I am using SendNow with Outlook 2010. Can you help?
How large is the file you're trying to send? Are you trying to send more than one file with your email?
Hopefully with a bit more information we can get this resolved for you.
I deleted the file but can tell you it was no more than 10MB and it was only one file. I would rather use this product through Outlook instead of the Adobe SendNow Desktop Icon.
What type of file were you trying to send? This document outlines what file types may not be sent: http://forums.adobe.com/docs/DOC-1521
If the file you were sending was allowed, did you try sending it through the Desktop App or the web interface?
