Question

Could you tell me " how to Send email using the remote Exchange server referred to in the Inbox profile"  (default mail client) in Windows application in Visual Studio 2005.

This could be done using MAPI controls (MAPI Session, MAPI Message) in VB6.

And also tell me equivalent to MAPI controls in .net.
