Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi, A Kim MacOS
Welcome to the Microsoft Community.
I understand that you are unable to activate Microsoft 365 on your Mac. And, I would love for you to be able to use it properly.
I read your description carefully, which means that when you log in to this site, under “Services & Subscriptions”, the subscription and device information you see is fine, right: Microsoft account | Sign In or Create Your Account Today – Microsoft
You can try to remove the Office license from the account. To do so, please check this link (just proceed to step 4): How to remove Office license files on a Mac - Microsoft Support
If you are still unable to activate your Microsoft 365 on your Mac after doing the above, you can contact the Live Chat support team to help you activate Microsoft 365 remotely by following the steps below:
- Visit this website: https://support.microsoft.com/en-us/home/contact
- Type in your problems in the search box there. For instance, activation, etc.
- Now click Get help, and Select Contact Support below.
- Go to the Products and services tab, and choose either Microsoft 365 and Office category or Other Products
- On the Category tab, choose Manage My Subscription or other alternatives.
- Go to Confirm.
- You can now choose the option of Chat with a support agent on your web browser.
Please Note: The Chat support team only works at certain times, so if the last window says you are not available, try to open it again the next day. If you prefer phone support, you can leave a phone number. That way, they can call you and help you.
Thank you for your understanding and patience. I hope your problem is solved successfully.
Best Regards,
