If you have used the Email Archiver tool on a matter and the matter now needs to be reinstated back to active or a user may need to access the emails again for some other reason, you can reverse the archiving process.
All you need to do is change the source and the destination databases around (ie the direction you want to move the emails) and re-run the process.
This will then move the emails back from the archived database back to the production/live database.
