My Windows live mail will not send or receive email. This happened before but it was corrected after some help from this community. A moderator changed some settings and a few days later it started working again. 

The error message is 

Unable to send or receive messages for the Hotmail (thomaselliott22) account.

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

Can you help please?

Thanks
