Sites Without an Active Owner

The question it answers: Which SharePoint sites have no active owner, or only one, so nobody reviews who has access?

Every site needs someone who can answer access requests, review sharing and decide when content can go. Sites whose group has no owner, whose owners have all left, or whose primary owner is disabled or deleted are ungoverned - nobody reviews who has access.

Note

A site whose primary owner is gone may still have working secondary admins - check them before assigning a new owner. ‘Only one active owner’ is a warning: one leaver away from ownerless.
