Clean-Exchange-Log-Files

• PowerShell script taken and adapted from Edward Van Biljon (was on his Technet Gallery, which has been decommissioned in 2020 (original link: gallery.technet.microsoft.com/office/Clear-Exchange-2013-Log-71abba44) with the following modifications:

• No need to modify the IIS and Exchange Path => the script uses environment variables to find the Exchange Logging and IIS Logging paths (script has to be used on Exchange servers to remove the log files)

• added -DoNotDelete switch to just assess the amount of files that we'd potentially remove

• added -NoConfirmation switch to avoir being prompted to continue or cancel

• added progress bars

• added script log file

• added compress before delete

• added version checks - at launch, and during execution it will indicate if a new version is available.

• added an option to log to the working folder

Usage

Will display the folders, compress all files older than 2 days in the IIS folder and Exchange Logging directories, and delete all ZIP files older than than 30 days in the same paths

.\CleanExchangeLogFiles.ps1 -Days 30 -DeleteLodCTRBackup -ZipDays 2

You'll see the progress bars (one for the folder it's cleaning, and one for the files it's cleaning for each folder):

Usage on a Windows Scheduled task

NOTE: to use in a Windows Scheduled task, use the -NoConfirmation switch to bypass the Confirm Yes/No dialog box. Otherwise the script will just wait for a user input, which will never come because it's a Windows Scheduled task, most likely configured as "non interactive" because we want it to be automatic.

In that case, use the -NoConfirmation switch:

.\CleanExchangeLogFiles -Days 30 -ZipDays 2 -NoConfirmation

This will launch the script in files deletion mode immediately, without the need of a user interaction.

Log file

The script log file will be located on the user's Documents folder, or if LogHere is specified, the start in folder.
