Hi George,
Is MAPI over HTTP enabled in the Exchange Organisation? In that case it is currently not possible to open other user's mailboxes, This seems to be a known issue for the Outlook 2013 MAPI. Try Outlook 2016 MAPI, this worked for me (without using MFC MAPI, just in code). With MFC MAPI I currently get the error message
Error:
Code: MAPI_E_NOT_FOUND == 0x8004010F
Function HrGetOneProp(pGlobalProfSect, PR_PROFILE_HOME_SERVER, &lpServerName)
File MAPIStoreFunctions.cpp
Line 340
You could also disable MAPI over HTTP and use RPC over HTTP again for the MAPI implementation, see e.g https://technet.microsoft.com/en-us/library/dn635177(v=exchg.150).aspx.
The outlook connections status (RPC/HTTP, HTTP, RPC/TCP) can also be shown, see e.g. here
