Tech Tip: Resolve a common problem with moving mailboxes to Exchange 2003

Learn about a problem you may encounter when attempting to move a mailbox from Exchange 5.5 to Exchange 2003, and find out about possible workarounds.

Many administrators are in the process of migrating their company's Exchange organization user mailboxes from Exchange 5.5 to Exchange 2003. The most common method of doing this is to build an Exchange Server 2003 system, join the existing 5.5 site, and use the Move Mailbox task to push the mailboxes to Exchange Server 2003. After the initial installation is complete, moving mailboxes is pretty easy.

As with any new product, however, there's a learning curve. Even moving mailboxes can present problems that aren't immediately apparent. In another article, we told you how to possibly work around a problem with moving large mailboxes.

Here's another problem you may encounter when attempting to move a mailbox from Exchange 5.5 to Exchange 2003. In this scenario, the mailbox move fails, logging the following events:

Event Type: Error
Event Source: MSExchangeAdmin
Event Category: Move Mailbox
Event ID: 9164
Description: Failed to open object '[Mailbox Distinguished Name]' on server '[Server Name]'.
Error: There is no such object on the server.

Event Type: Error
Event Source: MSExchangeAdmin
Event Category: Move Mailbox
Event ID: 1008
Description: Unable to move mailbox '[Mailbox Name]'.
Error: There is no such object on the server.

Your first step may be to check out Microsoft's Knowledge Base. But, while a search turns up several possibilities, none of them apply to your specific situation. What could the problem be?

Take a look at the attributes of the mailbox on the Exchange 5.5 server. Is the mailbox marked hidden from the Global Address List? If so, unhide the mailbox, wait for the directory to replicate, and try the move again. The mailbox move will likely complete successfully now with no problem.
