I've been working on a new project and found that the same user account is the administrator on 3 organisations on a Dynamics 365 tenancy. I'd like to change the Administrator account on each of the environments to reflect their use (Dev, Test and Prod). In Dynamics 2013/2011 I was able to change the username in the user form and that would be enough. How can I achieve the same in Dynamics 365 (2016 Update 1)?
