11 devices need a look. To remove a device someone no longer uses, or a leaver's, open the Exchange admin centre, Recipients > Mailboxes > the mailbox > Mobile devices, and remove it (or block it there first). Waiting devices are allowed or blocked in the same place.

48 devices on 42 mailboxes; 38 synced in the last 30 days. A device keeps its partnership until it's removed, so old phones stay listed long after they're replaced.

The Outlook app supports modern sign-in and app protection policies; the built-in mail app over ActiveSync is harder to control.
