Frequently Asked Questions

Why didn't I receive a product key for my Microsoft 365 subscription?

Modern Microsoft 365 subscriptions are managed digitally. Instead of a 25-character product key, your software license is directly linked to the Microsoft account you used to purchase it. Signing in acts as your key.

Can I use Excel on Mac without an active subscription?

Without an active subscription or a one-time activation, Excel on Mac operates in 'reduced functionality mode'. While you can still view and print your documents, you will not be able to create new files or save any edits.

How do I check which account is linked to my Excel subscription?

You can verify your subscription status by signing in to the Microsoft account website (account.microsoft.com) using a web browser. Navigate to the 'Services & subscriptions' tab to see which active licenses are tied to your email address.
