The Size of Priv1 .EDB and HTML on my Exchange 2000 both are making like 15 GB although I don't have a big list of email accounts, its max 50. It 16 GB a week back I run offline defragmentation and used NT Backup. It reduces just 3GBs and today its again on 15GB. Definately if in a week it gained 2GB then in 2 or 3 days my Exchange will be down. Kindly help me how to reduce the size of these files.
