Outlook 2007 Infinite Folder Nesting

There's a user on our exchange who moved a subfolder of his inbox into a subfolder beneath that, and now an infinitely nested folder loop has been created (see screenshot).

This is prevalent on both Outlook 2007 and on OWA so it appears to be an issue server side, however I can't think what will have caused it let alone how to resolve the issue.

I've tried to create a copy of the folders and then move the copy back to a copy of the original folder structure, however when I've done this, the 2 looping folders are subsequently empty (When originally, they were not).

As this issue is also visible via OWA, the usual local OST fixes etc don't have any effect, and I'm drawing a blank on how this would be resolved and wondered if anyone has seen anything like this before and how to fix it?

The local client is Outlook (Office 2007) running on XPSP3 and the exchange server is running Windows Server 08 and Exchange 2007.

Thanks

Solution 1:

NOT for the faint of heart...use MDB Viewer to delete the folder:

1. MDB -> Open Message Store
2. MDB -> Open Root Folder
3. Open IPM_SUBTREE, then inbox, then finance, then budget. Select Finance. Change operation to Delete folder. Call function. Select DEL_FOLDERS and DEL_MESSAGES. Click OK

Like I said, not for the faint of heart. Know what you're doing before you totally hose the mailbox.
