I'm sending your request to the InDesign forum.
The current process involves taking the artwork to Microsoft publisher and then sending the file from there to outlook with the links. Is there any other way, anyone knows to be able to send the file from Illustrator (or Indesign) to outlook?
I'm sorry, but it simply can't be done without converting everything to HTML. If you can expand on this a bit more and let us know why you need to do this perhaps someone can help.
If you need to do it from Illy, please post your request in the Illustrator forum.
