I'm deploying a mail archiving solution by using the new Exchange Mailbox agent.
My primary archive storage is a disk library. Now customer wants to duplicate archived e-mails from disk library to a tape library and store archived e-mails on tape for, say, 3 years.
I wonder if mail recall function works ok if the requested e-mail is stored on tape only?
Does recall process happen in an unattended manner or an intervention of backup admin is required?
