OK, I know that is not a helpful answer...
Just what is it you are getting? Two identical emails? Two different emails? Two identical attachments in one email? Two different attachments in one email?
I think I am not grasping the problem. Why not just read one of them, and ignore the other?
If it is two messages, you could probably set-up a filter to toss the duplicate. With a bit more work, same for attachments. But I'm not an Outlook user, so not sure how much filtering you can do or how easy it is.
