Additionally, when this issue occurs, you may encounter one or more of following problems:
- The scheduled OAB generation doesn't occur.
- If OAB generation is forced by calling the Update-OfflineAddressBook cmdlet, the command is completed successfully. However, the OAB distribution folder isn't updated.
- There are no warning or error events in the Application log about the OAB generation failure.
- The OAB generation logs aren't updated at all. (You can find these logs in the \Logging\OABGeneratorLog folder.)
