SProbot highlights sites which have no ownership assigned, or have only a single owner assigned. You can then use the Assign admin action to ensure that sufficient ownership is assigned.
Why should this be reviewed?
SharePoint and Teams content is only properly managed when the correct ownership is in place. A workspace becomes orphaned when its owner leaves and their account is deleted, leaving the Microsoft 365 owners group and/or site owners group empty.
- Workspaces with no owners run the risk of content becoming stale, and even with sensitive content being inadvertently exposed because there is no one accountable.
- Workspaces with only a single owner are risky because they are only a single departure away from becoming orphaned.
Governance best practice is for content to ideally have more than one owner, to ensure failover in the case of a person not being available for an extended period of time.
How do you see which sites are orphaned or have only a single owner?
In Reports > Reviews, choose the Single-owner workspaces review, or use the Orphans cleanup tool in Cleanup > Tools.
In either of these reports, you can select one or more workspaces and use the Access > Assign admin action to assign an owner.
All changes to ownership are displayed in Reports > Activity history.
