There may be a need to unstrip, unstub, rebuild, reconstitute, export, reconstruct or put stripped messages from Archive Manager database back to Exchange Mailbox(es).
The easiest way to achieve this is to install the Archive Manager Offline client on the user's client PC. The result of successfully installing the Offline Client is that a copy of the archived messages in the form of PST will be created on the user's PC. Once the Archive Manager PST has been created the messages that needs to be restored into the Exchange Store can be found and then dragged back into the user's mailbox.
The second way is to search desired emails and export search result to a PST file by means of Archive Manager Search Exporter then attach pst to a user's mailbox and drag emails from PST into the mailbox.
