” Well, the truth of the matter is that our new joiner Joe is in fact , an update to the Address Book won’t become available to the user until about 48 hours after the change.

Because of this, a new user may not be visible in the address book, or changes to a user’s name, address, etc.

may not be available even though such changes have been made in Active Directory.

This can occur even though no errors are present within the OAB rebuild process.

When you have Cached Exchange Mode enabled, Outlook by will by default cache the main Global Address List as well. This is called the Offline Address Book and is being generated on the Exchange server. Due to various synching schedules, it can take up to 48 hours before you could actually see a change in Outlook.
