Removing old log files

Here is a simple script to remove old log files from Exchange Servers at the %ExchangeInstallPath%logging folder. Here, I have used the default installation path of Exchange, but it can be modified to use a variable with a non-default path of the Exchange installation. The number of days can be modified to suit your needs:

$Days = 30 

$ExchangeLogsPath="C:\Program Files\Microsoft\Exchange Server\V15\Logging\"
	
Write-Host "Removing IIS and Exchange logs from Default Directories except last $Days days"

$Now = Get-Date

$LastModified = $Now.AddDays(-$Days)

$LogFiles = Get-ChildItem $ExchangeLogsPath -Include *.log -Recurse | Where {$_.LastWriteTime -le "$LastModified"}

foreach ($File in $LogFiles)

{Write-Host "Deleting file $File" -ForegroundColor Red; Remove-Item $File -ErrorAction SilentlyContinue | out-null}
