Frequently Asked Questions

Do I need to uninstall Microsoft 365 before installing Office 2021?

Yes. Leaving Microsoft 365 installed can cause activation and compatibility conflicts. You should completely uninstall it via Windows 'Apps & features' before downloading and installing your Office 2021 lifetime license.

What if Office 2021 is missing from my Microsoft 'Services & subscriptions' page?

This usually means you are logged into the wrong Microsoft account, or the software was never properly linked during the initial laptop setup. You may need to use Dell Digital Delivery or contact Dell Support to retrieve the OEM entitlement.

Will my lifetime Office 2021 license activate automatically if I just cancel Microsoft 365?

No, it will not downgrade automatically. Microsoft 365 and Office 2021 are separate installations. You must remove the subscription-based software and explicitly reinstall the Office 2021 version from your Microsoft account.
