We have recently built a new exchange 2003 server that is in the same site as our old one. We were able to use the system manager to move mailboxes from one server to the other. However, when outlook opens the moved mailbox; we are only able to see the inbox folder, clicking into other folders or areas (contacts, calendar etc.) freezes outlook. I've used exchange best practices tool and nothing seems to be wrong. Never seen this problem before.
