2016 oab not updating
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.

Dear All, I have an issue which is annoying a lot, OAB is not updating GAL on Outlook 2007 in Cache Mode. Exchange 2010 Outlook 2007 - Cache Mode OAB is distributed via Web based and Public folders.
I disable cache mode and it works fine but I don't want to keep it disabled, I also tried by delete the OAB file in C:\Users\username\App Data\Local\Microsoft\Outlook\Offline Address Books and download OAB manually rather then waiting for 24 hours, it's still same.
When you have Cached Exchange Mode enabled, Outlook by will by default cache the main Global Address List as well.
This is called the Offline Address Book and is being generated on the Exchange server.
In that case the whole OAB is being downloaded again.
I also waited for 24 hours to download automatically but no difference.
I also tried other different options such as, recreating new GAL, reboot server, restart Exchange File Distribution service, checked IIS that OAB is available there, but nothing worked.
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.
