When I try to sign into my livemail account I get this message.

Unable to send or receive messages for the Live.com () account.

Server Error: 0x800488A6
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x800488A6

What is it and how do I fix it?

I have just updated from W7 to W10 and everything has been a mess since then, if anyone can help I will be forever grateful.
