I'm having very mixed results in trying to send faxes via Outlook 2003
from an Excel Visual Basic script. The script adds an Excel file as an
attachment (which does end up in the outbox of outlook), then the
email sits in the Outbox for at least 10 minutes before I receive a
failure back.

               The Microsoft  Fax transport failed to deliver the
message to the recipient.
    Not all attachments can be rendered.

What's even more bizzare is that I will open the failed email and
click Send Again, sometimes it works and other times it does not.

I have completed all of the other logic required for this program, but
am having issues getting this resolved.

Any help or guidance would be greatly appreciated.
