Possible to send "X-Header" or equivalent along with a MeetingItem?

I need to send some hidden data along with certain MeetingItems I create in my application. I have managed to successfully test creating X-headers to do the same for regular email messages (Thanks Sergey..).
Is it possible to do this with a MeetingItem as well?

Note: This is for a mixed - Exchange + SMTP server environment.

Hi Don.

I think it should work properly because all Outlook items implement the IMAPIProp interface.

X-header tests...

I downloaded and re-built the OlXheaderExample project successfully in MSVS 2005.I registered the ADX project and ran my Outlook (2003) client.

case #1 - When I send a message to a user having a Outlook client on a local Exchange server, he gets the X-Header(s) embedded in the message headers ok.
case#2 - When I send a message to a user having a Outlook client that is connected an account on a SMTP server, the X-headers vanish.

Has anyone done this successfully? Am I missing something?
Sergey - Could someone verify that the OlXheaderExample code does indeed work (in case #2) (and let me know) before I spend more time on this?

Thx - DH

Hi Don.

The example doesn't work in case #2. The fact is that Exchange server removes all x-headers before sending emails.
