Frequently Asked Questions

Do I need a separate product key for OneDrive?

No, OneDrive does not typically use a separate product key. Any premium storage space is bundled with your Microsoft 365 subscription and is automatically activated when you redeem your Microsoft 365 key.

What should I do if my product key is returning an error?

Ensure you are typing the 25-character code correctly without hyphens. If you receive an 'already used' error, check your Microsoft account's 'Services & subscriptions' page to verify if the plan is already active.

Can I redeem my Microsoft 365 product key on the desktop app?

It is highly recommended to redeem the key online at microsoft365.com/setup first. Once the key is successfully linked to your Microsoft account online, you can simply log into the desktop applications to activate them.
