hidden message

[Software Solutions]

I want to create a hidden message in the user's inbox so that I can store
some information to be used by my COM Add-In. How do I go about this without
using CDO?

You can't do that with the Outlook object model. You would have to use CDO
1.21 or Extended MAPI or Redemption (www.dimastr.com/redemption).

mmm..the reason I do not want to use CDO is the issue with applying security
restrictions to CDO. Is it possible to trust a specific DLL's use of CDO,
while locking down CDO access for all other clients?

No. CDO 1.21 is never trusted (client side) unless you specifically trust it
in the Exchange security form. I usually end up using a combination of CDO
and Redemption for things that aren't exposed to the Outlook object model.
In cases where I don't need access to InfoStores or anything above the Top
of Information Store folder I don't need CDO and just go with Redemption.
