Mass setting replication partners with Public Folders

As you have probally experianced setting replication partners with public folders is a tedious process as you need to do them one by one. However in Exchange 2007 there is a powershell script called AddReplicaToPFRecursive.ps1 under the C:\Program Files\Microsoft\Exchange Server\Scripts that recursively goes through and updates your public folder replication partners for every public folder in a hierarchy that you specify, excellent!

For your default public folders run:

'C:\Program Files\Microsoft\Exchange Server\Scripts\AddReplicaToPFRecursive.ps1' -TopPublicFolder "\" -ServerToAdd Servername

To update your system public folders run:

'C:\Program Files\Microsoft\Exchange Server\Scripts\AddReplicaToPFRecursive.ps1' -TopPublicFolder "\NON_IPM_SUBTREE" -ServerToAdd Servername

Note these commands you will get an error as the very top level folder cannot have replication partners, only the sub folders of a public folder hierarchy! This command is saying start at the parent ahh error, then continue on all the sub folders which will not have a problem! Here is the error that you will recieve - this is normal:

Also one thing to note with this tool, there is a little querk when it comes to spaces when you want to assign ppl at lower levels. Here is an example:

If you simply try to use the following it will fail.
AddReplicatoPFRecursive.ps1 -TopPublicFolder “\PublicFolder with space” -ServerToAdd “servername”

The solution turned out to be to use single quotes inside the double quotes so it should be something like

AddReplicatoPFRecursive.ps1 -TopPublicFolder “’\PublicFolder with space’” -ServerToAdd “servername”

That’s really weird and not standard but it works.

This tool can be used for public folders between exchange 2003 and 2007 as well.


  1. Thanks. This is the ONLY information on the internet regarding adding a replica for the system folders.

  2. Thanks for your post and welcome to check: here

  3. Thanks I searched for about 2 hours to find your blog and the only good information.

  4. Thanks - helpful article.

  5. I have been researching for hours and tried the script on this page; however, I am unable to come up with any reason why I keep getting the following error:

    Set-PublicFolder : Cannot save the object '\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY'. Please make sure that you specified the correct Identity and that you have the necessary permissions to save it.

    It doesn't matter if I try it from exchange management console Public Folder Management tool or through the shell using this script.

    Any Suggestions?
