Unable to Purge a mailbox after a mailbox move

I am unalble to purge a mailbox that was move from one exchange 2003 server to another, the mailbox was moved to the new server however it hung on saving changes to the directory.  We manually set the homeMTA, homeMDB, and msExchHomeServer fields in AD.  They are now able to connect to the new mailbox however the mailbox on the old server has the red X on it but when i try to purge it i get the error "The Mailbox cannot be performed because this mailbox was already reconnected to an existing user."

So you can log onto the mailbox, then the easiest way round this is to exmerge or export the data to a pst file (if its not too large) and then delete the mailbox. Run the cleanup agent on the old store, then try purging the mailbox from the old store. Once done try reconnecting the mailbox from the new store.
You can also try moving the mailbox again, it will fail, but exchange will then know about your second mailbox and will try and fix the issue.
What you need to do is

export the data to a pst file using outlook or exmerge from the new mailbox
try to reconnect the old mailbox and if that works then export the data from it as well
compare the size of both the mailboxes in the ESM (number of items)
check the deleted items retention period for the mailboxes on the mailbox store of both the stores. it should not be set to 0
remove the exchange attributes of the user that owns this mailbox
run cleanup agent on the old server's mailbox store
try to purge the old mailbox from the old server's mailbox store
once that works fine connect to the mailbox store on the new server and run the clean up agent
this would show a red x on the mailbox for that user
right click and click on reconnect and conect it to the same user
