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' Since then, I have changed organisations and my old account has expired.
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).
