Litigation Hold for users no longer at the company

ChrisWebbTech I actually opened a ticket on this very subject because I noticed MSFT closed off shared mailboxes being able to have litigation hold on them and they said if you convert a user to a shared mailbox you break the litigation hold and that data is gone when the cleanup job runs.  Their recommendation was to let the user delete and go into the inactive users area.  There is a powershell to restore it but a bit of a painful process.  IF they gave me bad info certainly would like to know that. 😉

I do like your idea of using a preservation policy instead.
