remote Outlook not connecting with HTTPS over RPC

As a result of the screwing around I did with IIS yesterday, I seemed to have broken the ability of remote clients to connect via outlook.

This was fixed by looking at the RPC virtual dir in IIS. The security no longer had "Integrated Windows Authentication" enabled. Toggling this fixed the issue.

To confirm, before I toggled this, I tried the clients with basic auth (which was enabled on IIS) and that did work. Then, to be more secure, I disabled basic and enabled Integrated on IIS, and reset the clients to use Integrated.

All is good again...
