I would like to use Exchange e-mail groups as an authentication scheme for an internal app. IE, if a user is in a certain mailing group, they are allowed in.
Any pointers on where to look for information with talking with Exchange from .NET?
EDIT: Exchange 2003.
You don’t need to talk to Exchange itself. All of the data is stored in Active Directory which has very simple to use APIs within the .NET framework. Exchange e-mail groups are stored in AD as global distribution groups. All you need to do is ask if the user is a member of a specific group.
