This is the dialogue box I see when I try to pull my email from Windows Live Mail for this address.

Unable to send or receive messages for the Hotmail (tedinhalifax) account.

Server Error: 3204
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x8DE20003

Is the Server address the problem?  It only started after upgrading to Win10.
