Hello,
I need an advise on how to better handle a mailbox owner when a user is no longer active (e.g. retired, resigned, etc.) Currently, these users have O365 Pro Plus G License and Exchange Plan 2G. I was told that when a license is removed from any users, the retention period is only 30 days and after that, their mailbox is gone. We would like to prevent that from happening. We would like to at least keep their mailbox for sometime, in case there's a litigation, we still have their mailbox. We also need to remove their license so that we can apply it to the new employees. Please advise, thanks.
Alopez
