IMPORTANT NOTE

Update to most current release if you are using v2.1

Purge-LogFiles.ps1

PowerShell script for modern Exchange Server environments to clean up Exchange Server and IIS log files.

Description

This script deletes all Exchange Server and IIS logs older than X days from all Exchange 2013+ servers that are fetched using the Get-ExchangeServer cmdlet.

The Exchange log file location is read from a variable and used to build an administrative UNC path for file deletions. It is assumed that the Exchange setup path is IDENTICAL across all Exchange servers.

Optionally, you can use the Active Directory configuration partition to determine the Exchange install path dynamically, if supported in your Active Directory environment.

The IIS log file location is read from the local IIS metabase of the LOCAL server and is used to build an administrative UNC path for IIS log file deletions.

Currently, it is assumed that the IIS log file location is identical across all Exchange servers.

Requirements

• Windows Server 2012 R2 or newer
• Utilizes the global function library found here: http://scripts.granikos.eu

UseDynamicExchangePaths

• None = All log files will be purged without being copied
• CopyOnly = Simply copy log files to the RepositoryRootPath
• CopyAndZip = Copy logfiles and send copied files to compressed archive
