My client's Outlook/outlook.com stopped delivering emails one week ago (last delivered email was dated 8/9/13) and today is 8/16/13.

I have set up a new profile on another machine, and same result, but even fewer messages are downloaded before it reports 'disconnected'.

I'm not sure if there are server problems - I tried changing the server but it reverts back.

This had been working for several months, and now all of a sudden it just stopped working.

Both of the machines I tested on are Win 8 machines with Outlook 2013.
