By using an offline address book, Outlook doesn’t have to connect to Microsoft Exchange Server to resolve names or open the records for each user.

Note: If you're using Cached Exchange Mode, we recommend that you download the full details of the offline address book.

This reduces the number of times the Outlook window might become unresponsive and the number of unnecessary connections to the Microsoft Windows Server Active Directory.

After making changes to recipients/distribution lists within Exchange, I sometimes required a way to make these changes quickly accessible to users, so when they next download the GAL through Outlook, they obtain the latest changes.

Most environments do this automatically once or twice a day, which is fine, but this script can be used to force the process to run as required.
