Hi All,
I'm looking for an report or an possibility to check how big is the archived mail size from exchange mailboxes.
We are using mail archiving and replace all mails with attachments older than 1 yer with an stub.
Now we are migrated to O365 and we want to deactivate the archiving function.
To check the needed space in O365 we want to know how man space is archived for each mailbox.
to you have an hint how can i get this information ?
