It is BAD BAD practice to try and delete the exchange 2007 log files! It should not be done ever!

Running into space issues on exchange needed to remove 80,000+ *.log files. These would be removed by doing a backup, but without any space to run the backup there’s not a lot of options.

I ran this command to perform a removal of the log files in the mailbox DB, I had to use this script the job as the windows would crash as soon as multiple files were highlighted and selected for deletion:

• CD /D E:\Exchange\Mailbox\First Storage Group
• del /s *.txt

In order to move logs onto another drive use this command:

• CD /D E:\Exchange\Mailbox\First Storage Group
• move *.log “K:\Exchange_Logs_Move”

DO NOT DELETE / REMOVE THFOLLOWING FILES:

• E00.chk
• E00.log
• Mailbox Database.edb
