RE: Outlook connection with MAPI to front-end server

Direct MAPI will not work.  I have not tested whether or not it just fails, or 
if it is smart enough to try and redirect the client to their back-end server.  
:)

The RPC over HTTP does work, so if you are wedded to Outlook connecting to your 
front-end server via the Internet, you'll need to dig in and troubleshoot RPC 
over HTTP (hopefully https, but that's just adding an SSL cert to the virtual 
directory).

If we can help with the RPC over HTTP, let us know.

Unless your front-end server is an RPC over HTTP proxy, it won't work, because 
you don't have any mailboxes there, right? 


Correct! No mailboxes. But I was under the impression we could connect with 
regular MAPI on the front-end servers. Anyway, I originally tried using RPC 
over HTTP without more luck. That is what lead me to try direct MAPI.

Thanks!

Hi!

I am having a problem connecting with Outlook (MAPI) to front-end servers. It 
can not resolve the username. There is no firewall between the front-end and 
back-end servers (the front-end servers are used for load balancing).

I can connect to the front-end servers using POP or OWA no problem. Just does 
not work with MAPI.

I have not done any registry changes regarding ports since there is no 
firewall. Maybe I am in error and I must configure the registry to map the 
ports?

The back-end server IS NOT a DC.

Any insight would be very appreciated :-)

Fred
