Have an Exchange 2000 server and we are currently running out of hard drive space. C:\ProgramFiles\EXCHSRVR\MDBDATA is growing exponentially. 5 MB per minute. I assume the logs being generated in this directory are supposed to be flushed and this is no longer happening. We are using an offsite solution for backup called EVAULT. Is there a way I can delete or flush these logs quickly and safely.
