I am having a problem with Microsoft Outlook 2003. Emails are getting stuck in the outbox intermittently. The quick fix that I have been using is closing out of Outlook and reopening after a short pause. Sometimes this works and sends the emails in the outbox. If this attempt does not work, I have to end the outlook.exe process in the task manager. Then resend the emails in the outbox. I'm wondering why this keeps occuring.
I'm not sure if it is the Email Server, Anti-Virus Software or Outlook itself that is causing the issue.
