Me and my team was being tasked to move all the EV Archive emails to Exchange 2010 SP3 RU5 Archive Mailbox directly. Is there any official approach on how to do this? Most of the article that i've found mainly discussed on how to export the EV files to user mailbox; not user archive mailbox?
what you're looking to do isnt supported natively in EV. we can do this for you at Trace3 and it'll require a migration tool. feel free to send me a PM with your contact info and we can discuss it
