Custom Save as file type in Outlook 2003

Hi,

I am Eric with Project Control Engineering, Inc. I was wondering if it is possible to set a default file type that files will be saved as when you clikc "save as" the default now is "Text Only (*.txt) or as appears to be based on the e-mail file type.

I want to be able to set it to a default file type so I won't have to select the file type I want, my employees only need to save as one type and often forget to change the file type.

Can this be done wtih VB.NET, C#, or C++?
Where is the source for the "Default" filetype located or drawn from?

Thank you,
Eric
