how do I know if I have 2 microsoft 365 accounts

To check whether there are multiple Microsoft 365 subscriptions being charged, use these steps:

1. Check subscriptions for each Microsoft account
   • Go to the Subscriptions page: https://account.microsoft.com/services
   • Sign in with the Microsoft account (email and password) normally used with Microsoft 365.
   • Under Subscriptions, review the list and note any active Microsoft 365 subscriptions and their renewal dates.
   • Repeat this process for any other email addresses that might be used as Microsoft accounts (for example, personal, work, school, or older addresses). Each Microsoft account can have only one active Microsoft 365 for home subscription, but different accounts can each have their own subscription.
2. Check for duplicate or unexpected charges
   • Review recent bank or credit card statements for Microsoft charges.
   • Sign in to the order history for each Microsoft account and compare against the bank statement to see which account each charge belongs to. Use the guidance in I've been charged twice to understand if charges are actually duplicates or just close together in time.
   • If multiple accounts (for example, a family member’s account) are using the same card, there may be charges from more than one Microsoft account on the same payment method.
3. Use the billing investigation tools
   • Go to the Manage your payments page of the Microsoft account dashboard and select Investigate next to the payment method in question. This helps identify which account and which subscription a charge belongs to.
4. Decide which subscription to keep
   • Once it is clear which accounts have active Microsoft 365 subscriptions, sign in to the account whose subscription is not needed and cancel it from the Subscriptions page so that future renewals stop. Canceling a subscription does not delete the Microsoft account itself.

If charges are still unclear or appear incorrect after these checks, contact Microsoft Billing Support from the support pages in the references so an agent can review account-specific billing details.
