I have followed all types of advice so far, but when opening my Windows Live, the accounts starts to receive emails then stops abruptly with the following error:

Unable to send or receive messages for the Yahoo (uxl2001) account. The email server returned an error.
Server Error: 0x800CCC90
Server Response: -ERR [SYS/TEMP] problem retrieving message.
Server: 'plus.pop.mail.yahoo.com'
Windows Live Mail Error ID: 0x800CCC90
Protocol: POP3
Port: 995
Secure(SSL): Yes

I have verified all server settings, updated everything and cannot get what is a very much, daily use program..  Any help would be greatly appreciated!

Thanks
