Thanks for your reply. Couple of things. I'd like a repository of all our mailboxes in PST format so that I can drag the ones of former staff into a folder so that if someone needs an email that's in one of their mailboxes, I can just search the relevant mailbox or even give them a copy of the PST to load into their Outlook if they need to search themselves. Also, i'd like to have the whole repository of PST files stored off-site as well. Lastly, in this case, I'd like to save the former employee's mailboxes so I can remove them in Office 365 so they don't get backed up anymore.
