Outlook address book not updating
This situation however is extremely rare since the default maintenance time on Exchange is at AM and updates and downloads are usually performed during working hours.*** NOTE: The GAL is essentially a real-time / online representation of AD Objects that are Mail Enabled for Microsoft Exchange *** The GAL contains information for all email enabled users, Distribution Groups, and Shared Mailboxes and Exchange Resource Mailboxes.
So to force your Outlook to sync with the Exchange server you can manually update the GAL.The GAL appears to be complete otherwise, but newly-created users do not appear. During the logging I performed a manual update of the Black Berry Manager profile's Address Book.
