RPC/HTTPS connections to multiple servers

I notice when my OL client connects via HTTPS that I see multiple directory and mail connections to the exchange server.  This varies from client to client- and some clients also connect to multiple exchange servers, I've seen as many as ten connections and as few as three. Is this the most efficient communication possible or do we need to tune it?  I can see several simulataneous connections to my home exchange server as normal- but connections to additional exchange servers?  (I verified using pfmigrate that the public and system folders are identical on the servers).

Do you have multiple Exchange servers on the site? If so you should be using a frontend server.
I usually see four connections - two for the mail and two for the directory. Haven't seen more than that before.

Are all the connections to the same server?

Hi Simon-

Yes, multiple backend exchange servers- single front end that handles the rpc proxy/ssl.  All the connections are usually to the same server (for example right now I have 8 connections, 3 directory and 5 mail), however the client I was referring to above also has a mail connection open to ANOTHER back end exchange server.  I was thinking maybe it was a public folder, but pfmigrate says they have the same folders.  It seems to work fine- about twice a week I get a "lost connection to the exchange server" popup from the OL systray icon- but it always immediately reconnects.

Is the Outlook installation accessing multiple mailboxes?
I haven't got access to a multiple Exchange server site at the moment, so cannot check what happens on a known working site.

Brilliant Simon! The user had added another mailbox, which was on another server.
