I've never seen this one before. I'm troubleshooting this right now. This is Outlook 2000 SP3 configured with a single POP account and it's been working fine until suddenly today this employee, Jenny, calls me to tell me that emails are not exiting the Outbox yet they're being sent. I remoted to her PC and sure enough she's right. anyone have any ideas what the fix is for this? I've already tried disabling COM Add-ins with no luck so far and we've rebooted, started Outlook in Safe mode, and I'm about to do a Repair on Outlook right now. Thanks!
