I've seen other questions with this kind of error, but none helped me to solve my problem.
I have my personal apple developer account and one from the company I'm working for. When I'm trying to submit an app for my company in order to beta test it I have an error: "Your account already has a valid iOS Distribution certificate". I tried importing developer profile again, but it didn't helped.
Just for documentation purposes: You need to edit your iOS Provisioning Profile in member center and select the correct Certificate
delete your own apple id is from Xcode "preferences->Account-> Apple IDs. And Start Archive with your company apple ID.
