Solution 1Recommended

Verify your license status through Microsoft

Check your official Microsoft account portal to see the exact status and type of your Office 365 subscription.

Office 365 (now Microsoft 365) is exclusively a subscription-based service. Microsoft does not sell permanent 'lifetime' licenses for this product line. Accounts marketed as such are often unauthorized volume licenses, developer accounts, or educational accounts that eventually get flagged and deactivated.

Sign in to your Microsoft Account

Go to account.microsoft.com and log in with the email address associated with your Office 365 Pro Plus software.

2
Navigate to Subscriptions

Click on the 'Services & subscriptions' tab located at the top navigation menu to view your active services.

Frequently Asked Questions

Does Microsoft offer any lifetime Office licenses?

Yes, but not for Office 365 or Microsoft 365. Microsoft offers standalone, one-time purchase versions like Office Home & Student 2021. However, these standalone versions do not receive ongoing feature updates like the subscription plans do.

Why did my 'lifetime' license work for exactly a year before expiring?

Many unauthorized third-party sellers exploit Microsoft's developer program or promotional enterprise trials, which grant a free one-year subscription. Once the one-year promotional period ends, the account is automatically deactivated.

Can I renew the expired third-party Office 365 account?

If the account was an unauthorized organizational or volume-licensed account, you usually cannot renew it yourself. You will need to purchase a legitimate Microsoft 365 subscription from the official Microsoft store and potentially migrate your files to a new, personal account.
