How do I use Microsoft.WindowsMobile.PocketOutlook to read the title of an email?

I want to get the title of an email in PocketOutlook on Windows Mobile.

I do a search on MSDN and find that I can use Microsoft.WindowsMobile.PocketOutlook Namespace - - EmailMessage Class - Subject The property should help me get the name of the email.

But when I write

using Microsoft.WindowsMobile.PocketPC;

      

        
        
        
      

    

the error says the Type or namespace name "WindowsMobile" does not exist in the namespace "Microsoft" (are you missing an assembly reference?)

What could be the problem? And is it possible to get the name of the email this way?
