Do I need to download a new version of Office 365 as a Live.com email user? I keep getting notices saying I will lose access unless I do so,.

Dear fran worrell,

Welcome to the Microsoft Community.

We understand that you need to confirm the installation and mailbox usage information of Office 365.

Since you said that you installed the program in the Mac system but an error message appeared, in order to further help you confirm the problem, we need to know more information from you:

1. How did you install the Office product on Mac? Did you install it from the Apple Store or the Microsoft website?

2. You use a live.com account. Do you have subscription information for Microsoft 365 or other products under your account? If so, what version is your subscription product?

Microsoft 365 product or Office 2021 or other?

3. You said that you were prompted that you needed to upgrade Microsoft 365. Did you display an error when you opened the Office program, or did you display it during other operations?

Has your Office program been activated successfully? You can try to click on any Office program, such as Word, click on the top and select "About Word" to view the status information of your subscription and activation product.

4. You asked whether the version is suitable for home users. Do you have any subscription information for Microsoft 365 on Mac before?

If it is convenient, you can share more information with us to help us confirm the cause of the problem.

Whether using Office programs in Windows or Mac systems, you need to have subscription information under your account and help detect license information to activate the product before you can use it normally.

If you do not activate, your product will not be able to be used, and you will be prompted to upgrade or subscribe to Microsoft 365 products for use.

You can first ensure that there is Office product information under your account:

You can log in to the Microsoft dashboard: Microsoft account | Sign In or Create Your Account Today – Microsoft

Click "Services and Subscriptions" to see if there is product information under the account

You can first confirm the subscription and activation information of the Office product, or you can share the screenshot with us, and we will help you confirm it.

At the same time, if you have not subscribed to Office and need to know the Office license information suitable for you or multiple devices to subscribe, you can learn about it:

Microsoft 365 Personal: Only one account can be logged in, can log in to 5 devices, and has 1TB of OneDrive space.

Microsoft 365 Family: You can log in with 6 accounts including your own account, each account can log in to 5 devices, and each account can enjoy 1TB of OneDrive space.

Buy Microsoft 365 Family & Personal Subscriptions, and Office 2021 - Microsoft Store

You can confirm first, and we also look forward to you sharing more information with us to help you confirm your use.

Best Regards,
