One of the advantages of RTF mail is that it supports
inline attachments - you can attach a file and have it show up anywhere in the message,
rather than in the 'attachment well' like it does with HTML and plain text messages.
You can actually achieve a similar level of functionality with HTML mail. This
tip works in the last couple versions of Outlook, although there are some quirks.
1. Create an HTML email message and address it to yourself
2. Attach a file, foo.txt for example
3. In the body of the email message, type foo.txt
4. Highlight "foo.txt" and go to Insert | Hyperlink
5. In the "URL" field ("Address" field if Word is your editor), type the full name
of the attachment plus extension (foo.txt in this case)
6. OK out of the dialog
7. Send the message
When you receive the message, you will be able to click
on the link in the body and open the attachment.
