For the past week or so I've been receiving the following error message on Windows Live Mail:

Unable to send or receive messages for the Hotmail account.

Server Error: 3204

server: "https://mail.services.live.com/deltaSync_2.0.0/Sync.aspx"

Windows Live Mail Error ID: 0x8DE20003

I've tried opening and closing the program, restarting the computer,  deleting and adding the account,  and installing the latest version of Live Mail. Nothing is working. Could you please assist me?

Other info:

-  No issues with syncing mail on my smartphone or accessing it through the Microsoft Live website

-  Syncing status on live mail repeatedly attempts to update my calendar 

Thanks for the help.
