Configuring preferences and options in Outlook.com
I have the same issue. The "update" occurred sometime this afternoon.
Using FF with msn.com email via Outlook.com
This is one of the dumbest changes that MS has ever done. Yet another example of MS attempting to fix something that wasn't broken. At least give the users the option of changing the settings back to the original position as indicated in previous posts. Having the option buttons on the right side of the screen is cumbersome at best.
The sooner this is fixed the better.
