I am on a test environment moving mailboxes from 2003 to 2010. All of the mail boxes are moved except one that is still moving. When I look at the log it says it has started the final sync. This message was logged at 9 PM last night. It is now 18 hours later and it's still sitting at 95%. All of my mailboxes total 70 GB and this mailbox is 12 GB with 160,000 emails and over 15,000 folders.
Any ideas what might be going on and any way to verify what's going on?
