I know that there have been issues with outlook/Hotmail (and by the look of the community messages so are lots of other people still) and I read that these issues have been rectified and now according to your service status all system are "running normal".  BUT I am having issues (have been for the last 2 days) Mail app on windows 8 keeps coming up "couldn't sync messages", I have uninstalled and reinstalled and still not working with my Hotmail account. Thru frustration I signed up for a Gmail account and added this to the mail app in windows 8 and it works perfectly? So I don't have a problem with the app or my computer. I am also experiencing the same issue with iPhone and ipad and I have also deleted and reinstalled Hotmail account but still experiencing issues (added Gmail and it works perfectly also).

I have been having intermittent connection & sync issues with outlook 2013 (same Hotmail address) on my computer over this period as well, but cant rely on this at the moment.

There must be an issue with my individual Hotmail account service, and from what I am reading I am not alone.  I require this to be fixed and require a Microsoft support person to investigate and come back to me with a solution/fix.
