This reduces network traffic and improves performance.If Outlook is left running constantly in Cached Exchange Mode, it updates the Offline Address Book automatically about once a day, depending on Address Book updates on the server running Exchange.
If you use Outlook with an Exchange Server account, your address book list will include the Global Address List (GAL).
So to force your Outlook to sync with the Exchange server you can manually update the GAL.
When connected to an Exchange server, Outlook will automatically synchronize the address book once every 24 hours.
