Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi,
This usually happens when Microsoft 365 is not properly activated on the device, or when a different Microsoft account is signed in inside Word or Excel.
Since you mentioned you purchased two accounts, the issue is often caused by signing in with the wrong Microsoft account that does not have the active Microsoft 365 license.
To better help you and guide you to the right solution, could you please check and confirm the following details?
Go to https://account.microsoft.com/services then sign in to your account. Do you see Microsoft 365 subscription active there?
From Word or Excel, please go to File > Account, then check and share the exact full product name shown there.
Are you using a Windows or Mac device for the subscription?
