Windows Mail problem

  Gwynedd 12:03 30 Nov 09

When my wife opens Windows Mail she gets an 'cannot send' error message 'Invalid address - server error 553, No, error 0x800CCC79' window on her Windows Mail page

There are also no categories - Inbox, Outbox - on the left hand side of the main page. It is just blank.

My Internet provider -NTL - has reset all my settings but it still won't work. They say it is a software problem, but MY account works perfectly well.

Any suggestions other than a trip to my pc workshop.
