This is not the issue......my outlook does the same. My ISP allows
up to 20 mb e-mails but any attachment over 1mb has been sent
multiple times. The e-mail goes to the outbox where is seems to syc
over and over. I sent a test to someone who stated they received
over 30 e-mails and my "sent" folder did not indicate that it had
gone once.

So have you done what's been suggested already?
