Original Title: Problem in WLM with an email address

I have several email addresses in WLM and all are checked automatically for incoming mail. One address (the default address) will not receive. I get a timeout with "POP3 server not responded. Error ID 0x800CCC19" The dialogue box says that it is trying to download one of five messages. However, I set up the same email account on Thunderbird and it says there are no messages to download. I can also go into my mail account on the web and it similarly says there are no messages waiting on the server. If I uncheck this address for receipt of mail, WLM works perfectly. I have tried deleting the account from WLM and re-installing it but that makes no difference. I also made sure Windows Essentials was updated. What is causing this problem?
