Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello,
Do you remember all three email addresses you created?
If not, you can use the 'Recovery email address' to find your username (email address) using the link below.
https://account.live.com/username/recover
- Enter the recovery email address associated with your Microsoft Account.
- Then, Microsoft will send you a confirmation code.
- Enter the verification code; you will then be shown a hint of the email address associated with it.
Once you're able to recall/locate the email address,
- Sign in with your Microsoft Account on the Services & Subscriptions page here: https://account.microsoft.com/services
- If you have an active Office 365 Subscription, select the subscription, then click Manage, and then select 'Cancel Subscription'.
Open the link in an InPrivate Window.
Sign in with the Microsoft account on which you want to cancel the subscription, one by one, using the link above.
Let me know if you still need more help.
