This feature enables Viva Glint admins to delete custom user attributes directly in the platform. This empowers admins to easily update and maintain the structure of user data without requiring support.
Agents & bots in group chats will now be able to authenticate through Entra. When an app requests a user’s Entra token in a group chat, if that user does not have the app installed or Entra consent, they are sent a targeted message. This targeted message is only visible to that user. This message serves two purposes: to ask the user to install the Teams app personally and to open the Entra permission consent dialog. Once both requirements are met, the app can leverage Entra for the requested permissions (e.g., Graph).

We’ve released updates to the following update channel for Microsoft 365 Apps:
Teams Town Hall now matches Teams Live Events in features, offering enhanced controls and attendee experiences. Users are encouraged to transition to Town Hall, as it supports large-scale virtual events and will replace Live Events in the future. Enable IT policies to prepare for this change.
Microsoft 365 LTI, a unified integration for LMS platforms like Canvas and Moodle, will be generally available worldwide on September 15, 2025. It streamlines access to Microsoft 365 tools within LMS, replaces retired Teams LTI tools, and requires admin deployment and communication for a smooth transition.
Starting October 2025, Microsoft Edge on Windows will default to an Adobe-powered PDF viewer for enterprise users, improving performance, accessibility, and features. Rollout completes by March 2026. Admins can manage this via policies, with opt-out available until June 2026. No action needed if ready.
Support for Office 2016, Office 2019, Visio 2016/2019, Project 2016/2019, and related apps ends October 14, 2025. After this, no updates or support will be provided, risking security, compliance, and performance. Upgrading to Microsoft 365 Apps or Office LTSC 2024 is recommended.
Microsoft Teams now supports SlimCore-based optimization for Citrix VDI, offering better performance and new features. Admins must update Citrix Studio policies to whitelist virtual channels (MSTEAMS, MSTEAM1, MSTEAM2) and deploy the Citrix Plugin. WebRTC optimization will be deprecated in the future.
Microsoft Defender for Identity will add new Secure Score improvement actions by late 2025 to better identify identity risks. These include identifying privileged service accounts, removing stale AD accounts, and disabling Entra Seamless SSO. No admin action is needed, but review configurations and notify security teams.
