With the latest Insider Fast build, Office users on Windows can now seamlessly switch between different accounts. This build comes with the new account manager that will display all of your work and personal accounts in one place. You can now clear see the current logged in account, and you can even switch between work and personal accounts without having to sign out.
This feature is now available on Word, Excel, PowerPoint, OneNote, Access, Project, Publisher and Visio. To access the new account manager, click your name in the top right corner of the app.
