How does Purview/data lifecycle management on Mailboxes work for deleted mailboxes?
In the mailbox is under the scope of a Purview retention policy/hold, you will be prevented from deleting it, until all holds are removed. You can however delete the corresponding user object, which in turn transforms the mailbox as "inactive" one. Data will still be preserved until for the duration of the hold.
Thanks Vasil. If this is the case, why do you think I would have been able to delete a number of non-user (shared) mailboxes up to this point? I've been heading a project to clean up 20yrs of mailboxes, and it's only recently that I've been prevented from doing so. I wasn't really paying attention to user vs shared up until now, but I THINK most of what I managed to remove were shared, mostly unused ones made without thinking in the past. Is there a minimum data trigger that makes a mailbox eligible for retention coverage?
It depends where you initiate the deletion from. You can still delete the user object, just not the mailbox directly. And if you remove the license before the user object deletion happens, the Inactive mailbox "conversion" doesn't occur.
