I started having problems with my hotmail account today, first not receiving emails, then not allowing me to send them, and finally it sometimes won't let me log in. It keeps saying - 

Sorry, outlook wasn't able to complete this request, or Sorry, there seems to be a problem with your account.

Another hotmail account has logged in from the same computer so its not a problem with the computer, and I can't log in on other devices either so it's a problem with the account.

We have a Mac computer with OS X, and I tried rebooting, rebooting the modem, reseting Safari, and I tried to remove my cache as per instructions for Safari for OS X but there is no option on my computer under Safari for Remove Cache, so I followed the instructions for the Safari for Microsoft and Reset Safari, and removed all website data.

Therefore I think there is a problem with my hotmail account / now Outlook?

Please help?

Kind Regards
