Updating the address book

This means that in the worst possible scenario, an update to the Address Book won’t become available to the user until 48 hours after the change.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.

This is called the Offline Address Book and is being generated on the Exchange server.For information about the parameter sets in the Syntax section below, see Syntax.You need to be assigned permissions before you can run this cmdlet.This cmdlet is available only in on-premises Exchange Server 2016.Use the Update-Global Address List cmdlet to update the recipients included in a global address list (GAL).Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you.To see what permissions you need, see the "Address lists" entry in the Email address and address book permissions topic.You can use a date other than the current date to ensure that addresses are in effect for the day that you mail correspondence instead of the day that the addresses were generated.After you enter address book records, you might need to change category code information.Even though Outlook is the last in the chain, it is often the first level where the troubleshooting takes place as usually this is where the request is coming from.And since this website’s main focus is on Outlook, it makes sense to start with Outlook as well ;-).
