MC1150123 (Updated) Teams Admin Center: Control External Access by Domain for Specific Users and Groups Previously, external access settings could only be configured at the tenant level, with policy-level settings limited to either inheriting tenant settings or blocking all external domains. With this update, you can assign custom external access policies to users or groups with five configuration options:

Use organization settings: Inherits the tenant's default external access configuration

Allow all external domains: All external organizations are trusted

Allow only specific external domains: Only domains in the allow list are trusted

Block only specific external domains: Domains in the block list are restricted; all others are trusted

Block all: All external domains are blocked for users assigned to this policy

Users assigned a custom policy may interact with different external domains than those defined in the organization-wide settings.

What you can do to prepare

Administrators should begin identifying users and groups that require differentiated external access and plan pilot scenarios accordingly.

During the public preview, configuration must be done via PowerShell using the following cmdlets:

Set-CsExternalAccessPolicy

Set-CsTenantFederationConfiguration

Note: Changes made through these cmdlets will not be reflected in the Teams admin center UI during the Targeted Release.

Once the feature reaches general availability, the Teams admin center UI will support these configurations, allowing policy management via both PowerShell and the UI.

MC1150662 Action Required – Configure Browser Policy to Preserve OneDrive and SharePoint Web Performance and Offline Capability Who is affected:

All users accessing OneDrive for Web, Microsoft Lists, and SharePoint Document Libraries via Chrome or Edge browsers.

Admins managing browser policies for Windows, macOS, and VDI environments.

What will happen:

If no action is taken:

Users will see a new browser prompt requesting permission for local network access when opening OneDrive for Web and Lists.

If users do not click Allow, the following results occur on that device:

Performance acceleration will not be available (loss of faster data access behavior).

Offline functionality in OneDrive Web will not be available.

The experience will be slower and less resilient, and helpdesk contacts will increase due to unexpected prompts and missing offline capability.

When the recommended browser policy is deployed in advance, the prompt is suppressed for the specified trusted Microsoft 365 endpoints and existing performance, and offline behavior are preserved. The policy prevents loss of existing capability and avoids user confusion.		 If no action is taken:

MC1134737 Microsoft Teams: Private channels increased limits and transition to group compliance In response to customer feedback, we are introducing enhanced flexibility, greater scalability, and streamlined compliance management for private channels in Microsoft Teams.

Note: It is important for compliance managers to review and take appropriate action before migration starts for these changes to private channels.

[What's changing?]

Private channels will transition use a channel mailbox instead of individual user mailboxes.

Organizations with compliance policies (retention, legal hold, data loss prevention, or eDiscovery) for private channels must review these policies and must apply policies to the Microsoft 365 group for the channel's team before migration begins to ensure continuity of the policy for a private channel. Existing policies will continue to apply to user mailboxes; post-migration, new data will be governed by policies on the group. Note that policies applied to the team's group can apply to all channels in the team.

After the transition to updated private channels in your organization, private channels will be updated as follows.

Private channels are no longer limited to 30 per team. Instead, private channels can be added up to the limit of 1000 total channels per team.

Private channels can now have up to 5000 members, instead of 250.

Meetings can now be scheduled in private channels.

Compliance policies for private channels are part of the team's group policies instead of the individual user level.

The migration of private channels to the updated capabilities will begin in late September 2025 and continue through December 2025. During this period, private channels will continue to operate normally. Admins and compliance managers should complete any required policy changes by September 20, 2025, before the migration begins. Migration can start or end at different times for each tenant during the rollout period. To track progress, a new PowerShell command will be available for tenants to check whether their migration has started or is completed. This post will be updated soon with details on the PowerShell command.

[When this will happen:]

General Availability (Worldwide): We will begin rolling out late September 2025 and expect to complete by mid-December 2025.

[Action required by compliance managers and admins]

Purview eDiscovery and Legal Hold

With this change, private channel data will move from user mailboxes to the group mailbox, aligning with how shared channels data is stored. Previously, legal holds were applied to user mailboxes since private channel data resided in each member's mailbox. Post-migration, the latest version of private channel message data from each user's mailbox is moved to the private channel's group mailbox. Message edits and deleted messages will not be copied into the group mailbox.

Note: For users on hold, copies of message edits and deleted messages will remain in the user's preserved library folder until the hold expires, while the latest version of private channel message data from each user's mailbox is copied to the private channel's group mailbox.

Before migration

If a legal hold exists for a private channel, admins must also apply the policy to the team's group, in addition to the policy already applied to users' mailboxes, in order for a hold to apply to new data generated and stored in the private channel's mailbox. Note that policies applied to the team's group can apply to all channels in the team.

Screenshot 1: Setting up a new hold in Microsoft Purview compliance portal.

After migration

For existing holds admins will need to ensure that the hold is applied to the user mailbox as well as the new group mailbox, in order for a hold to apply to existing and new message data. Any new legal holds will need to be applied to the group.

For complete eDiscovery, include both the private channel's users' mailboxes and the team's group mailbox to retrieve pre-migration messages, message history, and post-migration new content.

Screenshot 2: Configuring an eDiscovery search in Microsoft Purview compliance portal.

Purview Data Loss Prevention (DLP)

With this change, private channel messages will be included as a part of the DLP policy scoped to the private channel's team's group, as opposed to the user mailbox.

Before migration

Admins must modify the "Teams chat and channel messages" policy for private channels to add the team's group containing the private channel, in addition to the user mailbox, in order to include new private channel messages in a policy. Note that policies applied to the team's group can apply to all channels in the team.

After migration

Ensure that "Teams chat and channel messages" policy for private channels is scoped to the team's group containing the private channel.

Screenshot 3: Configuring a data loss prevention policy in Microsoft Purview compliance portal.

Purview Retention Policy

After this change, creation of new private channel-specific policies will not be possible in the Purview portal. Instead, "Teams channel messages" policies applied to the team's group will now include private channels. Existing private channel policies will remain in effect and preserve all held message data in user mailboxes. Editing of existing policies will not be supported but policies can be removed.

Before migration

Apply current private channel retention policies (previously on user mailboxes) to Teams channel messages to include the team's group, in order to include new private channel messages in a policy. In Microsoft Purview compliance portal, go to solutions > Data Lifecycle Management > Retention policies. Note that policies applied to the team's group can apply to all channels in the team.

After migration

If the parent team's group retention policy differs from the private channel's policy, create a new or equivalent policy to ensure consistent retention.

Screenshot 4: Configuring "Teams channel messages" for a retention policy in Microsoft Purview compliance portal.

Frequently asked questions

How can admins identify a user's private channel memberships?

Use Teams Admin Center under team settings, or run PowerShell: Get-TeamChannelUser to list members.

When is compliance manager action required?

If a policy (legal hold, eDiscovery, retention, DLP) applied to a user's mailbox, in order to include private channel messages, differs from the team policies for the team hosting the private channel. Policies must be applied to the team's group in order to include new private channel messages in a policy. Note that policies applied to the team's group can apply to all channels in the team.

During eDiscovery for users on hold or during migration, search both user mailbox and group mailbox for complete data on a private channel.

What if no action is taken?

User-level policies will not apply to a private channel's new message data. Team-level policies will apply to private channels.

Why isn't Microsoft automatically applying policies from user mailboxes to a private channel's team?

Tenant admins and compliance managers must assess and apply policies as needed. Group policies apply to all channels in the Team. Some user mailbox policies are intended for all of a user's messages, and some are intended for private channel messages. Each organization must review and decide on policies.

Is there any impact to end users?

During migration, users may see duplicate search results in Teams searches-both links will navigate to the same content in Microsoft Teams.

MC1150662 Action Required – Configure Browser Policy to Preserve OneDrive and SharePoint Web Performance and Offline Capability [Introduction]

Upcoming privacy-related changes in Chromium-based browsers (Google Chrome and Microsoft Edge) will increase restrictions on local network access. When enforcement begins, users accessing OneDrive for Web (and some integrated Microsoft 365 experiences such as Microsoft Lists and SharePoint Document Libraries) will encounter a browser permission prompt for local network access unless the required policy is in place. If the permission is not allowed, performance optimizations and offline capabilities powered by OneDrive and Share Point will not be available. This communication provides required administrator actions to prevent loss of functionality.

[When this will happen:]

Chrome and Edge will roll out this privacy related change as part of Chromium 141 at the end of September.		 Updated September 15, 2025: We have updated the content. Thank you for your patience.

Deploying the managed LocalNetworkAccessAllowedForUrls policy will override any prior per-user deny state and enforce the allow setting once the policy is applied to the device/profile; no end-user action is required after policy propagation.

If you need immediate remediation before policy reaches the device, have the user open the affected OneDrive site, use the site (lock) icon, reset or change the local/network device access permission to Allow, then refresh.
