I've been trying to play around with IIS and my Exchange 2007 server because I cannot access Automatic replies from Outlook 2010, so one of the many articles I have tried to use is this article

One of the things about authentication methods for the EWS virtual directory. The only thing that should be checked is "integrated Windows" should be checked, so I had to uncheck Basic Auth checkbox. I did that hit OK, then apply. I ran iisreset, then checked outlook to see if that fixed my problem, which it didn't. So I went back to the EWS directory to check the auth methods again, and the "Basic Auth" was checked again.
How do I keep the system from checking that box, if I uncheck it?
