All my mails do not come into my Live mail. Gives me error continuously;

Unable to send or receive messages for the account. Server Error: 0x80048820 Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx' Windows Live Mail Error ID: 0x80048820

Please assist to solve this problem. I have not been able to receive emails for days. I now go through the browser, which can be cumbersome checking old and new mails. Thanks.
