Microsoft Copilot (Microsoft 365)

Updated April 24, 2026: We have updated the timeline. Thank you for your patience. Copilot is making it easier to manage scheduling conflicts by automatically rescheduling 1:1 meetings and personal events. Within the meeting event form, users can indicate which events are more flexible and allow Copilot to reschedule them if conflicts arise. Users can also set preferences for when rescheduled events should occur. Copilot will detect double-bookings and automatically move these flexible events to a better time—saving users time and reducing manual coordination.A Microsoft Copilot license is required to utilize this functionality. [When this will happen:]Targeted Release: Rollout begins mid-February 2026 (previously mid-November 2025) and expected to complete in May 2026 (previously end of February).[How this affects your organization:]Copilot users will gain the ability to automatically r

Microsoft Purview

Updated April 16, 2026: We have updated the timeline and content. Thank you for your patience. [Introduction] To strengthen security when Microsoft Purview interacts with Microsoft 365 services (Exchange, SharePoint, OneDrive, and Teams), we’re updating how roles are managed in Microsoft Purview. Certain admin roles in Purview will now be mapped to three newly created roles in Microsoft Entra. Role assignments will be synchronized between Purview roles and Entra roles without any customer action. This ensures that user permissions and identity flow securely from Purview to Microsoft 365. M365 services will only allow high-privileged operations like search/export to Purview users with the correct level of permissions in Entra, further protecting customer data. [When this will happen:] General Availability (Worldwide): Rollout begins mid-February 2026, finishes by late May 2026 (previously
