  • Out Of Office not working (Again & again)

    Hi everyone, sorry if this issue has been posted (and resolved) several times, but after hours of googling I am still stuck with it and it's really frustrating !

    I'm completely new to Exchange 2007 and taking over a project of someone else, i.e. it was not me who did the whole installation...

    The problem is, as you can imagine, when a user clicks on Out Of Office Assistant, he gets the famous:

    When now I try to ctrl-right click on the outlook icon and test email autoconfiguration, it tells me that it cannot discover any settings, and here is the output of the log tab:

    I really don't know if the guy who installed Exchange did it correctly, but the fact is that I don't have the necessary knowledge to troubleshoot this issue.

    Really hope you guys can help me sort it out...

    Feel free to ask for any other information...

    In several cases it was a proxy server set in Internet Explorer which prevented users from reaching the Exchange webservices.

    You might check in this, some people forget to exclude internal IP ranges from proxying and for some reason Outlook is still using proxy settings from the Internet Explorer.

        Is that name included on the certificate for it?

            The reason why OOF is not working because Autodiscover is failing and due to this even free/busy as well OAB will fail.

            So try below steps and post the output:-

            a) Try browsing SCP url i.e. https://iorecexc.iorec.local/autodis...todiscover.xml

            b) Whats the IIS version you have on CAS?

            c) What's the authentication method set on the Autodiscover virtual directory?

            d) also run GET-exchangecertifcate |fl on Exchange powershell and post the output.
