How to make sure every Microsoft 365 workspace has an owner
Diesen Beitrag auf Deutsch lesen
A five-step ownership process identifies ownerless, single-owner and leaver-owned workspaces, then assigns accountable people and confirms ownership quarterly.
TL;DR
Rencore recommends mapping every Team, SharePoint site and Microsoft 365 group, requiring at least two active employee owners, reassigning ownership during leaver processes, and reviewing ownership quarterly. Workspaces with disabled owners, external guests or sensitive content should be prioritised because ownership gaps can cause stale access, oversharing, unmanaged storage and weak audit accountability.

Governance takeaway
- Makers: Check that workspaces they create have named active owners, because ownership determines who answers for members, content and lifecycle.
- Admins/CoE: Inventory Teams, SharePoint sites and Microsoft 365 groups, flag ownerless or disabled-owner workspaces, and run quarterly confirmations with recorded decisions.
- Security/Compliance: Prioritise workspaces with guests or sensitive content, because missing ownership can enable stale access, oversharing and an incomplete audit trail.
- Leadership/Business: Ensure joiner, mover and leaver processes reassign ownership before accounts close, preventing workspaces from becoming orphaned.
