What to do when POP3 is not allowed in Microsoft Outlook?

I’m helping a customer migrate e-mails from a Notes mail databases to Microsoft Outlook MSG-file format today. For this process we needed to extract all the e-mails using Outlook POP3 access to Domino. Nice and easy. Unfortunately the installed Outlook client didn’t allow us to configure a POP3 account in Outlook. What to do? Look to Google to provide the answer.
