Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
I’m sorry you’re having trouble accessing the subscription after already receiving the payment confirmation.
Could you first sign in to Services & subscriptions and check whether the subscription is listed as active? Make sure you use the exact Microsoft account associated with the purchase. If it is not listed, check any other Microsoft account you may have, since the payment and subscription may be connected to a different sign-in.
If it shows as active, please let me know:
- Where you see the “cannot connect to my account” message, such as Word, Excel, Outlook, or the Microsoft account website
- The exact error message or code
- Whether you use Windows, Mac, or a mobile device
For Windows Office apps, you can also open Word or Excel, select File > Account, sign out, and then sign back in using the account shown on the subscription page.
