Stub mailbox left behind after move to another server

Something strange that I have never seen before in all my years with Exchange. I have two Exchange 2003 SP2 servers and I built two new ones on improved hardware. I migrated over a few users for testing. Everything went fine and the users had no issues at all. Today, I noticed that there are traces or stubs of the moved mailboxes still on the original server. They have a red flag on them and they are only a fraction in size of the original. I tried to purge this mailbox and I get a message saying it is already connected to an existing user even though its marked for deletion. Of course, I cannot reconnect it for the same reason. Two questions. Why is this happening? I have moved thousands of mailboxes and never saw this. How do I get rid of these? I won't be able to decommssion these servers until I remove these mailboxes. This is a show stopper for me because I still have about 2000 more mailboxes to migrate.

I have seen this one or two times and Exchange has removed correctly each time. As long as the red cross is on the mail box you should be fine.

Actually, I found the answer in the knowledge base article below right after I posted this.


This is a known problem with Exchange 2003 SP2. I have been on SP2 for a long time and have moved many mailboxes since I installed SP2 and never had this problem so it must have been some recent security update that caused this or a hotfix.

I had this issue with my E2k3 to E2k7 migration.  To fix this you need to issue the move command from the E2k7 box to move the mail box back to the E2k3 box.  And in the process it will delete the stub object for you.  You will get an error similar to the following.

Error was found for User Name(UserName@domainname.com) because: Error occurred in the step: Preparing mailbox to be moved. Failed to copy basic mailbox information with error: A duplicate mailbox was found due to problems during a Move Mailbox procedure. The duplicate mailbox has been deleted. Try again later., error code: -1056749241
