Exchange 2010 behaviour with multiple mailboxes attached to Outlook 2010

This was has been baffling me for a while now.  We have successfully migrated over to Exchange 2010 SP1.  Currently our users are still using Outlook 2007 to connect to Exchange.  When testing Outlook 2010 I have noticed an annoying behaviour in that people who I had previously attached their mailboxes to my Outlook (in 2007), are also now showing up in Outlook 2010.

The annoying this is, this is a clean profile, I have added NO additional user mailboxes, yet these still show up as available within Outlook.  I can't navigate to Add / Remove mailboxes, because there is nothing there to remove, yet this phantom mailboxes are still there, and still accessible.  

How do I get rid of them?  I have to think this is a server side setting on Exchange 2010 / or stored in AD, as this test machine is a clean build with a clean profile.

I've ran into this issue as well. I can't remember the exact attribute, but if you view your active directory account with ADSI Edit, you'll find these extra mailboxes in there.

Thanks, that pointed me in the right direction.  The attribute is called "msExchDelegateListLink" and you have to remove your entry from the other mailbox, rather than look at this entry in your own account.

Still, problem solved...
