When you open Copilot in Microsoft 365 apps like Word, Excel, or Teams, you may see the error message “Not available for this account.” This means your current Microsoft 365 account does not have the required license or the Copilot feature is not enabled for your tenant. The issue is almost always caused by an incorrect license assignment, a missing service plan, or a sign-in state mismatch between your work account and the app.
This article explains the three root causes of this error and provides step-by-step fixes you can apply as an end user or an admin. You will learn how to verify your license, switch accounts, and check admin settings in the Microsoft 365 admin center. By the end, you will be able to resolve the “Not available for this account” message and start using Copilot in your daily workflow.
Key Takeaways: Fixing Copilot Not Available for This Account
- Microsoft 365 admin center > Billing > Licenses: Verify that the user has a Copilot license assigned and that the service plan is enabled.
- File > Account > Switch Account in Office apps: Sign out and sign back in with the licensed work or school account to refresh the token.
- Admin center > Settings > Org settings > Copilot: Check that the Copilot feature is turned on for the entire tenant and not restricted by a conditional access policy.
Why Copilot Shows “Not Available for This Account”
The error occurs when the Microsoft 365 application cannot verify that your account holds an active Copilot license. Three technical conditions cause this failure.
Missing or Expired Copilot License
Copilot requires a paid add-on license such as Copilot for Microsoft 365 or Copilot Pro. If your tenant administrator has not purchased the add-on or has not assigned it to your user account, the app will reject your sign-in attempt. The license may also expire if the subscription payment fails or the trial period ends.
Service Plan Disabled for the User
Even when a license is assigned, the Copilot service plan inside that license might be disabled. In the Microsoft 365 admin center, each license contains multiple service plans. An admin can turn off individual services like Copilot, Exchange Online, or Teams. If the Copilot plan is off, the user sees the “Not available” error.
Signed In with a Personal or Wrong Account
Copilot for Microsoft 365 works only with work or school accounts. If you are signed into the Office app with a personal Microsoft account like Outlook.com or a different work account that lacks the license, Copilot will not load. The app caches the last sign-in token and may not prompt you to switch automatically.
Steps to Fix Copilot Not Available for This Account
Use the following steps in order. Test Copilot after each step to see if the error clears.
- Sign out and sign back into Office apps
Open any Microsoft 365 app such as Word or Excel. Go to File > Account. Under User Information, click Sign Out. Close the app completely. Reopen it and click Sign In. Enter your work or school email address that has the Copilot license. This forces the app to refresh the authentication token and recheck license eligibility. - Verify your Copilot license in the Microsoft 365 admin center
If you are an admin, go to admin.microsoft.com. Navigate to Billing > Licenses. Select the Copilot license product. Under the Assigned Users tab, find your account. Confirm that the status shows “Assigned” and that the Copilot service plan is toggled On. If it is Off, click the toggle to enable it and save the change. - Enable Copilot for the entire tenant
In the admin center, go to Settings > Org settings > Copilot. Ensure the toggle for Allow Copilot for all users is set to On. If you see a specific security group restriction, verify that your account is a member of that group. Save the settings and wait up to 15 minutes for the change to propagate. - Clear Office cached credentials
Open Control Panel > User Accounts > Credential Manager. Click Windows Credentials. Scroll down to the Generic Credentials section. Remove any entry that contains “MicrosoftOffice” or “Microsoft.AAD.” Restart the Office app and sign in again. This clears stale tokens that may block the license check. - Check conditional access policies in Entra ID
If your organization uses Azure AD conditional access, a policy may block Copilot for certain users or locations. Ask your admin to review Entra admin center > Protection > Conditional Access > Policies. Look for any policy that targets the Copilot cloud app and ensure your account is not excluded or blocked. Disable the policy temporarily for testing.
If Copilot Still Shows the Error After the Main Fix
Copilot works in one app but not in another
This usually means the Office apps are running different versions. Open each app and go to File > Account > About [app name]. Ensure the version number matches across all apps. If one app is on an older build, update it through File > Account > Update Options > Update Now. Copilot requires Microsoft 365 apps version 2302 or later.
Copilot shows availability but returns generic answers
This is not the same error. If Copilot loads but gives vague responses, the issue is data access rather than licensing. Go to the Copilot pane and click the Settings gear icon. Under Data sources, confirm that “Microsoft Graph” is enabled. If it is turned off, Copilot cannot read your tenant’s files and emails.
Copilot license appears assigned but error persists
The license assignment may not have synchronized with the Microsoft 365 authentication service. Wait 30 minutes and repeat Step 1. If the error continues, ask your admin to remove the Copilot license from your account, save the change, wait 10 minutes, and reassign it. This forces a fresh license provisioning cycle.
| Item | Copilot for Microsoft 365 | Copilot Pro |
|---|---|---|
| Target user | Business and enterprise users with work or school accounts | Individual users with personal Microsoft accounts |
| Required subscription | Microsoft 365 E3, E5, Business Standard, or Business Premium plus add-on | Microsoft 365 Personal or Family plus add-on |
| App integration | Word, Excel, PowerPoint, Teams, Outlook, Loop, Whiteboard | Word, Excel, PowerPoint, OneNote |
| Tenant admin control | Full admin control via admin center and conditional access | No tenant-level controls |
| Data grounding | Microsoft Graph data: files, emails, calendar, chats | Public web data and local files only |
Now you can identify whether the “Not available for this account” error is due to a missing license, a disabled service plan, or a mismatched sign-in account. Start by signing out and back into your Office apps. If the error persists, ask your admin to verify the Copilot license assignment and tenant settings in the Microsoft 365 admin center. For ongoing reliability, check the Copilot service plan toggle under each user’s license at least once a quarter.
