Cleanup logs Exchange 2013/2016/2019

Starting from Exchange 2013 and higher, logs are taking up more space on the Windows Server. This is when cleanup logs Exchange 2013/2016/2019 script plays an important role. Clear Exchange logs with PowerShell and get free space on the Exchange Server. These logs are NOT database logs! You can safely delete these logs. In fact, I recommend you to delete them.

Logs are great when you need more information and want to have a look into it when you are having issues. Exchange Servers are filling up easily with all these logs. The best way is to clear the logs because you need to free up some size on the disk. The script in this article is my edit to the original script from MVP Edward van Biljon. You can download the official script from Microsoft Technet.

Prepare the cleanup logs Exchange script

Make sure that you change line 2. At the moment it is showing $days=2. That means it will cleanup logs from the Exchange Servers that are older than 2 days.

If you have changed the path of the Exchange configuration, change the path in the line 3, 4, 5 and 6.

Save the file on the Exchange Server in the following path C:\scripts\. Give it the name CleanupLogs.ps1

Give your account permission access to the below four folders. If the script does not have permission, it will not cleanup logs in that folder. I recommend making a service account in Active Directory. Give the service user account read/write permission on the below four folders. Create a scheduled task to clear Exchange logs that will run every day with the service user account.

  1. Never did check those logs, then suddenly the mail queue is hanging. This script was a real life saver, thank you very much!

  2. Great script which regained me around 20GB of space on my server that was slowly but surely running low on space. I now have time to address my disk space issue at a more leisurely pace. Thanks.
