I would use the newer mail components in .NET, instead of working with
Interop. This should solve your problem.
If you have to use MAPI, did you create a reference to the COM component in
your project?
NOTE: There is an open source project ExtdSmtp at
www.sourceforge.com that
you can download and compile (C#) that is a fairly nice SMTP component. I
realize SMTP and MAPI are two different things, but I took a chance that
sending mail was the primary need.
