Question

Microsoft Office stopped letting me edit. Requires Office 365 to edit

Michael Jacobs 40

I purchased Office Home & Business 2021 for Mac in 2023. I have been using this with no issue.

Today, Word and Excel stopped allowing me to edit, and have a yellow bar at the top that state "Activate Microsoft 365 to Create and Edit".

I have no made no changes to my Mac nor anything Microsoft. I created a document 2 days ago and saved it. Today, I opened the document to edit, and I received that message.

Please advise on how to remove the requirement to Activate Microsoft 365, and allow me to use the Office Home & Business 2021 that I purchased.

It seems that you are encountering an activation issue with your Office Home & Business 2021 for Mac, which is prompting you to activate Microsoft 365 instead. Here are some steps you can take to resolve this issue: Sign Out and Sign Back In: Open an Office app (like Word or Excel), go to your name or profile picture at the top, select Sign out, and then sign back in using the account associated with your Office Home & Business 2021. Check for Updates: Ensure that your Office applications are up to date. You can check for updates in the app under Help > Check for Updates. [---] License Verification: Make sure that your Office Home & Business 2021 license is still valid and properly activated. You can check this in the Office app under Account. Contact Support: If none of the above steps work, you may need to contact Microsoft support for further assistance, as they can help you verify your license and resolve any account-related issues.

I do not see my name or profile picture at the top of the app.

I updated applications, and this did not solve the issue.

Reinstall Office - I will do this as a last resort.

License verification - Under Account, I do not see "Office App" to check license. But the license worked yesterday, and stopped working today with no changes on my end.

Contact support - is this not what I'm doing with this question?

Is reinstalling Office the only solution? That seems time consuming, and I've already wasted enough time trying to problem solve an issue that I did not create.

The AI responses to questions are often less than helpful (and sometimes dangerous). They are intended to give people quick responses, but not necessarily useful or accurate responses.

Despite how MS makes it look, you are in a user-to-user support forum. The people responding to questions are your fellow users, usually very experienced users. John Korchok would be included in that category. So would Bob Jones if he responds.

Microsoft is not hearing about your problems from what you post here. You are discussing a problem with your fellow users here. We can give good advice about how to work with Word as it is and give suggestions for making it work properly.

Designers and their supervisors do see feedback. (You will almost certainly not get a direct response to that feedback but they do see it.)

I've been seeing more reports of this "disappearing license" problem. If you have to reinstall, you can find the installer on the Subscriptions page of your Microsoft account. It already has your product key associated with it. After installation, signing in to your account in any of the programs will reactivate the software.

John,

Thank you for the response.

I installed updates, but that did not work.

I reinstalled from my subscriptions page, but that did not work.

If I uninstall on my Mac, the instructions say to move all Microsoft applications to Trash, move the folders below to Trash, restart, and reinstall.

I just want to verify that I won't be losing any important data. You noted that my product key is associated when installing from my Microsoft account, so I assume there are no issues with that.

Thank you again for the response, and here are the folders instructed to delete as part of the uninstallation:

Microsoft Error Reporting

Microsoft Excel

com.microsoft.netlib.shipassertprocess

com.microsoft.Office365ServiceV2

Microsoft Outlook

Microsoft PowerPoint

com.microsoft.RMS-XPCService

Microsoft Word

Microsoft OneNote

None of the listed folders have important data, but you may lose items like the list of recently opened documents. If you have custom macros, styles or AutoText, it's prudent to save a copy of your Normal.dotm template. It is stored in the same use Library folder as the folders that should be deleted. The path to Normal.dotm is ~/Library/Group Containers/UBF8T346G9.Office/User Content/Templates.

John,

Thank you for your continued help. It ultimately began to work, and I'm not really sure how. I did a combination of some of the steps you provided, though some of the folders and files did not exist. Nothing was working, and then somehow it eventually did work.

Anyhow, I'm happy I can use Office again, and I appreciate your assistance.

In one-time-purchases of Office, you do not need to be signed in, so Step 1 isn't relevant.

For step 4 in Word for Mac, choose Word>About Microsoft Word. The dialog that opens should show you Microsoft account email address beside Belongs to:. Click on More Info, then on Refresh License, Word will ask you to sign in, after which it will hopefully reconnect your account with your installation.

If that doesn't fix it, try creating a new user account (System Settings>Users & Groups), signing in to that, then testing if the problem still exists. If it goes away, it's an issue with the user profile part of your Office installation.

If the issue still exists, or you'd rather not move your user data to a new profile, then uninstall Office following these steps: Uninstall Office for Mac Then reinstall from the Subscriptions page of your Microsoft account.

@Penny Searles

This is an old thread, so it is probably a different issue being discussed here.

Microsoft states that the October 2026 issue with Office 2021 licensing on macOS should be fixed by version 16.114.3. See https://learn.microsoft.com/en-us/officeupdates/release-notes-office-for-mac .

You can install version 16.114.3 from the update history page at https://learn.microsoft.com/en-us/officeupdates/update-history-office-for-mac .

If you need further assistance, please start your own thread.

Good luck.

The current one is old and it will be closed.

It seems that you are encountering an activation issue with your Office Home & Business 2021 for Mac, which is prompting you to activate Microsoft 365 instead. Here are some steps you can take to resolve this issue:

Sign Out and Sign Back In: Open an Office app (like Word or Excel), go to your name or profile picture at the top, select Sign out, and then sign back in using the account associated with your Office Home & Business 2021.
Check for Updates: Ensure that your Office applications are up to date. You can check for updates in the app under Help > Check for Updates.
Reinstall Office: If the issue persists, consider uninstalling and then reinstalling Office. You can find instructions on how to uninstall Office for Mac and then reinstall it from the official Microsoft support page.
License Verification: Make sure that your Office Home & Business 2021 license is still valid and properly activated. You can check this in the Office app under Account.
Contact Support: If none of the above steps work, you may need to contact Microsoft support for further assistance, as they can help you verify your license and resolve any account-related issues.

These steps should help you regain editing capabilities in your Office applications without needing to activate Microsoft 365.
