Windows Live Mail Error ID: 0x8DE20003

I was recently updated to Windows 10 and have this message on 3 live.com email accounts but not on my default live.com email account.

Error message is

Unable to send or receive messages for the Live (sbosullivan) account.

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

I have followed all steps mentioned in varies posts except uninstalling Windows Live Mail 2012 and re-installing.

The synchronisation message is on each of the three accounts permanently.

Any help would be appreciated.
