I keep getting this error message :

Unable to send or receive messages for the angie.dangelo (O) account.

Server Error: 4201
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x8DE00002

It's weird because my other 'outlook' email account is working fine, any hints?

Thanks
