Configuring preferences and options in Outlook.com
I have had the same issue. I am very annoyed by being automatically directed to MSN. I alone chose what information I look at or not.
So, I am going to need a procedure to stop this from happening. If the best answer is still (2 years later)that this happens by default and I can post a suggestion and hope for a solution in the future then by default I will stop paying my annual fee.
Best regards...
