Free Busy Information RRS feed

  • Question

  • I am running Exchange 2007 on Server 08.  I have all the patches for windows and exchange applied. I can not see the free busy information of other users in my directory.  BUT only when accessing with http over rpc.  Connecting to OWA works fine, connecting with the client (either Outlook 07 or 2010) through either VPN or LAN is fine.  I was thinking it has something to do with the web services but doesn't OWA use the EWS ??  NOt sure where to look.  Need Help Please.

  • Do you have a proxy in your network for all Internet communications?

  • Yes. OWA now also calls the availability service API which reads free/busy information from the target mailbox, but the procedure is a little difference. Outlook Anywhere client should involve Autodiscover to obtain the Availability Service URL.


    At this stage, please perform the following steps to check whether Autodiscover information can be detected successfully.


    1. While Outlook is running, hold down the CTRL key, right-click the Outlook icon in the notification area, and then select Test E-mail AutoConfiguration.

    2. Verify that the correct e-mail address is in the box next to E-mail Address.

    3. Clear the check boxes next to Use Guessmart and Secure Guessmart Authentication.

    4. On the Test E-mail AutoConfiguration page, verify that the check box next to Use AutoDiscover is selected, and then click the Test button.

    5. Then, please post the Result tab and Log tab here for research.


    Also, please run the following command and post the result here.

  • Try Set-WebServicesVirtualDirectory -identity "CAS01\EWS (Default Web Site)" -externalurl

    Replace the external url with 

    And the -identity where the CAS01 is with your Exch servername, which looks like exch2007.

    You may have to restart IIS after,
