Detecting RPC over HTTP connection in Outlook

[Chris]

Does anyone know if there's a way to programmatically determine whether the
current Outlook session is connected to the Exchange server in RPC over HTTP
mode? I was hoping that the GetExchangeConnectionMode Outlook object method
would return a value that indicates this mode, but it appears that this is
not the case.

I know of the MAPI properties (PR_ROH_*) stored in the Global Profile
Section that describe how the RPC over HTTP settings are configured, however
these do not guarantee how Outlook will actually connect (e.g. when on a fast
connection, Outlook may be configured to connect by using TCP/IP).

Thanks in advance,
Chris

Hi

Based on my discussion with an outlook expert, the Outlook OM did not
expose such an interface to get the underlying connection protocol.
To session, it did not care what the transportation do, it just send the
request to the underlying Transport protocol, and the outlook buildin
algorithm will decide the concrete approach.
