Hi folks, here’s an issue you might run into and tear your hair out over. If you have a BES server working with Exchange and are using multiple GALs (Global Address Lists) in your environment, how do you setup the BES service account to access all the users in the different GALs?
Well the first thing that usually goes wrong is that you can activate everyone but you can’t get certain things such as appointments to sync correctly from the BlackBerry device to Outlook. This is because BES can only look at one GAL. That’s right, you heard me correct, only one GAL. Don’t fret, there is a way around this.
Create a third GAL that incorporates a filter that lists all the users of the other multiple GALs. This way you have one GAL that covers everything. Then give the BES service account permissions to access that GAL. Also make sure you add the Exchange Domain Servers Group full access to the GAL as well. Then in offline address lists you can add that GAL to the offline address list as well. Then don’t give access to the BES service account to the other GALs. This forces the BES service account to only use that one all encompassing GAL you just created.
Then go into your BlackBerry server and when you go to add a user to the BES server you will notice it is seeing all the users from your multiple GALs. That’s it, hope that helps!
