How can I remove access to another mailbox in my Outlook

Hi, about 6 months ago I needed access to another mailbox and I added it by going to File - Account Settings - Change - More Settings - Advanced. Now I need to remove it, but when I go there, I can't see anything, the name doesn't appear!!! I tried to say "Close Mailbox" but it tells me I have to do it through Account Settings!!! I have Outlook 2010, and I connect to an Exchange 2010 Server.
Can you please help?

Remove the permissions from the mailbox and it should be removed by the Autodiscover process.

This is the automapping feature at work:
