Hoping to get this question answered becuase it just doesn't make sense to me.
I have a lab set up and doing some testing with Exchange 2007 SP1\SP2 and Exchange 2010.
When I launch mfcmapi and try to connect to a mailbox I get a MAPI_E_FAILONEPROVIDER == 0x8004011D.
Now then as soon as I create a Public Folder store on the exchange server where this mailbox resides all is happy with the world and I can open the mailbox.
What am I missing here. By what I see mfcmapi requires a PF store to work. Is this actually the case?
