Can anyone point me to a reference for creating an Outlook Automation object in my Web Service? I haven't been able to find anything that works.

I have the following code in an .asmx page:

        Dim OutlookApp As Outlook.Application = New Outlook.Application()
        Dim OutlookNamespace As Outlook.NameSpace = OutlookApp.GetNamespace("MAPI")
        Dim OutlookContacts As Outlook.MAPIFolder
        Dim OutlookContact As Outlook.ContactItem

Unfortunately, the code comes to a screetching halt on the very first line. I don't get any specific errors, only a HTTP 500. FYI Outlook has been added to the project references and I can see the properties and methods while typing code.
