Commented Issue: Can't open emails in Outlook 2013 [8411]

After installing Outlook 2013, when I double-click the email in smtp4dev it opens a dialog in Outlook 2013 that says, "The attempted operation failed. An object could not be found."

Not sure if this is a smtp4dev problem or an Outlook 2013 problem.

I get, "Cannot start Microsoft Outlook" when Outlook is closed. When Outlook is started, I get the same error as above.
