Double outlook email icons?

[lcw731]

When I got my phone I set it up with and exsisting outlook.com email address. For some reason not all the featytures were activated. Today I activated office 365 with the same emaill address, now I have two outlook email boxes and I can't delete the new one, just pin it or unpin it. thenewbox is the same address as the old, so Im just gettign everything twice in places. If I like the boxes is get everything twice in the same place. Any thoughts?
