I'm running Outlook 2007 on a Win7 Pro machine and I'm getting strange, almost duplicate, emails from known contacts. One of the messages will be normal and one will say unable to read. When I click on one of the kind-of-duplicate emails both emails are selected. When i try to delete the one that is unable to be read it doesn't work but when i delete the normal one, only that one gets deleted, but the other can than be deleted. It's happened a few times now from both contacts outside my organization as well as internal contacts. There are no rules setup or anything either, so I'm stumped.
