Hi Sue,

Thank you for that information. I know it is confusing and I'm not making it
any clearer. When I said I dont mind showing the original message on preview
window, I wanted to make a compromise. It's ok to show the original contents
on preview but atleast the user will see what I want him/her to see when the
message is opened. However I'd be happier to show my messageY on messageX's
preview window if it's possible. But I can live without that part as long as
I can show the messageY when user double clicks on messageX and opens it.

I know I can use Item_open on a custom form to call whatever functon to do
this. Now my questions are;

1.) Can I retrieve messageY in Item_open event and show that as opposed to
showing messageX? If so what's the command to retrieve a message?

3.) If I opt to custom forms, I'd have to publish it into Organizational
Forms Library to make it avaiable to all Outlook users, but how can I enforce
the Outlook users to use that form?

Thanks
Duke
