I'm using Windows 7 Ultimate and Outlook 2007. Recently, I've become unable
to successfully forward messages in Outlook 2007. When I attempt to do so, I
receive a mail delivery error. It also occurs if I attempt to copy and paste
the message information from the e-mail that was returned with the error into
a new message and send.

I can send a new message just fine. I can send a message with large file
attachments just fine. I can reply to messages without problems. My only
problem right now is with forwarding.

Any ideas?

Thanks.
