2016 oab not updating

They do for my colleague sitting next to me, so I don’t think it is a server misconfiguration or something like that.Is there any way I can force a manual update of the Offline Address Book (OAB) in Outlook or reset it completely otherwise?By default, a new OAB is generated every 8 hours in Exchange Server 2016, but you can change the interval by using the Exchange Management Shell.For additional management tasks related to OABs, see Offline address book procedures.Learn how to configure the offline address book (OAB) update interval in Exchange 2016.An offline address book (OAB) is a copy of an address book that's been downloaded so that an Outlook user can access the information it contains while disconnected from the server.

In Exchange Server 2013, these files are located in the %Exchange Install%\Logging\OABDownload directory.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 ;-).Exchange 2013 has gone through an evolution in the way the Offline Address Book is generated and maintained.While most of the changes are advantageous, I ran into a chink in the armor while working with a customer who was having an issue with Exchange 2013 DAG replication.
