Outlook offline address book not updating exchange 2016
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.
When trying to perform a manual download (Send and Receive - Download Address Book), it wasn’t in the list.
Also when using the “Test EMail Auto Configuration..” (by holding CTRL and right click on Outlook System Tray icon) to examine the Auto Discover information, there was no OAB URL (OABUrl in XML) being sent to the clients.
Therefore, different people will receive updates at different, random times.
