Currently I’m removing our old Exchange 2003 Server. We migrated all our users to an Exchange 2007 Server. When looking in the mailbox store on the Exchange 2003 server, I noticed mailboxes of users which were migrated to Exchange 2007. Weird I thougt. As we had some issues with linked mailboxes, I looked if these mailboxes were the same as the converted linked mailboxes. This wasn’t the case.
So I just wanted to delete these mailboxes, because the mailbox on Exchange 2007 was already mapped to the Windows user object. While trying to delete the mailbox I got an error :
ID no: c1034ad6
Exchange System Manager
The operation cannot be performed because this mailbox was already reconnected to an existing user
After trying to look why this error appeared, I thougt of some ways to resolve this issue:
- Find the active mailbox with the same directory name and the delete
the mailbox from that user. Then purge the mailbox. Reconnect the mailbox we want to keep (the one deleted from the active user) to the original user. - Dismount the mailbox database, rename the database (.old) and mount the mailbox database. This will create a new mailbox database.
Because I still was investigating this issue, I didn’t use any of the 2 options yet. I ran the Cleanup Agent on the mailbox store. And….voilá…the mailboxes were gone. Just as simple…
Actually last week we had moved some mailboxes from one store to another mail box store in bulk. All the mailboxes moved successfully and we got no error in event logs also.
Now we have an issue that some mailboxes are still showing in their previous stores in disconnect state while they are showing in their new store also as well properly. It’s not for all the mailboxes, only fewer
Mailboxes having this issue.
Now we want to purge these disconnected mailboxes from our Exchange System manager. I tried to do it manually running cleanup agent as well as trying to purge them, but I can’t. I searched on net and found
Article no.930363 relating this issue but it was not helpful for us.
Can you please give us an effective solution so that we could resolve this issue?
Do you receive an error when you try to run the cleanup agent?
What errors appear in the eventlog?
Quickest way to clear them out is to try moving the mailbox back to the mailstore that houses your ghost mailbox. It’ll error, leaving it in the new mail store and deleting the ghost mailbox.
Easy
Awesome, I just tried moving the mailbox back to that server like you said. It errored and the old one disappeared.
Thanks mate!
While the migration of old Exchange 2003 Server to an Exchange 2007 Server is completed, sometimes System Manager stops responding, the overall process is Interrupted due to which error message comes that the operation can not be performed because mailbox is in use or already reconnected to existing user.
You did right steps for the same as i do.
I get the active mailboxes with the same directory name and delete the mailbox and its create a new mailbox database.
