Offline address book exchange 2016 not updating

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.

We were having issues with their Exchange 2013 servers and one node would crash or lose connection and break the DAG replication.

What ended up happening is about a day later if a user tried to manually download the address book, they would not be able to and would get a 0x80190194 error: Troublshooting So what is this? Well, let’s look at the log files for OAB downloading.

In Exchange Server 2013, these files are located in the %Exchange Install%\Logging\OABDownload directory.

Open up the latest log file in the directory and see what errors are being reported by the client.

In our case, we had these error messages: Notice the error “Is Local OABFile Current: Manifest Enforcement Disabled And Local File Too Old”.

The file location is correct and shows where the current OAB files are.
