The Offline Address Book (OAB) for Exchange users is generated immediately when your account is created. However, it becomes available only after maintenance tasks are completed on the Exchange server (usually around 5:00 AM PST).

Note: it takes up to 8 hours for the Offline Address Book to be distributed to Client Access Servers to which Outlook is connecting, so it may take up to 32 hours for the freshly generated Offline Address Book to be updated in Outlook client.

You should repeat synchronization again after 5 AM PST on Exchange Hosting to retrieve the updated address book from the server.
