Contact Microsoft Support while signed in with the account that purchased Microsoft 365, then select Contact Support after Get Help to reach the available live-agent option.
Reach a support agent
- Open Contact Microsoft Support.
- Sign in with the personal Microsoft account used to purchase the subscription.
- Enter Copilot stopped working on three computers — check subscription entitlement.
- Select Get Help.
- If the automated suggestions do not resolve it, select Contact Support.
- Choose Microsoft 365 and Office → Manage my subscription.
- Select the offered live-support method, normally web chat; a callback may also be offered depending on region, product, and support availability. Microsoft 365 home subscriptions include technical support through chat at no extra charge.[^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft 365 Personal, Family, Premium, and Pro subscription benefits")
Because your previous chat disconnected, start a new request while signed in and include the earlier queue disconnection in the description. This Microsoft Q&A forum cannot access your account, subscription entitlement, billing records, or issue a refund.
Before changing all three computers
Copilot failing on three computers on the same day points to an account entitlement or service-side issue rather than three independent installations.
- Check Microsoft’s public service-health page for an active Microsoft 365 or Copilot incident.^2^
- If no incident is shown, refresh the Copilot license on one computer:
- Open Word, Excel, or PowerPoint.
- Go to File → Account.
- Confirm it shows the purchasing Microsoft account.
- Select Update License.
- Close every Microsoft 365 application and reopen one.
On a Mac, open the app menu → About <app name> → More Info → Refresh License, then restart the Microsoft 365 apps.^3^
- If Copilot still fails, open the Windows Get Help app and run:
- Copilot License Troubleshooter if Copilot is missing or says it is not licensed.
- Copilot connectivity troubleshooter if it cannot connect.^4^
Give the support agent the exact error message, subscription name, affected apps, and confirmation that the problem occurs on three computers. Ask the agent to check the Copilot entitlement and license status on the purchasing account.
If you prefer a refund
For a subscription bought directly from Microsoft:
- Sign in to Services & subscriptions with the purchasing account.
- Find Microsoft 365 and select Manage → Cancel.
- The cancellation process will automatically display whether it qualifies for a refund before you complete it.
Not every cancellation produces a refund. In most cases, the standard window is within 30 days of the initial purchase or before the first recurring billing date, whichever comes first. Some countries or regions allow prorated refunds under different rules.[^5^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")
Since the purchase was approximately three months ago, do not cancel unless you actually want to end the subscription; first ask the agent whether your purchase and region qualify. If no refund is issued after cancellation, Microsoft 365 access normally continues through the current paid billing period.
If the subscription was purchased from Apple, Google Play, Amazon, Best Buy, or another retailer, that seller—not Microsoft—must handle cancellation and the refund because it received the payment.[^6^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Manage your Microsoft 365 subscription purchased through a third party | Microsoft Support")
