I'm using Windows Live Mail for my e-mail account, but WLM can not do send and receive recently. First it was executing "Updating calendar" countinuously, but now do not go to "updating calendar" but after some seconds one error appears as:

Server error: 3204

Server: https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx

Windows Live Mail Error ID: 0x8DE20003

What should I do?
