How to clear Exchange Logs without any impact for Exchange 2016 (CU19) C Drive Disk space increase fastly.

Question

Hello Support

I got the script for clearing logs. These are fine

is it safe to delete below the path of logs? after the backup completed?

Set execution policy if not set

$ExecutionPolicy = Get-ExecutionPolicy
if ($ExecutionPolicy -ne "RemoteSigned") {
Set-ExecutionPolicy RemoteSigned -Force
}

Cleanup logs older than the set of days in numbers

$days = 2

Path of the logs that you like to cleanup

$IISLogPath = "C:\inetpub\logs\LogFiles\"
$ExchangeLoggingPath = "C:\Program Files\Microsoft\Exchange Server\V15\Logging\"
$ETLLoggingPath = "C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Diagnostics\ETLTraces\"
$ETLLoggingPath2 = "C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Diagnostics\Logs\"
$ExchangeLoggingPath = "C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\Logs\"

Clean the logs

Function CleanLogfiles($TargetFolder) {
Write-Host -Debug -ForegroundColor Yellow -BackgroundColor Cyan $TargetFolder

if (Test-Path $TargetFolder) {
    $Now = Get-Date
    $LastWrite = $Now.AddDays(-$days)
    $Files = Get-ChildItem $TargetFolder -Recurse | Where-Object { $_.Name -like "*.log" -or $_.Name -like "*.blg" -or $_.Name -like "*.etl" } | Where-Object { $_.lastWriteTime -le "$lastwrite" } | Select-Object FullName
    foreach ($File in $Files) {
        $FullFileName = $File.FullName  
        Write-Host "Deleting file $FullFileName" -ForegroundColor "yellow"; 
        Remove-Item $FullFileName -ErrorAction SilentlyContinue | out-null
    }
}
Else {
    Write-Host "The folder $TargetFolder doesn't exist! Check the folder path!" -ForegroundColor "red"
}

}
CleanLogfiles($IISLogPath)
CleanLogfiles($ExchangeLoggingPath)
CleanLogfiles($ETLLoggingPath)
CleanLogfiles($ETLLoggingPath2)

Our forum does not support scripting on demand so far. If you need a script to complete a job, you may need to open a ticket to Microsoft which supported for it.

About this existing script, you can modify those two places, then this script will generate and save a log:

If you want to send it with email, you will need to writing another script to do it.

Thank you KyleXu

is it safe to cleanup below paths of logs?

$IISLogPath = "C:\inetpub\logs\LogFiles\"
$ExchangeLoggingPath = "C:\Program Files\Microsoft\Exchange Server\V15\Logging\"
$ETLLoggingPath = "C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Diagnostics\ETLTraces\"
$ETLLoggingPath2 = "C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Diagnostics\Logs\"
$ExchangeLoggingPath = "C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\Logs\"

Answer 3

yes, absolutely.
The only logs you do not want to clear using a script are the Exchange database transaction logs.

If anyone else want to have a read about the script. The original article with the script can be found in the below post:
