When trying forward an email message with a 13 MB attachment, it never sends and I receive the error -
Cannot send mail
An error occurred while delivering this message
Email is on an Exchange 2007 server and active sync policy has attachment size as unlimited
I am also seen event ID 1008 - exception occurred and was handled by Exchange ActiveSync. I removed email from the phone, removed the partnership on the server and disabled active sync for this user. I then enabled ActiveSync, added the email account back on the phone and it is still not working.
