Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear AilishB,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
We are sorry to hear that you’re having trouble with activating Microsoft 365 apps on a Mac. I deeply understand the inconvenience caused and apologize for it.
From the issue description, it seems like you have performed all the troubleshooting steps, and it appears that the issue might be caused by your local environment. Given this situation, I would suggest you follow the methods below and see if they could help in your scenario:
- Could you please boot your Mac in safe mode and try to activate the Microsoft app? Refer to: Start up your Mac in safe mode - Apple Support.
- The local settings might have affected the application. Therefore, we would like you to check whether the issue is related to your user profile. In this situation, we suggest you create a new user account on your Mac: New user or group setup on Mac - Apple Support. See if it still alerts you with the same error message. It is worth trying because it will help you narrow down whether the issue is caused by a specific corrupted user profile.

We appreciate your understanding that sometimes the initial response may not resolve the problem immediately. However, we can work together to narrow down and resolve the situation. So, for further troubleshooting, could you please provide the information below:
- Could you please provide me the specific mac OS version you are using?
- Could you please provide me the specific Microsoft apps version you are using?
- Could you please check If you have the latest desktop version of Office license, by going to the Office 365 subscriptions page while signed in with your A3 student account.
Once again, I apologize for the inconvenience this has caused. We appreciate your patience and understanding and thank you for your time and cooperation.
Sincerely,
