Just can't get enough of IT

This blog is about mostly anything in IT. But the primary focuses are Microsoft technologies like Exchange Server, Microsoft 365, Microsoft Teams, and Cloud Security.

When you maintain a number of servers which require to trigger the same scheduled task manually, you can simplify the process by triggering the scheduled task remotely.

In this example, I assume that the script is being executed on a dedicated management server (aka job server) within an Exchange Server 2013 environment. The scheduled task must exist on all servers having the same name.

Create a simple PowerShell script at a file location of your choice (i.e. D:\Scripts\Start-RemoteScheduledTasks.ps1)

$cimSession = New-CimSession -ComputerName SERVER1,SERVER2,SERVER3,SERVER4
Start-ScheduledTask TASKNAME -CimSession $cimSession
Remove-CimSession $cimSession

Now create a new shortcut on your server desktop with the following configuration:

Target: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -command "& D:\Scripts\Start-RemoteScheduledTasks.ps1"

If required, select "Run as Administrator" in Shortcut -> Advanced settings.

This script removes the proxy address(es) for a selected protocol from mail-enabled public folders.

Any proxy address with a given protocol is removed from the proxy addresses list.

The script can fix the alias of mail-enabled public folders as well. The code used is based upon a blog post by Shay Levy.



# Check mail enabled public folders for proxy addresses having "MS:" as a protocol type.
# Do not remove and update addresses, but log found addresses to RemovedAddresses.txt

.\Clean-MailEnabledPublicFolders.ps1 -ProtocolToRemove "MS:*" 

# Check mail enabled public folders for proxy addresses having "MS:" as a protocol type.
# Remove and update addresses and log found addresses to RemovedAddresses.txt

.\Clean-MailEnabledPublicFolders.ps1 -ProtocolToRemove "MS:*" -UpdateAddresses


Version History

Exchange Server 2013 Exchange Server 2016 Description

This script deletes all Exchange 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 the environment variable and used to build an administrative UNC path for file deletions.

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

  • It is assumed that the Exchange setup path is IDENTICAL across all Exchange servers, when not using the UseDynamicExchangePaths parameter
  • The IIS log file location is read from the local IIS Metabase of the LOCAL server where the script is executed and is used to build an administrative UNC path for IIS log file deletions
  • It is assumed that the IIS log file location is identical across all Exchange servers
  • Use IsEdge switch when running on an Exchange Server holding the EDGE role


# Delete Exchange and IIS log files older than 14 days 

.\Purge-LogFiles -DaysToKeep 14

# Delete Exchange and IIS log files older than 7 days with automatic discovery

.\Purge-LogFiles -DaysToKeep 7 -Auto

# Delete Exchange and IIS log files older than 7 days with automatic discovery and send email report

.\Purge-LogFiles -DaysToKeep 7 -Auto -SendMail -MailFrom -MailTo -MailServer

# Delete Exchange and IIS log files older than 14 days, but copy files to a central repository and compress the log files before final deletion

.\Purge-LogFiles -DaysToKeep 14 -RepositoryRootPath \\OTHERSERVER\OtherShare\LOGS -ArchiveMode CopyZipAndDelete

# Delete Exchange Server, IIS, and HTTPERR log files older than 7 days, and send an HTML email. Identify Exchange file paths using AD configuration objects.

.\Purge-LogFiles.ps1 -DaysToKeep 7 -SendMail -MailFrom -MailTo -MailServer -UseDynamicExchangePaths -IncludeHttpErr

Exchange Server 2013 LogoUninstalling Exchange Server 2013 will fail if the PowerShell MachinePolicy or UserPolicy is set by GPO.

You will receive an error message referencing Microsoft KB article 981474, which refers primarily to Exchange Server 2010.

Screenshot showing the PowerShell Execution Policy Error


The following PowerShell command removes the GPO setting.

Set-ItemProperty -Path HKLM:\SOFTWARE\Policies\Microsoft\Windows\PowerShell -Name ExecutionPolicy –Value ""

After setting the ExecutionPolicy attribute to an empty string, Exchange Server 2013 can be uninstalled successfully.




Do you plan to deploy Exchange Server 2016 or do you plan to go hybrid with Office 365?

The script sends a given number of test emails to a configured SMTP host for test purposes (primarily Exchange queues, transport agents, or anti-virus engines).

Do not forget to adjust script variables to suit your local Exchange infrastructure.



# Send 10 normal emails
.\Send-TestMail.ps1 -Normal -MessageCount 10

# Send an Eicar test email
.\Send-TestMail.ps1 -Eicar
