Product key error messages and solutions

If you're getting this error message when you enter your product key...

Try this...

“The product key you entered isn’t valid. Try entering it again.” Or “This product key isn’t valid. Please enter a different product key.”

Carefully check the numbers and characters you are entering. Mistakes can be made with 0 and o, 5 and S, l and I, and so on. If the issue persists, please contact the reseller where you bought your product key.

“You have already entered this product key. Enter a different key.”

Check the product keys you already entered to see if the key has already been added. If you are renewing a subscription using a product key, you must use a new and unused product key.

Need to buy a new key? Visit the Microsoft Store or a third-party reseller, or—if you’re working with a partner—contact your partner.

If the issue persists, please contact Office 365 Support. If you are working with a partner, contact your partner for product key support.

"The product key you entered has expired. Enter a different key."

You must use a new and unused product key to renew a current subscription or activate a new subscription.

Need to buy a new key? Visit the Microsoft Store or a third-party reseller, or—if you’re working with a partner—contact your partner.

"This product key has already been used. Please enter a different product key."

Verify that the key hasn’t already been used by you or a member of your organization. If the key hasn’t already been used, please contact your partner or the reseller where you bought the product key.

"Sorry, we can’t process your request right now. Please wait a few minutes and try again."

If subsequent attempts result in the same error message for more than 15 minutes, please contact Office 365 Support.

“The requested subscription is not available. One of the following reasons could have caused this: The offer is not available - The service is not available in your country - It is impossible to use/select the same trial twice. If the issue persists, contact Microsoft support.”

Please contact Office 365 Support. If you are working with a partner, contact your partner for support.

"You’ve added more user licenses than this offer allows. The maximum is <x> user licenses. Remove this product key and enter one that adds fewer user licenses."

Please contact your reseller or partner. You have purchased more licenses than can be used with this Office 365 subscription.

"You must be a global or billing admin to redeem a product key."

Be sure your permissions are set as either billing or global admin. To verify this, Sign in to Office 365 with your work or school account and go to the Office 365 admin center.

In the admin center, select Users > Active users. In Filters, choose Global admins or Billing admins.

Ensure that you are listed in the results.

Note: When you buy Office 365 through a partner, Microsoft sends you an email containing instructions to get your product key and activate your subscription in the Volume Licensing Service Center. To learn more about Volume Licensing, see help for existing Volume Licensing customers.
