We have recently installed MS Exchange 2016 (Build 1591.10) and were in the process of moving all of the log locations to another drive.
We ran into an issue where we could not locate any program, service, or process that corresponds to the following location:
C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Diagnostics\Logs\
This folder is generating a tremendous amount of logs and is eating away at our primary C:\ partition.
The only thing that I have found related to the logs generated in the aforementioned folder is a registry location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Search Foundation for Exchange\Diagnostics
If anyone would happen to know what service, process, or application is generating these logs it would be of great help!
