How to create Exchange Public Folders for Appointments
Created: 04.10.2011
Categories: Exchange Development; Exchange; PowerShell

      Unfortunately the PowerShell cmdlet New-PublicFolder doesn’t allow different types for public folders. But with a small trick you can set the type later. The code requires CDOEX that runs locally only.

      PowerShell Code:
      $FolderPath = "/TEMP"
      $NewFolder = "CalendarTest"
      $PFRoot = "file://./backofficestorage/ Folders"

      # Use PowerShell cmdlet to create new folder
      # (depending upon whether a root folder or not)
      if ($FolderPath -ne "")
        $f = $FolderPath -replace("/", "\")
        New-PublicFolder -Name $NewFolder -Path $f
        New-PublicFolder -Name $NewFolder

      # Use ADO to change the folder type
      $o=New-Object -comobject ADODB.Record
      while (($updated -eq $false) -and ($timeout -gt 0))
        $o.Open($PFRoot + $FolderPath + "/" +
         $NewFolder, "", 3, -1, -1, "", "")
        foreach($item in $o.Fields)
        if($item.Name -eq


      if ($updated -eq $false)
      Start-Sleep -s 1
      $timeout --
