I think I'm the first one to report this issue in 2015!!!

I began to have this problem since last tuesday:

Server Error: 4201

Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x8DE0000

• Check Date and Time Settings on the computer : DONE!
• SSL security DLL libraries may not be properly registered: DONE! (Although I couldn't find the initpki.dll)
• Delete and add my account: DONE!
• Repair Windows Live Essentials: DONE!

I have Windows Live Mail 2012 (16.4.3528.0331)

Windows 7 Ultimate 64bits with SP1

Can someone offer some help to solve this problem?
