Global address list not updating exchange 2016 cached mode
Therefore, there is no need for equivalent instructions for the Mac operating system.
If you're having issues with your Outlook address book, such as a new employee's information not showing up, there may be a simple solution.
The Microsoft Exchange default is for this to update at 5 AM each morning.
In addition, if you are using Microsoft Outlook 2010 in cached mode it may be storing an out-of-date copy of the GAL.
Before installing your first Exchange 2013 server during a migration project you must first review your offline address book configuration.
The issue, as explained in detail by Exchange MVP Andrew Higginbotham here, and mentioned by Microsoft in the release notes and a subsequent blog post, is that Exchange Server 2013 will create a new default offline address book for the organization.
If they do not have an Exchange account (they are still mail-enabled), the GAL says their email is "[email protected]" and is told to route that mail back up to the relays, and then it's up to the relays to look up that email redirection field and deliver their mail appropriately.Note for Mac Users: Mac versions of Outlook do not connect to the Exchange server in the same way as PC versions.Every time a Mac checks for new mail, it also updates the GAL.Microsoft Outlook clients use a cached mode of the GAL, called an Offline Address Book that is synced with the GAL at a nearly daily interval.
So, it can take multiple days before a change in on Enterprise level (Banner/NESSIE) will propagate to be visible in Outlook.
In general, OWA offers realtime updates, while Outlook takes 26 hours.
