How can I change the name of my out going email. My name changed after the Microsoft server change and my name on my emails has changed to a name that is not valid. It is correct when accessing Outlook.com via IE but when using outlook 2016 the name has changed. I deleted the outlook 2016 and re entered but my name was changed from firstname.lastname@example.org to alias@outlook_6A1C9BDE66559223@outlook.com. I need to change the name back to the real one.
