Thank you for the help but that is not the solution. Forwarding is turned off in outlook.com. I found out a new detail...
1. When I receive an email to my gmail address, gmail forwards it to my outlook.com, I only have one copy of the email.
2. When I receive an email to my office.com address, I receive the email twice.
Logic tells me that emails to my outlook.com address go to both outlook.com and hotmail.com and hotmail.com still has forwarding turned on even though there is no email forwarding on outlook.com.
I had a feeling something like this would happen because when I was switched to outlook.com my email forwarding did not carry over, I had to turn it on.
