  • Issue With OWA

    Hi,

    Wondering if anyone can help me i have recently installed and configured Exchange Server 2003.......It is installed on a Windows 2003 Server with Service Pack 2 installed and all of the microsoft updates installed. Exchange Server 2003 version 6.5 ( Build 7638.2: Service Pack 2 ). I have created a new Global Address List and set relevant deny permissions on the original Global Address List so now specific users can now only see my new Global Address List, this works fine with Outlook 2003 for the specific users and i get the desired effect........but when the open up OWA they can still see the original Global Address. I would ideally like the specific users to use the OWA but not be able to see the original Global Address List, is there a way i can accomplish this goal? Any advice would be greatly appreciated.

    Regards, Yzahjh.

    I suppose i should get the specific users to use Outlook 2003, really racking my brains though as to why when using Outlook 2003 they can see my newly created Global Address List which is fine because i have denied the specific users access to original GAL.......but when using OWA they can access the original GAL....is it because OWA doesn't rely upon the permissions....seems weird just can't get my head round this one.

      We have a similar problem with cached mode Outlook. After researching it we found that Outlook in cached mode will always download and use the original default GAL (while it's in offline mode) regardless of the permissions. Maybe OWA has the same problem. If I remember the article we found I'll post it back here.

        If that was the case, then how would hosted Exchange providers operate?
        They support cached mode and do not give you the entire GAL.

        This sounds like either the permissions have been applied to one or other of the Offline Address Book and the GAL, and not both.
        You need to have a matched pair of GAL and OAB for everything to work correctly.

          Simon, we are a hosting provider and I'm speaking from first hand experience. We had followed all the best practice configurations regarding this and couldn't get it to work. We finally opened a support case with MPSS and they couldn't make it work either. If you know a method for making it work, please point me in the right direction as I'd like to get it fixed. Thanks much.

            So does the OWA use the Offline Address Book then ? If so can i select the Default Offline Address list properties remove the Default Offline Address list and then add my new GAL to it and apply that, would that then give me the desired effect ?

              I haven't built any hosted Exchange environments, but I have worked with a few.
              All of them allow a unique GAL for each virtual org, including OAB. I don't think it would be very good for the hosting providers to provide anything else.

              Unfortunately the hosting providers don't tend to share their secrets - it is a cut throat world. The most active from the hosting world in the Exchange community is Michael B Smith, who was one of the authors of the Exchange Server Cookbook for O'Reily.

              Surprised that Microsoft were not able to resolve the problem.

              OWA does not use the OAB, it uses live information.
              The common mistake is trying to use the default GAL for anyone. What I have been told is the block access to the default GAL for all users and then replace it with custom GALs.

              Simon.

                  Well, I wish I could figure this out in our environment. We've tried a custom Default GAL, permission restricted GAL's, removing the OAB folders from the system public folder tree, and tried every article and google thread we could find. After speaking to MPSS we finally gave up as we only have a few of our hosted customers who use Outlook in offline mode. If I ever do find an answer I'll post it here.

                  As for the "live" GAL's and the OAB's we do provide custom ones for every hosted customer as well as the requisite custom Recipient Policy for each hosted customer. We're currently at about 75 hosted customers as well as providing BlackBerry, GoodLink, and MSExchange Activesync.

                    We finally figured out how to do this. We created an OAL based on the address list in the All Address Lists container instead of the GAL in Global address Lists and it works.
