Enabling Kerberos Authentication

We had a customer recently who was using Outlook 2010’s MAPI in their application to talk to the Exchange server.

I thought I’d fill in some details. For starters, this error has nothing to do with WSAECONNRESET, which…


September 2011 Release of MFCMAPI and MrMAPI
