Creating and assigning public folder permissions

New-PublicFolder -Name "UK"  -MailEnabled $true Path "\"

Remove-PublicFolder -Identity "\UK"

By default all users have "Author" rights on the public folder - so we will remove this in our case - but firstly we should remove it's exisiting permisisons:

Remove-PublicFolderClientPermission -Identity "\Test" -User "Default"

and then assign "Default" (all users not defined within the permissions) no access rights:

Add-PublicFolderClientPermission -Identity "\Test" -User "Default" -AccessRights "None"

We can then explicity assign permissions to induvidual users:

Add-PublicFolderClientPermission -Identity "\Test" -AccessRights PublishingEditor -User <username>

or to a root public folder and all of it's child public folders using a powershell script included with Exchange:

AddUsersToPFRecursive.ps1 -TopPublicFolder "\Test" -User "Username" -Permission Reviewer

To delete a public folder and all of it's child folders (recursive delete):
Remove-PublicFolder -Identity "\Test\Directory Folder" -Recurse

We can review public folder permissions with:

Get-PublicFolderClientPermission "\Test"
