Activate my Account

Contact Microsoft Support through the Get Help flow and request an agent for Microsoft 365 activation and billing.

Contact a support agent

1. Open Microsoft customer support.
2. Select Personal account, then Get help under Microsoft technical support.
3. Sign in with the same Microsoft account showing the June 2027 renewal date.
4. Enter: “Microsoft 365 subscription is active, but Excel activation spins indefinitely and editing is disabled.”
5. Complete the initial prompts, then select Contact Support when offered.
6. Choose Microsoft 365 and Office → Activation, then select an available option such as Chat. The same page also lists regional telephone numbers if chat is unavailable.^1^

Have these items ready:

• The email address associated with the subscription—do not post it publicly.
• A screenshot of Excel’s activation notice.
• The purchase date and order confirmation.
• The device type and operating system.
• Any exact error code, if one appears.

Support agents cannot access or change account details or send password-reset links, but they can assist with Office activation and account/billing issues.^1^

Try this recovery option while waiting

Since the subscription already shows a June 2027 renewal date, do not purchase it again.

On Windows 10 or Windows 11:

1. Close Excel and all other Office applications.
2. Open Microsoft’s Microsoft 365 troubleshooters page.
3. Under Microsoft 365 activation troubleshooter, select Start.
4. Allow the browser to open Get Help.
5. Complete the prompts on the same PC where Excel is installed, then restart when prompted.^2^

This troubleshooter is specifically for Microsoft 365 subscription activation and requires Windows 10 or later.

On either Windows or Mac:

Check which account owns the license before changing or reinstalling anything:

1. Close all Office applications.
2. Open the Microsoft account Services & subscriptions page from Microsoft’s activation guide.
3. Sign in using the account that purchased Microsoft 365.
4. Confirm that the subscription is listed under Subscriptions, not Cancelled subscriptions.
5. Reopen Excel and sign in with that same account.^3^

If the subscription was purchased as a physical card or retail product key, payment alone may not complete activation—the key on the card or the link in the receipt must also be redeemed.[^4^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID]'re-still-getting-notifications-after-renewing-or-buying-microsoft-365 "A subscription notice appears when I open a Microsoft 365 application | Microsoft Support")

Until activation is restored, Microsoft’s guidance says Office on the web can be used in a browser to create and edit documents.[^4^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID]'re-still-getting-notifications-after-renewing-or-buying-microsoft-365 "A subscription notice appears when I open a Microsoft 365 application | Microsoft Support")
