co-pilot not working

Follow these steps to get Copilot working after upgrading to Microsoft 365 Premium:

1. Confirm the correct account and license
   • In any Microsoft 365 app (Word, Excel, PowerPoint, Outlook), check the account shown at the top-right or under File > Account.
   • Ensure that this is the account that has the Microsoft 365 Premium (Business Premium) or other eligible Copilot license assigned.
   • If multiple accounts are signed in (work/school + personal), sign out the non-licensed account so the licensed account is the primary one.
2. Make sure the apps are up to date
   • On Windows, install the latest Office updates as described in Install Office updates (from the Copilot button article). Copilot requires a recent build.
3. Refresh the license in the desktop apps
   • Windows:
     1. Open any Microsoft 365 app.
     2. Go to File > Account.
     3. Select Update License.
     4. Close all Office apps and reopen them.
   • Mac:
     1. Open any Microsoft 365 app.
     2. From the top menu, select <App name> > About <App name>.
     3. Select More Info….
     4. Select Refresh License.
     5. Close all documents and restart all Microsoft 365 apps.
4. Check privacy/connected experiences (Mac)
   • In Word, go to Word > Preferences > Privacy.
   • Turn on Experiences that analyze your content.
   • Scroll down and turn on All connected experiences.
   • If the device is managed by an organization, an admin may control these settings.
5. Check for common causes if Copilot is missing or greyed out
   • Newly assigned license: It can take some time for a new Copilot license to propagate; wait and try again later.
   • Licensing/account conflicts: If both personal and work/school accounts are signed in, Copilot may not validate correctly. Use only the licensed account.
   • Device-based licensing: Copilot is not available with device-based licensing; a user-based license is required.
   • Update channel: Copilot requires Current Channel or Monthly Enterprise Channel; Semi-Annual Enterprise Channel does not support it.
   • Privacy settings: If connected experiences are disabled, Copilot can be blocked.
6. If Copilot still does not appear
   • Follow the full steps in How to find and enable missing Copilot button in Microsoft 365 apps.
   • If using a work or school account, ask the Microsoft 365 admin to verify:
     • A license that supports Microsoft 365 Copilot is assigned.
     • Copilot is not blocked by organizational policies (for example, in Teams Admin Center or other app policies).
7. If license validation errors appear in the browser
   • Refresh the page where Copilot should appear.
   • Ensure third-party cookies are enabled in the browser, as blocking them can prevent Copilot from validating the license.
8. If issues persist
   • Home users: After completing these steps, contact Support using the channel indicated in the Copilot license validation article.
   • Business users: Ask the Microsoft 365 admin to open a support ticket with Microsoft if Copilot still does not work after confirming licensing and policies.
