Week in brief

Agentic-user sharing policy guidance arrives before SharePoint’s temporary-URL retirement

Two administrator-level issues stand out: Microsoft has documented an off-by-default tenant policy to block external sharing by agentic users, while SharePoint temporary authentication URLs are scheduled for retirement on April 1, 2027, breaking dependent Power Apps and Power Automate functionality. The week also brought opt-in pay-as-you-go billing for storage overages in January 2027, sensitivity-label-protected PDF annotation in late January, and direct OneDrive video sharing in Teams events beginning mid-November. Remaining page edits were largely operational guidance rather than availability announcements.

  • SharePoint temporary authentication URLs will be retired on April 1, 2027. Power Apps and Power Automate functionality that relies on them will break, making dependency identification and remediation a time-sensitive administration task.

    New guidance documents an off-by-default agentic-user sharing block

    A tenant-level policy can block agentic users from sharing SharePoint and OneDrive content with external users. It is off by default and can be scoped to all agentic users or users associated with selected application blueprints through SharePoint Online PowerShell, including first- and third-party applications.

  • An opt-in meter planned for global rollout in January 2027 will charge for SharePoint storage used beyond the included quota. It integrates with Microsoft 365 Archive and requires Azure billing permissions.

  • From late January 2027, users with editing rights will be able to annotate sensitivity-label-protected PDFs in OneDrive for Business and SharePoint on the web. Saving preserves both the annotations and the protections; the notice requires no admin action.

    Teams events will support direct OneDrive video sharing

    Beginning in mid-November 2026, event organizers and producers can use “Manage what attendees see” to share OneDrive videos directly during Teams events, avoiding screen sharing or PowerPoint embedding for playback. No admin action is required.

For SharePoint and OneDrive administrators

Prioritize identifying Power Apps and Power Automate functionality that uses temporary authentication URLs before April 1, 2027. Decide whether to enable and scope the agentic-user policy to all users or selected application blueprints through SharePoint Online PowerShell; it is off by default. If adopting storage-overage billing, arrange the required Azure billing permissions. The PDF and Teams-event updates require no admin action according to their notices.
