I have multiple email accounts in Outlook 2003, 5 out of 6 of which work fine. The 6th has been having an error for weeks 'Outlook is unable to connect to your incoming (POP3) e-mail server. If you continue to receive this message, contact your server administrator or Internet Service Provider (ISP).'

Well, this morning i had to start outlook in safe mode (Not even sure why I had to do this), and all of my emails from this account downlaoded. I then closed and opened regular Outlook, error is back. Closed and opened in safe, it works. Regular- does not work. Any ideas how to fix this or what could be the cause? I don't want to have to open in safe mode every day to check this email?
