Thank you for your reply, Ken. But both your suggestions will not work for me:

1) ConversationIndex - yes, it's blank for a New item; but for an existing
item, it always has a value no matter if you created an item by Reply/Forward
an existing one, or opened an existing item by simple double clicking it.
2) "" or "FW:" - a) is not reliable (either the user can modify it at any
time, or it may vary for different languages); b) again, cannot distinguish
an item created by Reply/Forward from an item (may already has or FW: in
the subject) opened by double clicking.

I may not be very clear. What I really want is the way to distinguish the
items created by Reply/Forward, "which are suppose to be sent out" (quoted
from my original post), from the items opened by double clicking, which just
for viewing or printing or whatever purposes.

If the item is a reply or forward it would have a ConversationIndex property
that isn't null. Other than that you'd have to look at the subject and look
for "" or "FW:" or whatever.

How to decide if an Outlook message is created by New/Reply/Forward in VB?
What I'm trying to do is to list all open outlook messages created by
New/Reply/Forward, which are suppose to be sent out.

Thanks.
