Posting a specific question, as had posted a similar question, but was general question about editing profile details.

A Windows Live (Messenger) profile had "Other Address" details (i.e. not home or work) added at some point in the past. Not sure how this was added, whether through the Social Connector feature in Outlook or the old Messenger Client. Cannot now get rid of this information.

How can this be "cleaned up" from the account?

There must be some way to get this resolved, even if it requires a call to the Microsoft help desk.
