Retrieving custom headers from an Outlook (2003) MailItem

[Andrew]

Environment: Visual Studio 2008
Language: VB.Net
Application: Outlook 2003

I seem to have come to a road block. I'm writing an application that needs
to get the header from an email in Outlook 2003. This needs to check every
existing mail that's opened.

One of the ways I found that could get the header was to use the CDO libary,
however, I also found that Microsoft doesn't officially support its usage
with managed .net code because of memory leaks. The work around was to create
a separate exe for the CDO functionality.I'm not sure how efficient that
would be since it needs to run everytime an email is opened.

Is my fear of it being extremely inefficient warranted? If so, is there a
plausible work around?

Thanks,

Extremely inefficient, and also a source of memory leaks. You're logging
into and off of CDO.Session objects on each call?

For managed code and Outlook 2003 your options are limited. You can do what
you're doing now or you can use Redemption (www.dimastr.com/redemption) or
another API that works with managed code.
