Microsoft Teams will introduce a Restart Event feature for live events with unrecoverable failures, rolling out worldwide from January to February 2026. Organizers can restart events to minimize disruption, with no admin setup needed. Attendees may face brief interruptions but can rejoin seamlessly.
Microsoft Purview introduces new opt-in cmdlet parameters to remove retention holds from inactive mailboxes, enabling permanent deletion while respecting compliance. The ExcludeFromAllHolds parameter removes most holds except eDiscovery and litigation holds, and RemoveComplianceTagHold targets only Compliance Tag holds. Rollout begins December 2025.
Starting January 2026, IT admins can customize Teams recording and transcription notification messages and privacy links per meeting policy, aligning consent language with organizational needs. Custom messages have a 200-character limit, support explicit and implicit consent, and apply only when enabled. Default messages remain if no custom text is set.
Microsoft 365 Copilot declarative agents will upgrade to the GPT-5.1 model with an auto architecture by mid-January 2026. The upgrade enables advanced reasoning for complex queries, requires no admin changes, is enabled by default, and affects all tenants using these agents. No action or compliance concerns are noted.
Microsoft Teams will use peer-to-peer update distribution via Delivery Optimization starting December 2025, enabling devices on the same network to share update files. This reduces CDN bandwidth use, speeds updates, and saves up to 30% bandwidth. No admin action is needed, but network policies should allow Delivery Optimization.
Microsoft Defender for Identity v2.x sensors will start using new IP addresses from the AzureAdvancedThreatProtection service tag range beginning mid-December 2025. Organizations restricting outbound IPs must update firewall rules to allow this range to avoid connectivity loss; no action is needed if the full range is already allowed.
Microsoft Purview Data risk assessments now support item-level investigation and remediation of SharePoint data. New insights like sensitivity label and sharing link information help users identify items at risk of oversharing. Users are empowered to remediate overshared items by resolving, notifying, applying a sensitivity label, or removing sharing links for selected item(s). This helps organizations proactively reduce data exposure, strengthen compliance posture, and ensure sensitive data are only accessible to the right people.
Express voice enrollment makes registering your voice in Teams fast and easy. Your profile enables features like voice isolation, speaker recognition, identification in a meeting room and transcripts, and enhanced meeting recaps and insights from Microsoft 365 Copilot. If you haven’t enrolled, you’ll get an in-product prompt to opt-in and enroll your voice profile simply by speaking in a meeting. Admins can enable or disable this feature for their organization.
The Data Security Posture Agent is designed to expand the capacity of data security admins as they proactively work to stay on top of a dynamic data and risk landscape within their organization. Its primary job is to help discover sensitive data across your data estate. This agent is designed to analyze and search documents, emails, and messages that match the natural-language discovery intent requested by the user and assess associated risks. By moving beyond traditional keyword and information-type analysis and harnessing the power of LLMs, this agent enables organizations to identify risks based on the actual purpose and context of the content and take appropriate action.
