Use Windows PowerShell to count and list total number of items in Folders E-Mail in Office Outlook?

Question

I have the need to generate a list of all outlook folders and the total number of items listed beside each folder name. I thought I could simply modify the script from " http://blogs.technet.com/b/heyscriptingguy/archive/2009/01/26/how-do-i-use-windows-powershell-to-work-with-junk-e-mail-in-office-outlook.aspx
" regarding the total number of items in the junk folder but no luck.
I thought I could just simply duplicate line 6 of the aforementioned script
"$folder = $namespace.getDefaultFolder($olFolders::olFolderJunk) " and change the folder name but getting the "Method invocation failed because [Microsoft.Office.Interop.Outlook.OlDefaultFolders] does not contain a method
named 'olFolder'.
At line:7 char:1
+ $folder = $namespace.getCurrentFolder($olFolders::olFolder("Design Engineering S ...
I've found a way to export a list of all these folders using exportoutlookfolders.vbs to a txt file but doesn't include total number of items.
Looking for any pointers on how to make this work. Don't expect anyone to write it for me but I am still learning PS. Would be great to find a way to import all of these folder and subfolder names into the script. Will be appreciative of any advice though.
There's an enormous amount of Outlook folders.
Outlook 2013
Windows 8
Thanks,

Since I am not and administrator, but an end user, I do not have access to the Get-Mailxxxx commandlets to make this really easy and had to do this long hand.
  The following will pull folder.name, folder.items.count, and sum the total size of each folder's items for all folders and their subs. 
Just one warning, the summation can take some time with a large PST file since it needs to read every email in the PST. 
There is also some minor formatting added to make the results a little more readable.
$o
= new-object
-comobject outlook.application 
$n
= $o.GetNamespace("MAPI") 
$f
= $n.GetDefaultFolder(6).Parent 
$i
= 0
$folder
= $f
# Create a function that can be used and then re used to find your folders
Function
Get-Folders()
{Param($folder)
 foreach($folder
in $folder.Folders)   
{$Size =
0
$Itemcount
= 0
$foldername
= $folder.name
#Pull the number of items in the folder
$folderItemCount
= $folder.items.count
#Sum the item (email) sizes up to give the total size of the folder
foreach ($item
in $folder.Items)
{$Itemcount
= $Itemcount
+ 1
$Size =
$Size +
$item.size
Write-Progress -Activity ("Toting size of "
+ $foldername
+ " folder.")
-Status ("Totaling size of "
+ $Itemcount
+ " of "
+ $folderItemCount
+ " emails.")
-PercentComplete ($itemcount/$folderItemCount*100)
# just a little formating of the folder name for ease of display
While($foldername.length
-le 19){$foldername
= $foldername
+ " "}
#Write the results to the window
Write-Host ("-folder "
+ $foldername
+ "  
-itemcount " +
"{0,7:N0}" -f
$folderItemCount +
"   -size " +
"{0,8:N0}" -f ($size/1024)
+ " KB")
#If the folder has a sub folder then loop threw the Get-Folders function.
#This two lines of code is what allows you to find all sub folders, and
#sub sub folders, and sub sub sub for as many times as is needed.
If($folder.folders.count
-gt 0)
{Get-Folders($folder)}
get-folders($folder)
