  • Hi Karen,

    When creating the ANR Include Online GAL registry entry, did you create it under the HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Outlook\Cached Mode node?

    The KB article is for Microsoft Office Outlook 2003, Microsoft Office Outlook 2007, and Microsoft Outlook 2010, you can try creating the same registry entry under the \16.0 node and see if it works.

  • Hi Steve - Yes - the registry key is created under - HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Outlook\Cached Mode node as we have deployed it through the Outlook 2016 group policy files.

  • We have added the employee id as an email address (112233@something.com) in our AD accounts.  We have Outlook 2016 running in cached mode and also download the Offline Address book.  When an email is addressed to 112233@something.com it sends successfully but does not resolve the smtp address to the clients name.  I tried deploying this key:HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\Cached Mode with Parameter: ANR Include Online GAL set to (1) per this link: https://support.microsoft.com/en-us/help/831124  - But it does not work, Outlook still uses the OAB to resolve names and does not resolve the employee ID@something.com to the clients name.  I then applied the registry keys from this link: https://support.microsoft.com/en-gb/help/921927/how-to-prevent-users-from-downloading-the-offline-address-book-without-disabling-cached-exchange-mode  - and it does work because it completely disables the OAB.  Is there any way to have the best of both worlds: 1 - Run Outlook 2016 in cached mode with OAB downloaded but use GAL to resolve names when connected and when in a disconnected state be able to use the downloaded OAB files.  Is there a way to add the custom field containing the employee id@something.com in AD to be downloaded with the OAB files so Outlook will resolve the address to the clients name??

     update - I opened a ticket with Microsoft and the resolution was to completely disable the OAB per this link :   https://support.microsoft.com/en-gb/help/921927/how-to-prevent-users-from-downloading-the-offline-address-book-without-disabling-cached-exchange-mode
