Had a photo go missing from my Flickr photostream so changed my Flickr password and my Hotmail password.  Next time I went to log in to my Hotmail account my new password was refused.  I went round in circles trying to resolve this with the Microsoft options available to me.  Eventually set up a new Outlook account, and notified Microsoft support of the problems I was having.  When I went to log in to my new Outlook account today was not able to and the message over the account log in box was 'account doesn't exist'  (even though had been using account last night!)  Was able to log into Flickr last night will do so later, assuming I can.  Have no idea what is going on - very frustrating and time consuming - not had any problem like this before.
