store.log is rarely useful and wastes a lot of Disk IO. You can erase
this line to gain a bit of speed.

  * login=PASS uses Basic auth protocol. Check that Exchange is
configured to match.

NP: for something more secure 3.2 can do login=NEGOTIATE for Kerberos.

You may also be able to use "login=PASSTHRU connection-auth=on", but we
have not checked that yet with Exchange.
