I have the same problem as you. Did you get yours resolved and how? cm
Apparently, the video was too large to send. The email is stuck in my outbox, still attempting to send. Every time I start up Entourage, it hangs. I cannot delete the email from my outbox because Entourage won't stay open long enough to allow it. I have gone to the progress box at Window>Progress, and I can't "stop all" there either. Any suggestions? TIA.
