Have you gone to the server and cleared it? There are web email services around.

It sounds like you have tried more things than I knew to try, so I am not
sure what to say. Here are some guesses...

Earlier in the thread you mentioned that you installed Office 2007, and then
went back to 2003. It is my understanding that only one version of Outlook
can be installed at a time. This would mean that your Outlook 2003 was
overwritten, removed or changed significantly. I would make sure that you
had uninstalled Office 2007, and then I would reinstall Office 2003 or at
least Outlook 2003 and Pub 2003. I don't work with Outlook, but it would
seem that you should be able to backup your message store before you do
this. You can opt to leave copies of messages on the server with Outlook
Express...I presume the same is true with Outlook. Change that option and
once you download, the messages shouldn't download again. You might want to
post the question of how to reinstall Outlook 2003 after installing Outlook
2007 trial, and keep all your settings, messages etc., in an Outlook
newsgroup, if someone else doesn't jump in. As I said, I just don't work
with Outlook.

With that said, you might try changing the default email client to Outlook
Express and see if you can email that way. From my limited testing, I have
been able to send as a message through OE with Pub 2003 and 2007. Even the
act of changing the default, and then changing the default back, might help.

I understand Mary's concern about HTML formatted email, and agree that it
has more inherent risk, but like you I find that most people do have in
enabled. Computers come with it enabled, and I don't think most people ever
change that. In fact I don't think most people change many default settings
in any program. But given that there is indeed more risk with html, I
understand that MSFT did change Outlook 2007 so that it is safer and more
limited in what it can do. What I am saying is that even if you do get this
figured out, there is a movement away from the old ways of sending html
formatted email, and ultimately you will need to find another solution
anyway. Furthermore, even if you do figure out how to send your email as a
message rather than as an attachment, your next post will be why the email
doesn't look right...why it doesn't work for AOL people...why things shift
around, why the formatting doesn't work etc. I think the people that have
got this feature to work in Publisher have had to simplify their email
messages so much, that most of the reasons to compose the message in
Publisher and send as an html message are gone. That would suggest a
compromise to me.

As Mary suggested, perhaps design a more basic html formatted message in
Outlook, that introduces people to the subject and tells them to open the
attached PDF file. Converting most of your Publisher content into a PDF file
and attaching it will be your easiest solution for working around the
formatting issues of an html formatted message. If you write the intro well
enough, then people will open the PDF. If your intro is not good enough to
create interest, then it won't matter if the content is attached or in the
message...they still won't read it. Note the email templates in Publisher.
Almost all of them follow this philosophy...there is an introductory
paragraph followed by a "read more" link to more content on a website. This
is the "best" way to do it in my opinion, but if you don't have a website,
then the second best would be "read more by opening the attached PDF file".

A lot of words for someone who didn't know what to say...hope you work it
out.
