Sure it can, if you have done a mailbox backup. Once licenesed you pick
exchange as your policy type. You then have the ability to back up the
entire DB (good for DR etc) or a mailbox ot public folder backup. The
mailbox and public folder backups are granular down to the individual
messages.
I'd do one tweak to this, you can't depend on TLD library type or this
