Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
If the subscription is valid but Office opens in read-only mode, use this order:
- Sign in with the correct account in PowerPoint or another Office app.
- Office must be activated with the same Microsoft account, or work/school account, that was used to buy or subscribe to Microsoft 365.
- If the wrong account is used, Office can show activation messages such as not finding Office products.
- Verify the subscription is actually attached to that account.
- Go to Services & subscriptions at https://account.microsoft.com/services.
- The Microsoft 365 subscription or Office product should be listed there.
- If it is not listed, that account is not the one associated with the license.
- Check for multiple Office installs on the PC.
- Open Control Panel > Programs > Programs and Features.
- Search for office in the Programs and Features search box.
- If more than one Office version appears, uninstall the version not being used.
- Restart the PC.
- Open PowerPoint again and sign in if prompted.
- If Office is still not activated, run an online repair for the remaining Office installation.
- This is the next step after removing conflicting Office installs.
- If Office was preinstalled on the PC, confirm whether it was only a trial.
- On some new Windows devices, preinstalled Office requires starting a Microsoft 365 Family trial or buying Office to continue using desktop editing features.
- If purchase is already valid, activation still needs to be completed with the account that owns that subscription.
- If a product key was purchased separately, redeem it first.
- Go to Office.com/setup or https://microsoft365.com/setup and complete the one-time redemption so the product is added to the Microsoft account.
