I know that OL 2007 no longer renders HTML using IE. This prevents using
HTML forms in Outlook email. I know that by clicking Other Actions, then
Open in Browser that the email can be opened in IE and the HTML form works as
it did in Outlook 2003.

Is there any way to add a button or link within an HTML email that opens the
email in IE directly? Basically, the user would open the email in IE with
one click instead of two.

This question is not for me (I don't mind opening the email in IE with two
clicks), it is for my users (4000). They will always prefer opening in one
click. It may seem trivial, and I know that "The users need to adapt" is one
response. What I would like to know if it is possible.

Thanks in advance.
