Removing a Microsoft Exchange account from Outlook 2013?

Question

Microsoft

I don’t understand what outlook wants from me :)
Is it a crooked translation, or what is it?
Multiple entries connected. Gmail mail, random hosting mail and 2 microsoft exchange accounts. One of which is basic and the other is not. Here is what I am trying to remove.

Answer 1

Create a new data file and make it "default"

Answer 2

Try using a different default data file (maybe it's better to try creating a new one)
Try setting non-exchange mail as the default.
