How do I sign in to both of them simultaneously in the same web browser? Is there a way to do so based on the domain that is being accessed?
I have a work Microsoft account used for Azure, Visual Studio, Office 365, and etc. that is firstname.lastname@example.org. I also have a personal Microsoft account that I use for Xbox Live, Bing, my personal PC, and etc. that is my Windows Live ID.
This worked up until about a week ago when suddenly, accessing one of the Microsoft services began redirecting me to a single signon page saying that I was already logged in with my personal account and that I would have to sign out to use my work account.
