I have a number of deprovisioned user mailboxes I want to move to EXO. Rather than buy licenses for all mailboxes I only want to purchase as many as necessary and reuse them.
Once I apply a license to a user and enable litigation hold, is there a set amount of time before EXO picks up that litigation hold has been enabled? Is it instant, an hour or 24 hours etc. Or can I remove the license right away?
"The litigation hold setting may take up to 60 min to take effect."
I would personally probably wait twice that just to be safe, as the last thing you would want to do is put something on lit hold, unlicense it, than do something like delete it, and assume the data is saved when it is really not.
Get-Mailbox <name of mailbox> | Format-List LitigationHold* should be a good way to tell if it worked.
