For the last 3 or 4 days I have received error messages as shown below (please note, I have deleted my actual email address for security purposes).  My Outlook will not sync and says "Limited Connectivity".

I can access all emails ok when logging in directly to my Hotmail account.

Microsoft customer services are unable to help and have suggested I post to this forum.  It is a bit worrying when they cannot recommend how to resolve the problem so hopefully some technical expert out there can, please?  In plain English would be a huge help please.  Thank you
