I've got an exchange 2003 standard instance running on a server 2003 box. this is an inherited problem from before my time but it seems the exchange server is extremely low on disk space. after digging around I've found that the mail.log folder which it's my understanding contains the change logs for the mail store database (please correct me if i'm wrong on this) has log files that reach back to 2005. I thought that backup exec was supposed to remove these files after every full backup. Is it safe to delete some of these?
