Microsoft: Unable Remove Additional Mailbox in Outlook

<< Problem >>
You have given yourself full access rights to an user's mailbox. But now, in your Outlook, you have their mailbox and you cannot remove it. Their name does not appear in 'open additional mailbox'.


<< Solution >>
You need to go into ADSIEdit.msc, Domain context, and drill down to the account you wish to be removed from, and look for the "MSExchDelegateListLink" attribute and remove yourself from that list.  The next time you start Outlook, the ghost "additional" mailbox should disappear after a few minutes.
