Hi Sue,

I believe I'm already using the "One-Off Addressing" format they suggested.

I'm setting the recipient properties like this:

PR_EMAIL_ADDRESS :
PR_DISPLAY_NAME :
PR_RECIPIENT_TYPE : MAPI_TO
PR_ADDRTYPE : SMTP

Does that seem right to you, for the "SMTP address" format? I believe that
the other format of "[SMTP:SMTP address]" would be something like this:

PR_EMAIL_ADDRESS : ]

Thanks,
Mark

Did you try the different address format suggested?

I'm using MAPI to send an email with my Outlook add-in. Sometimes the
emails are sent with a winmail.dat attachment when sending through an
Exchange server. I'm trying to figure out how to prevent this from within
my add-in? I've read this:

http://support.microsoft.com/kb/138053

but in my case I'm adding the recipients dynamically, and they aren't in
any
address book. I also don't have control over how they've configured their
Internet Mail Connector (IMC).

I'm wondering if any of these will help me?:

PR_SEND_INTERNET_ENCODING
PR_SEND_RICH_INFO

Any tips would be greatly appreciated.

Thanks,
Mark
