Outlook 2007 Read from WebDAV

I published free busy info to a webDAV server installed on same machine as Exchange 2007.
When I try to read free busy info from Outlook 2007 calendar, free busy info_does_not show. This happens only with Exchange users. I have IMAP users connected to gmail and their FB info does show OK.
The WebDAV server is set up as anonymous to read and write.

I Wiresharked the TCP session and I get this:
GET /freebusy/exchange1.ics HTTP/1.1
Accept: */*

Open in new window

This user does appear in the WebDAV server.
1. How can I troubleshoot this
2. Would Exchange have any settings that I need to look at?

I don't know anything about the publishing process you have tried to do, but the server is simply saying that the resource you have requested
doesn't exist on the server.  Is there a document on the web that describes what you tried to do, and I'll see if I can think of something that might have gone wrong.

This KB shows the configuration on the client side : http://support.microsoft.com/kb/827775

On the server side, I used this tutorial , but there are plenty other. http://www.commodore.ca/windows/shared_calendar/share_outlook_calendar.htm 
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

Okay, thanks.  The server-side doc only mentions .vfb files as far as I can tell (and presumably that's what you created the MIME type for, too); but in your TCP capture, it's showing a request for an .ics resource.  Do you know where this '.ics' comes from?  Or is Outlook doing it all by itself?

Yes, sorry I added mime type text/calendar for .ICS on the WebDAV server and as I mentioned I see the ICS files in IIS.

As far as I know, Outlook can read/write in vfb and ics formats.
There are 2 ways to publish from Outlook.

1. Outlook calendar properties as this link show. http://support.microsoft.com/kb/827775

2. By right clicking on the calendar and selecting publish to WebDAV and this publishes in ICS format.
Can you find the requests listed in the correct IIS log file (in the W3SVC1 folder)?  Maybe your server's default web site is configured with a host header name that Outlook isn't using.
