I am in the process of migrating mailboxes from one exchange 2010 server to another exchange 2010 server. Mailbox boxes are moving fine, but I noticed one issue. Once I moved my mailbox, I went to mail in the control panel and changed it to point to the new exchange server instead of the old one. I type in the new exchange server name, click on check name and it reverts back to the old exchange 2010 server name. I moved a couple other mailboxes and it did the same thing. Mailflow is still working to these moved mailboxes, but I can't get outlook to use the new exchange server name. I hope this make sense. Any ideas or reasons why this is doing this would be greatly appreciated. I am holding off moving the rest of the mailboxes until I figure out why it doing this. I did blow away the outlook profile and make a new one and it still does the same thing. Thanks.
