Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Greetings!
This is Tin, looks like you have 2 subscription with 2 accounts, and you would like to cancel the other one but you can't access it anymore. What is the error message that you're getting when trying access it? Have you tried to reset the password already? If not, you can do it from here:
https://account.live.com/ResetPassword.aspx
In case you're unable to recover it, it would be best to reach the MS Accounts & Billing to check on it:
Kindly open this link: https://support.microsoft.com/en-us/contactus/
Ensure that your MS Account has been signed in (You can use the other account for now since you don't have access with the other one)
Type "Chat with an agent" and hit Enter.
Please click the "Contact support"
Please select the "Products and services"
Please follow the prompts to connect with a live agent.
You may also choose the "Call me back" option if you prefer to receive a call.
Once you're connected to the Live Agent, please let them know about your issue so they could check your account and address your concern.
Thank you,
Christine
