I have an Exchange 2010 install. The server has two disks: C: drive for OS and Exchange program structure and an E: drive that contains the datastore and it's associated Log files.
The C: drive free space keeps shrinking and I can't find what's filling it up. It's a slow shrink, so whatever is getting added to it each day isn't large. I've checked the obvious folders like c:\Windows\system32\logfiles and that's under control. I've also looked at the log files associated with the various processes under the Exchange folders on the C: drive under Program Files and while some of them are large, Exchange is keeping that cleaned up to a max of 30 days. I've also looked and cleaned log files under c:\inetpub. I'm getting frustrated that I can't locate this leak. Thoughts?
