Exchange Server 2010 – Issues Uninstalling Exchange

Yesterday, I was in the process of uninstalling the UM Role from an Exchange Server 2010 Server which we had set to decommission now that we are migrating to Exchange Server 2016.

Running Setup /mode:Uninstall from the following directory C:\Program Files\Microsoft\Exchange Server\V14\Bin – I ran into my first error.


The tmlisten service is our Officescan Antivirus which was running at the time. I promptly unloaded the service and tried the uninstallation process again which generated the following error:


C:\Program Files\Microsoft\Exchange Server\V14\Bin\ManageScheduleTask.ps1 is not recognized as the name of a cmdlet, function, script file, or operable program.

I found a possible solution here:

Moved the ManageScheduletask.ps1 and ManageScheduletask.strings into the Bin directory from the Scripts directory. Apparently it may be a bug, re-ran the uninstalltion process but unfortunately the process failed again.

This time I was in a far worse situation since I had a half uninstalled version of Exchange on my UM server. The application was no longer visible in Programs and Features but the directory was clearly there (albeit missing files) and running Get-ExchangeServer clearly displayed the Exchange server in question.

I didn’t want to manually remove the server entries with ADSIEdit so I reinstalled Exchange Server 2010 SP3 only (we were at CU level 18 ).¬† Then reran the uninstallation process again.

The process failed yet again this time Setup could not find the following file ConfigureNetworkProtocolParameter.ps1 under the Scripts directory. Checked this location and indeed the file was missing because I cross referenced it with another Exchange server. I copied this file into the directory reran the process and was finally able to perform a clean uninstallation of Exchange.


Exchange Server 2010 – Removing a Public Folder Replica

Microsoft has provided scripts to help with Public Folder management, in the event you need to remove a Public Folder Database from replication to the scripts directory of your installation path for Exchange.

Example: C:\Program File\Microsoft\Exchange Server\V14\scripts

Run the following:

.\RemoveReplicaFromPFRecursive.ps1 -TopPublicFolder “\” -ServerToRemove “NameofYourMailboxServer”

This will take some time to replicate. Once complete run the follow command to verify that all Public Folder replicas have been removed from this Public Folder Database.

Get-PublicFolder -Recurse | ft Name,ParentPath,Replicas

The replica for the given Public Folder Database should be removed. You can then proceed with removing the Public Folder Database.

Remove-PublicFolderDatabase “Name of your “PublicFolderDatabase”

Exchange Server 2016 – Remote Connection via Powershell (Windows 10)

On your remote machine open Powershell – Populate a variable with the credentials you will use to connect to your Exchange server2018-07-16_12-02-552018-07-16_12-05-07

Next type the following command to create a new session with the given credentials

$session = New-Pssession -ConfigurationName Microsoft.Exchange -connnectionuri http://yourservernameFQDN/powershell -authentication Kerberos -credential $credentials

Once this command is complete import the Exchange Powershell module to your machine using the following command.

Import-Pssession $session


Exchange Server 2010 – Unable to Remove Public Folder Database

When attempting to remove a Public Folder Database in Exchange 2010 you receive the following error message below: MapiExceptionMdbOffline: Unable to determine if the store has local replicas (hr=0x80004005, ec=1142).


In my case this Public Folder Database was only a replica on a mailbox server which we had set to decommission. I was unable to mount or remove this PF Database via Powershell or EMC.

One method is to remove the Public Folder Database with ADSIEdit. First, take a backup of your Active Directory environment. Then open ADSIEdit from your primary DC and go to the following location. Configuration: CN=Configuration, DC=domain, DC=com; CN=Services; CN=Microsoft Exchange; CN= Domain name; CN=Administrative Groups; CN=Exchange Administrative Group; CN=Databases; CN=PublicFolderDatabaseName

After removing the Public Folder Database restart the Information Store, the Public Folder Database will be removed.
