After migrating to a new computer when trying to active Office 2016 I'm getting the following error message:
Another account from the same organization is already signed in. To switch accounts, please go to Applications/Utilities/Keychain access, clear all entries including the 'Office' keyword, and then restart the app.
I tried following the steps here https://medium.com/@wangyidan621/microsoft-office-activation-and-keychain-removal-19664b1e7e77 but it didn't solve the issue.
