Export a Mailbox    

The “old” way for an administrator to export a mailbox is by using Outlook. Basically, the administrator resets the password of the account then configures Outlook with the user’s mailbox that the administrator wants to export (or backup). Once Outlook synchronizes the mailbox’s content, it will create a data file.  

It is now possible to export a mailbox from Exchange Online with the Content Search feature on Office 365. This export only requires the eDiscovery permission (see the following screenshot).
