I am attempting to restore a specific users mailbox from backup. The user does not exist in AD/Exchange. I have the job set to create the user. When I run the job it creates the user and puts mail in their box (I can see it through OWA). About about 50% of their mailbox is restored the job stops with "Access Denied" and then the mail disappears!
I am connecting using my personal domain account in the target domain. If it matters, the BE server is in a different domain (no trust - old left-over before combining data centers). But clearly I have permissions if BE is actually creating a domain account and starting to put mail in the user's mailbox!
