So, a client wanted to clean up their aad hybrid disabled users.

Re-configured sync, they were specifically told that they need to prep their work items and they have 60 days.

Lo and behold 60 days pass and disabled user that was moved from hybrid mailbox is actually important without us being notified.

EXO deletes the mailbox, still exists on prem as o365/remote mailbox.

We also have the Veeam backup of the shared mailbox i think.

What would be correct way to recover this in functionality?
