I'm in account settings data files and, yes, I do have one too many data files. The third one must be from the old computer.

I moved my saved emails and people folders up to my primary account and made sure all the old Outlook folders were empty.

However, when I select my main account (in account settings), the settings don't allow me to set it as default.

Which brings up another point.

Is my contact list/address book in that 3d file? If so I don't want to delete it. I suppose I could just ignore it.

PS: When I open my mail, it's still defaulting to the inbox of the unwanted folder.
