MC1152315 - Update Principal owner of a SharePoint Embedded user-owned container through SPAC and PowerShell

To improve administrative control and support organizational transitions, SharePoint Embedded now allows administrators to update the principal owner of user-owned containers directly through the SharePoint Admin Center (SPAC) or via SharePoint PowerShell cmdlets. This update addresses common scenarios such as user departures or team restructuring.

General Availability (Worldwide): Rollout will begin in late September 2025 and is expected to complete by late October 2025.

• Who is affected: SharePoint administrators managing user-owned containers in SharePoint Embedded.
• What will happen:
  • Admins will be able to update the principal owner of user-owned containers via SPAC or PowerShell.
  • This capability is limited to user-owned containers only.
  • The update helps maintain continuity and access control when users leave or teams change.
  • No changes will be made to existing containers unless action is taken by an admin.
  • The feature will be available by default on SPAC; no opt-in required.
  • The feature will not be readily available by default on PowerShell. The admin has to update it to the latest version. 

• Review user-owned containers that may need ownership updates.
• Use SPAC to select a container and update the principal owner via the General tab.
• Alternatively, use the updated SharePoint PowerShell cmdlets to perform the same action. Ensure your SharePoint PowerShell module is updated to the latest version.
• Communicate this change to helpdesk or support teams.
• Update internal documentation if ownership management is referenced.
