Yes mine was the same. I got mine working again by going to Tools, accounts and then under properties i altered the POP3 settings title from pop.wanadoo,co.uk to pop.orangehome.co.uk.
Did the same with the SMTP line. This worked for me EVEN when using System Restore did not.
PLEASE do not attempt this if you are unsure about changing it as i do not want to be held responsible.
Cheers Darryl
