How do we fix issues with Outlook 2010 not updating offline address book consistently?

We have some users on Outlook 2010 and thier offline address books are not updating automatically. In order to fix the issue we are having to delete the local OAB file and let it download a new version.

Can someone let us know how to fix this so that anyone using Outlook 2010 doesn't have to delete the OAB each time a change to the GAL happens? We want to roll 2010 to the Org but surely will not until we have a handle on this issue.

Exhange server is 2003.

    Have a look at this Article :

    1. Add this to a new registry file and/or add to your user’s registry (not system, each user on workstation). Create a text file on your desktop, copy/paste the text below, save, then double click to add to your registry:

    Windows Registry Editor Version 5.00
    [HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Cached Mode]

    The above is for Outlook 2010, but for 2007 and 2003, replace the 14.0 with 12.0 and 11.0 respectively.

    2.If you have and OAB files, you need to remove them. In this folder:
    If you see “Offline Address Books”, rename that folder. Close Outlook and reopen.
    You should now have direct GAL access and updates are immediate.

    Does it work fine with Outlook 2007?

    Check and see if adding the registry key helps.
