Outlook 2003 Users in Cached Mode Do Not See GAL Updates Unless You Manually Delete OAB Files and Edit Registry

We are having a strange problem with our Outlook users who are using Outlook in Cached Mode. The Global Address List does not accurately reflect additions or subtractions of users even after 48 hours and manually updating.

After troubleshooting the problem, I found the problem to be only with users who are using Outlook in Cached Mode because users that are not in Cached mode see the changes instantly once I refresh and rebuild using Receipient Update Services.

The only way I can get Outlook Cached Mode users to see this change is to go through the tedious process of deleting all of the *.OAB files on their computer, and also adding the following registry entry

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Cached Mode]

It just seems like there is something buggy or wrong here.

    Are you on an older version of Outlook by chance, that may need some patching?

    The registry key simply stops the client from downloading the GAL - it uses live information instead. That doesn't actually fix the problem.
    I suspect that your OAB is not generating properly, or there is another problem with the OAB distribution.

    Therefore the first thing I would do is attempt to force the OAB to regenerate and look for errors and also check that the OAB system folders have a content count that is not 0.
