Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Use the email address shown on the Microsoft 365 payment receipt to identify the account that owns the subscription, then sign in to the Services page with that exact account before troubleshooting the new iMac.
1. Identify the account that received the payment
- Search every email account you use for the Microsoft 365 renewal receipt dated 21 September.
- Note the email address associated with that receipt. It may differ from the address currently being entered.
- Open https://account.microsoft.com/services and sign in with that address.
- Select Install Microsoft 365 or Office. The paid licence should appear on the resulting page. Merely seeing free web apps does not confirm that the account owns a subscription.^1^
If the username or password is not accepted, use Microsoft’s account-recovery options for a forgotten username, password reset, multiple accounts, or switching accounts.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft 365 for home")
2. If the subscription appears online but Office fails on the iMac
This means account access and Mac activation are separate issues. On the iMac:
- Quit Word, Excel, Outlook, PowerPoint, and OneNote.
- Download Microsoft’s Office licence removal tool.
- Open the downloaded
.pkgfile and select Continue. - Select Install and enter the Mac administrator password if requested.
- When it finishes, open Word or Excel.
- Sign in with the email address that showed the active subscription in step 1.
- Restart the iMac after activation.
The tool removes all existing Office licences from the Mac, so have the correct subscription email address and password available first.^3^
3. If Apple or another retailer collected the payment
Check the receipt to see who charged you.
- Apple/App Store purchase: verify that the subscription is active under the Apple ID used for the purchase, then use Restore Previous Purchase in Office. An Apple subscription can already be associated with a different Microsoft account.^4^
- Another retailer: contact that retailer about billing, refunds, or subscription management because Microsoft does not receive that payment directly.^5^
4. Reach a Microsoft support agent
Since the automated online check has already reported no problem, proceed to assisted support rather than running it again:
- Open Microsoft’s support page.
- Under Microsoft technical support, select Get help.
- Enter: “Paid Microsoft 365 subscription not accessible after moving to a new iMac.”
- Select Contact Support when offered.
- Choose Microsoft 365 and Office → Account and billing or Activation, then select an available chat or telephone option.
Microsoft states that the available route can include chat, while telephone availability and numbers depend on country or region.^6^
Have the payment date, receipt/order number, charged amount, and possible account email addresses ready. Do not post those details publicly.
