Starting with Exchange 2013 there are now three groups of transport related logs: Front-End (new to 2013), Back-End (or just Transport), and Mailbox Transport. By default, these logs all go under the directory where you install Exchange, which is the C: (system drive) by default. I’ve seen these logs easily take up GBs of space since they are saved for 30 days, by default, and generate many lines in multiple logs for each message transmitted.

So I created this script to easily reconfiguration the location of these logs to save space on the install drive and make troubleshooting\finding these logs easier. I also enable NTFS compression on my D:\Logs directory to further save space. In my environment I have two Exchange 2013 servers, three Exchange 2016 servers, and two EDGE 2016 servers. This script will exclude any server with the name “EDGE” in it, since normally the EDGE servers are in the DMZ and can’t be accessed from the internal network and some transport cmdlets can’t be run against an EDGE server directly.

This script will not move the old or currently opened log files, so you will need to some some manually clean-up.
