That looks thorough. As a test, could you put two buttons on a form each with same code, try one, then the other, back and forth a few times, see what happens?

Also, one thing that's changed a couple times is the Send function. I've had to alter my Send to include parameters (first) or different parms (later) at least twice since I've upgraded Outlook versions. Could be related, possibly...
