M The SharePoint SendEmail API (SP.Utilities.Utility.SendEmail) is used to send emails directly from SharePoint through custom code, workflows, or Power Automate flows. Microsoft will retire this API on October 31, 2025, after which emails sent through it will no longer work. Admins can use Microsoft Purview audit logs to identify where this API is currently in use.

Solution: Move to modern alternatives like the Microsoft Graph API or Outlook connector to handle email-related automation.

The “Visualize the List” and “Visualize the Library” features in SharePoint Online allow users to quickly generate Power BI reports directly from SharePoint lists or libraries. To streamline the reporting experience, Microsoft has planned to retire these features.

After this retirement, users will no longer be able to use legacy integration to create new reports directly from SharePoint lists and libraries. In addition, previously published reports created using legacy integration will also no longer be accessible.

Solution: Users will need to use alternatives like Export to Power BI or Power BI Desktop to create reports from SharePoint data.

Ref: https://admin.microsoft.com/Adminportal/Home#/MessageCenter/:/messages/MC1156359

Microsoft will retire desktop notifications in Viva Engage by mid-November 2025 to align with Microsoft 365’s unified notification system. The “Allow users to enable desktop notifications” and “Desktop push notifications” options will no longer be available for both admins and end users respectively. As a result, users will no longer receive @mention and community announcement notifications via desktop push.

Solution: Encourage users to rely on in-app notifications through Teams, Outlook, and Viva Engage.

Ref: https://admin.cloud.microsoft/?#/MessageCenter/:/messages/MC1169069

• Keep content up-to-date by detecting broken links, retiring inactive pages, and identifying content gaps.

• Assist as a co-author with templates, layout suggestions, and FAQs.

• Respond to natural language questions and guide users to the right information.

From November 1, 2025, individual sites can opt in at their own pace.

Ref: https://techcommunity.microsoft.com/blog/spblog/introducing-knowledge-agent-in-sharepoint/4454154

Microsoft Teams now supports Entra-based authentication for agents and bots in group chats. When a bot or app requests a user’s Entra token, Teams will verify whether the user has the app installed and the necessary consent granted. If not, a private prompt appears, guiding the user to install the app and authorize permissions. Once consent is complete, the app can securely access requested permissions.

Ref: https://www.microsoft.com/en-US/microsoft-365/roadmap?filters=&searchterms=503557

Microsoft is updating the quarantine view to improve usability and consistency:

• Quarantined messages will now be displayed per individual recipient instead of grouping multiplerecipients in one row.

This feature will reach general availability by November 2025.

Ref: https://learn.microsoft.com/en-us/microsoftteams/malicious-url-protection-teams

Granting apps permission to send emails on behalf of mailboxes is now simpler. Currently, admins have to assign permissions individually for each mailbox using PowerShell. With App Role-Based Access Control (RBAC), admins can assign the SMTP.SendAsApp role to an app for group-based or scoped mailbox access. This eliminates per-mailbox configuration and streamlines OAuth SMTP onboarding.

Ref: https://www.microsoft.com/en-US/microsoft-365/roadmap?filters=&searchterms=498356

Microsoft Entra ID will introduce support for passkey profiles in the passkey (FIDO2) authentication methods policy.

Note: Meeting organizers must have Teams Premium or Mesh Trial licenses to schedule immersive events, which currently support up to 300 attendees.

Ref: https://admin.cloud.microsoft/?ref=MessageCenter/:/messages/MC1123552

Microsoft is launching Auto-Archiving for Exchange Online in public preview by November 15,2025 (for tenants opted into Target release option). When a mailbox exceeds 96% of its quota and archive mailbox is present, older emails (excluding those tagged Never Move to Archive) will be automatically transferred to the archive mailbox. This prevents storage overflow and ensures uninterrupted mail flow.

Ref: https://techcommunity.microsoft.com/blog/exchange/auto-archiving-for-exchange-online/4459735

Ref: https://admin.microsoft.com/Adminportal/Home?#/MessageCenter/:/messages/MC1138798

Microsoft Defender for Office 365 is upgrading the email quarantine preview experience to be more consistent, secure, and user-friendly.
Key improvements include:

• Removal of the plain text view for uniformity.

Ref: https://admin.cloud.microsoft/?ref=MessageCenter/:/messages/MC1163922

Microsoft Purview is enhancing security and compliance by enforcing Entra Conditional Access policies for eDiscovery admins and introducing a new ‘FilePreviewed’ audit log activity.

In clear, currently, eDiscovery admins can access SharePoint Online content in Purview regardless of compliance with Conditional Access policies. With this update, non-compliant admins, such as those not meeting MFA or trusted network requirements, will be blocked from accessing SharePoint content through the Purview portal. Additionally, every file preview action will now be recorded under the new ‘FilePreviewed’ activity in audit logs.

Ref: https://admin.cloud.microsoft/?#/MessageCenter/:/messages/MC1181768

The “Files” tab in Microsoft Teams channels will be renamed to “Shared.” Currently, it only displays files from the channel’s document library.

Ref: https://admin.cloud.microsoft/?#/MessageCenter/:/messages/MC1166868
