Managing personal Outlook.com account settings, security, and privacy
All this information gathering is totally unnecessary. If Hotmail worked without problems with what ever browser was being used and Outlook does not, then the problems are due to changes made by Microsoft - not by its users.
I've used the same XP pc to access Hotmail (3 accounts) for the last two years with few problems and not one instance of the "We can't connect to Outlook at the moment," message.
My advice, stop asking questions; you made, you fix it. And next time you make changes, fix it before you throw it into the ring.
In any reply, please post a link to the "Claims for Outlook Software Testers" page so that I can send in my claim.
