This has only just happened, and it never happened before. The querk is, I can send or receive e-mails no problem in Outlook Express. So why can't I use Outlook now? I'm using Outlook 2003. Let me emphasize, I've never had this trouble until just. Thank you, and I look forward to hear from you all.
