Powershell and Outlook Issues

So my ultimate goal is to export emails after a specific length of time as a .msg and then upload them to sharepoint for archival purposes.

My issue is all the examples I find never seem to work for me. I use PowerGUI for my ISE, I have powershell 2.0 and Outlook 2007 SP3

So for example, when I try something very simple according to the scripting guy Reference, I try this line of code:

[Reflection.Assembly]::LoadWithPartialname("Microsoft.Office.Interop.Outlook") | out-null

[enum]::GetNames("Microsoft.Office.Interop.Outlook.OlDefaultFolders")

This should list the enums used to point to the different folders in outlook....here are some of them:

olFolderDeletedItems
olFolderOutbox
olFolderSentMail
olFolderInbox
olFolderCalendar
olFolderContacts
olFolderJournal

When I run it, either PowerGUI or straight in the console I receive the following error:

Cannot convert argument "0", with value: "Microsoft.Office.Interop.Outlook.OlDefaultFolders", for "GetNames" to type "System.Type": "Cannot convert the "Microsoft.
Office.Interop.Outlook.OlDefaultFolders" value of type "System.String" to type "System.Type"."
At C:\Users\clayman\AppData\Local\Temp\ceb3eca9-5cf1-4dd2-92aa-c2c29d3ca438.ps1:2 char:17+ [Enum]::GetNames <<<< ("Microsoft.Office.Interop.Outlook.OlDefaultFolders")+ CategoryInfo          : NotSpecified: (:) [], MethodException+ FullyQualifiedErrorId : MethodArgumentConversionInvalidCastArgument

Truth be told, no matter what sample I try they all fail, for instance try and run this function (yet another scripting guy article)

Function Get-OutlookInBox
{
  Add-type -assembly "Microsoft.Office.Interop.Outlook" | out-null
 $olFolders = "Microsoft.Office.Interop.Outlook.olDefaultFolders" -as [type] 

 $outlook = new-object -comobject outlook.application
 
 $namespace = $outlook.GetNameSpace("MAPI")
 $folder = $namespace.getDefaultFolder($olFolders::olFolderInBox)
 $folder.items | 

 Select-Object -Property Subject, ReceivedTime, Importance, SenderName
}

And this one fails with:

Add-Type : Could not load file or assembly 'Microsoft.Office.Interop.Outlook, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dep
endencies. The system cannot find the file specified.

If I change:

Add-Type -AssemblyName "Microsoft.Office.Interop.Outlook" | Out-Null

To:

[Reflection.Assembly]::LoadWithPartialName("Microsoft.Office.Interop.Outlook") | Out-Null
