• Browser problems (if using Microsoft 365 online)

How to fix Copilot not working error in Microsoft Office

Microsoft Office has two main versions: Home and Microsoft 365. How to handle errors will depend on the type of product people are using. With Microsoft 365 (which includes Copilot in the subscription and runs directly in the browser), users can try the following:

Check your subscription

If Copilot is not working, the first thing users need to do is check to see if their Microsoft 365 or Copilot package is still valid with the following steps:

Step 1: Sign in to your Microsoft account using any browser.

Step 2: On the home page, click the tab Subscriptions in the sidebar to see active plans.

Step 3: If you see your Copilot or Microsoft 365 plan has been canceled or expired, click Resubscribe to reactivate.

Check your login account

It sounds simple, but this is a very important step. Look in the top right corner of any Office application on your computer to confirm that you are signed in to the correct primary account. If you have multiple accounts, make sure you’re using an account with an active Copilot plan.

Update Office

Although Microsoft Office usually updates automatically, users can still check manually to make sure the software is not corrupted due to an old version.

Step 1: Open any application (for example: Word, Excel) and tap File.

Step 2: Select Account in the sidebar.

Step 3: Press Update Options > Update Now.

Step 4: Office will automatically check for and install the latest updates.

Turn off add-ins (additional utilities)

If Copilot is not working in a specific application (such as Word), it may be due to a conflict with the Add-in. Try turning them off in the following way:

Step 1: Press File > Options.

Step 2: In the new window, select Add-ins.

Step 3: At the bottom of the window, select Manage: COM Add-ins > Go.

Step 4: Turn off each Add-in in turn and then press OK.

Step 5: Restart the application to see if Copilot is working.
