Outlook won’t send email, it just sits in your Outbox
Ok, so first if you also can’t receive email, this isn’t your problem. This is about a send only problem. I could receive email just fine.
If your problem matches the helpful description here: http://www.slipstick.com/problems/outbox.htm
Also a similar article on Microsoft’s official Office support site here: http://office.microsoft.com/en-us/outlook/HA011879881033.aspx
Then you have the same problem I did. I wanted to specifically mention that it was LANDesk Antivirus causing the issue as that hasn’t (so far) been listed as one of the Outlook add-ins that causes this issue.
The registry key I had to modify was here:
This was installed with LANDesk Antivirus and is identified with the FriendlyName of "LANDesk Outlook add-in" and Description of "Scans email for viruses" (all items a user could search on.) I'm running version 188.8.131.52 which I believe is the latest.
Once I set LoadBehavior to 0 it solved my issue.
Big thanks to Diane Poremsky for writing the post linked to above which helped me debug my issue.
