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

I have 4 accounts loaded in Windows Live Mail v2012 - 2 of them are live.com accounts - all 4 were working correctly in Windows 7 before I did the Windows 10 upgrade - the two live.com accounts are set to the HTTP mail server  "https://mail.services.live.com/DeltaSync_v2.0.0/sync.aspxat"   - I am now getting the above error message on the live.com accounts, but the other 2 are still working properly - I am not logged in to any account - I am suspecting that this server setting may no longer work???? - I have already tried the Microsoft Fixit program (no help) -  any help on resolving this to get these two accounts working again will be greatly appreciated
