Starting October 2025, Global and AI Administrators can reassign ownership of shared agents in Microsoft Copilot Studio and M365 Agents Toolkit to licensed users. The new owner gains full control and access; the previous owner loses all rights. Rollout occurs in two phases during October 2025.
Outlook will introduce a Copilot chat feature to summarize emails with one click, available to Microsoft 365 Copilot license users across all platforms by November 2025. It requires no admin setup, respects existing policies, and aims to save users time and improve focus.
Declarative Agents will be added to Copilot Chat in classic Outlook for Windows starting late October 2025, enabling customizable plugins and connectors. Enabled by default for Copilot license tenants, admins can manage agents via Microsoft 365 admin center. Advanced features require admin opt-in and billing setup.
By October 2025, Microsoft Copilot Studio will have an updated icon across its web and Microsoft 365 Copilot interfaces. This visual change aligns with the Microsoft 365 Copilot brand, affects all users, involves no functional changes, requires no admin action, and has no compliance impact.
Teams Rooms on Android and Teams Phone devices face calling and pairing failures due to Continuous Access Evaluation (CAE) policies affecting token validity. To ensure device stability and reliable calling, disable CAE on all Conditional Access policies for these devices, as this does not significantly reduce security.
Microsoft Teams will introduce Trust Indicators—visual badges showing if a user is external, a guest, or anonymous—to help identify participants and reduce oversharing. Rolling out from September 2025, this feature is on by default with no admin action needed. Admins should review documentation and inform support teams.
Microsoft Teams is transitioning to the secure cloud.microsoft domain by September 2025, enhancing security with Microsoft’s exclusive top-level domain. Users will be auto-redirected with no action needed. Admins should update references, educate users, and ensure network access to *.cloud.microsoft. Compliance impact is minimal.
Microsoft Defender for Identity introduces a new opt-in post-deployment configuration for unified sensors (v3.x) enabling RPC monitoring via the Unified Sensor RPC Audit tag. Rollout starts late September 2025, enhancing advanced identity detections with visibility in device inventory. No action needed unless enabling the feature.
Microsoft Purview eDiscovery will enhance metadata in item.csv reports starting October 2025, adding fields like status, error details, custodian, sensitivity label, encryption, and SharePoint content type ID. These updates improve item-level insights, error traceability, and support automation. Admins should update workflows and documentation accordingly.
We are announcing the ability to quantify time and money saved by automations delivered at flow, environment, and tenant level in Power Automate. This feature will reach general availability on October 27, 2025, at Power Platform Conference 25.
