usage is remediated.
• This includes scenarios where:
  • An admin-set user quota exceeds the license allowance, or
  • A user with an EDU license exceeds their licensed storage limit.
• No changes are made for users who are within their licensed storage limits.

[What you can do to prepare]

• Identify users exceeding OneDrive for Business licensed storage limits
  • Review OneDrive storage usage across your organization to identify users whose usage exceeds their licensed quota.
  • Use Identify OneDrive Users Over License-Based Storage Quota | PnP Samples 
  • Review this article: OneDrive site is read-only because storage quota was exceeded – SharePoint | Microsoft Learn
• Take corrective action for affected users. For users exceeding their licensed storage limits:
  • Upgrade the user’s license to increase available storage, or
  • Work with the user to reduce storage usage to within licensed limits.
• Inform your helpdesk and SharePoint admins about this change so they can support users who may be placed into a read-only state.
• If all users are within their licensed storage quotas, no action is required.

[What and Why]

We are updating the Microsoft Teams PowerShell module to use Web Account Manager (WAM) as the default authentication broker for sign-in. This change improves security and provides a more consistent authentication experience on Windows.

A new temporary parameter, -DisableWAM, is available in the Connect-MicrosoftTeams cmdlet, allowing admins to bypass WAM for a single connection if it is not supported in their environment.

This change is available starting with preview version 7.8.1 of the Teams PowerShell module.

[Rollout Schedule]

General Availability (Worldwide, GCC, GCCH, DoD): Rollout will begin in late June 2026 and is expected to complete in late June 2026.

[Impact on Your Organization]

Who is affected

• Admins using the Microsoft Teams PowerShell module on Windows

Platforms/Services

• Microsoft Teams PowerShell module
• Windows

What will happen

• Sign-in for the following scenarios will use WAM as the authentication broker:
  • Interactive sign-in using Connect-MicrosoftTeams
  • Connect-MicrosoftTeams with credential (-Credential)
  • Connect-MicrosoftTeams with AccountId (-AccountId, Integrated Windows Authentication)
• The following sign-in methods are not affected:
  • Service principal with certificate
  • Managed identity
  • Pre-acquired access tokens
• A temporary -DisableWAM parameter is available to bypass WAM for a single connection.
• The -DisableWAM parameter will be removed in a future release.

Known limitations:

• On macOS, Linux, and Windows versions earlier than Windows 10 or Windows Server 2019, existing authentication behavior remains unchanged.
• WAM requires an interactive Windows session with UI access.
• WAM will not work in non-interactive scenarios such as Windows services, scheduled tasks without a logged-in user, or scenarios that run under impersonation.

[Action Required / Recommendations]

• Review any scripts that use the Teams PowerShell module, especially those running in non-interactive environments.
• Update scripts if needed to support WAM authentication.
• Use the -DisableWAM parameter as a temporary workaround if required.

[What and Why:]

To help enterprises respond quickly to critical application regressions, Microsoft is introducing a new Downgrade Version policy for the Microsoft Edge WebView2 Evergreen Runtime. This policy enables administrators to temporarily roll back WebView2 to a previous supported version (N‑1 or N‑2) on a per‑application basis, without disabling Evergreen updates entirely.

This change strengthens enterprise‑grade manageability, giving admins a controlled, time‑bound mitigation option while maintaining the security and update benefits of Evergreen servicing.

This message is associated with Roadmap ID 561329.

[Rollout Schedule:]

General Availability (Worldwide):  We will begin rolling out in early June 2026 and expect to complete by mid-June 2026.

[Impact on Your Organization:]

Who is affected:

Organizations managing enterprise‑managed Windows devices (domain‑joined or MDM‑enrolled) that use WebView2‑based applications

Platforms/Services:

• Windows devices
• Microsoft Edge WebView2 Evergreen Runtime
• Group Policy / MDM (msedgewebview2.admx)

What will happen:

• A new Downgrade Version policy becomes available in msedgewebview2.admx.
• Admins can map specific application executables to a previous WebView2 version (N‑1 or N‑2).
• The Edge Updater installs the target version side‑by‑side.
• The WebView2 Loader redirects only the targeted apps.
• Downgrades automatically expire as new WebView2 versions are released:
  • Apps pinned to N‑1 remain on that version until the next release (then move forward).
  • Apps pinned to N‑2 revert automatically to the current Evergreen version.
• The policy applies only to enterprise‑managed devices.
• No change occurs unless the policy is explicitly configured.

[Action Required / Recommendations:]

No action is required before rollout.

Recommended actions:

• Review existing Group Policy or registry configurations related to WebView2 to understand potential usage scenarios.
• Update internal incident response or app compatibility playbooks to include this downgrade option.
• Share guidance with application owners on when and how to request a temporary WebView2 rollback.

[Compliance considerations:]

An admin control is added that allows configuration of WebView2 runtime versions per application. No other compliance impacts are identified.

[What and Why:]

Microsoft Purview Data Loss Prevention (DLP) is adding the ability to block access to sensitive SharePoint Online and OneDrive for Business files based on an external user’s domain or specific email address (SMTP). This enhancement provides more granular, enterprise-ready control over external access and helps reduce the risk of unintended data exposure when collaborating outside your organization.

This message is associated with Microsoft 365 Roadmap ID 557191.

[Rollout Schedule:]

• Public Preview: We will begin rolling out in late May 2026 and expect to complete by early June 2026.
• General Availability (Worldwide): We will begin rolling out in early July 2026 and expect to complete by mid-July 2026.

[Impact on Your Organization:]

Who is affected: Microsoft 365 administrators who manage Microsoft Purview DLP policies and external users accessing SharePoint Online or OneDrive for Business content protected by DLP.

Platforms/Services:

• Microsoft Purview
• SharePoint Online
• OneDrive for Business

What will happen:

• Admins can configure DLP rules to block access for specific external domains or individual external email addresses.
• External users who are blocked will:
  • See an access denied message
  • Be unable to open or download the file
• Admins can optionally configure allow lists for trusted external domains or users.
• If a domain or user appears in both allow and block lists, block takes precedence.
• This capability is not enabled by default; it applies only when configured in a DLP policy.

Configuration steps:

1. Go to the Microsoft Purview portal.
2. Navigate to Data Loss Prevention → Policies.
3. Create a new policy or edit an existing policy.
4. Ensure the policy scope includes SharePoint Online, OneDrive for Business, or both.
5. In the policy rule, after configuring conditions, go to the Actions section.
6. Select Restrict access or encrypt content.
7. Choose Block access to specific domains or users.
8. Configure one or more of the following:
   • Domains to block (Is), for example partner.com
   • Specific external users (Is), for example [email protected]
9. Optionally configure allow lists using Is NOT for domains or users.
10. Save the rule.

[Action Required / Recommendations:]

• Review existing DLP policies to identify scenarios where external access requires more granular control.
• Identify sensitive or regulated data shared with external users that may need domain- or user-based restrictions.
• Plan communications for internal users, helpdesk staff, and external partners who may experience new access restrictions.
• Update internal documentation related to DLP and external sharing as appropriate.
