Note 2: I have already tried removing the Office applications completely and reinstalling, as described in the Support Article (). Note 1: Outlook is already set up and using my current account as it's primary address. Or, how can I change the account these applications are activated from? How can I deactivate the Office for Mac applications? When I enter my credentials, I am simply told that no Microsoft Account exists for this address. I am prompted to log in with a personal 'Microsoft Account' and the screen shows no way to log in with my 'Work or School' account. Now when I open any Microsoft Office 2016 for Mac applications, I am presented with the 'Account Notice' dialogue box, which states, 'We've run into a problem with your Office 365 subscription, and we need your help to fix it.' When I click 'Manage My Settings' The company also publishes books (through Microsoft Press) and video games (through Xbox Game Studios), and produces its own line of hardware. It is best known for its Windows operating system, the Microsoft Office family of productivity software plus services, and the Visual Studio IDE. Since then, I have changed organisations and my old account has expired. Microsoft is a prolific developer of personal computer software. This software was provided by my company (Enterprise E3 subscription). When I started Word for Mac I was prompted to log in, which I did successfully, and my software was activated.

I installed the Office 2016 desktop applications on my Mac (OS X 10.11.16).
