Outlook 2007 on Exchange 2003 SP2 cannot see free/busy information for some users.
I spent all day yesterday researching this site and others for a solution to this problem with no luck so I am asking for help. We have a mixed environment of Office 2003 and Office 2007 and are using Exchange 2003 SP2. Our Outlook 2007 users cannot see free/busy information for some users. What we see are the "\\\\..." No Information. The Outlook 2003 users can see the free/busy information. I had a few that were showing no information in Outlook 2003 but I had those users run the /cleanfreebusy switch and those are fine now in 2003. I tried setting up a DNS forward lookup zone for "autodiscover.domain.com" and pointed it to the A record for the Exchange server. The instructions I used were a bit sketchy so I'm not sure if I did it totally correct. It still does not work. If I do the "Test E-mail Configuration" and uncheck Guessmart and Secure Guessmart, using only Use Autodiscover I get this in Results:
Autoconfiguration was unable to determine your settings!
In the Log section I get an error:
Autodiscover to https://autodiscover.domain.com/autodiscover/autodiscover.xml FAILED (0x800C8203)
Yesterday I was getting more errors but didn't write them down or screenshot. I think they were (0x80004003)
I am not expert at DNS or IIS but I cannot see a virtual directory in IIS6 for autodiscovery.
Please help. I need to resolve this so we can schedule resources and have everyone see them.
