I didn't make it clear enough to an end user with a 4 GB mailbox how the archive feature works. He didn't know that it was going to create a second set of folders that he would have to look through. I think that Exchange 2010 addresses his concern but weren't ready for it. How can the user make it look like it used to in Outlook (all under his Exchange mailbox) yet some of the storage is in a pst? I was thinking something like shortcuts but Outlook doesn't have that to my knowledge.
I hope I made myself clear enough explaining it to you.
