I have 2 Microsoft accounts. How do I delete one???

First check whether the two email addresses are aliases of one Microsoft account; only close an account if signing in with each address actually opens a different account.

1. Check whether they are aliases

1. Open the Microsoft account Manage how you sign in page:
   https://account.live.com/names/manage
2. Sign in with one of the email addresses.
3. Review the addresses listed under Account aliases.

Aliases are different sign-in addresses for the same account and share its password, contacts, storage, subscriptions, and settings.^1^

• If both addresses appear there: You have one account, not two. Select Remove beside the unwanted alias instead of closing the account.
• Important: Removing an @outlook.com, @hotmail.com, or @live.com alias can permanently delete that address, so do not remove it if you might need it later.
• If only one address appears: Sign out, preferably open a private/incognito browser window, and sign in with the other address. If it opens different email, storage, subscriptions, or account details, they are separate accounts.

Using the same mobile number does not make two separate accounts into one account.

2. Prepare the account you want to keep

Before closing the unwanted account:

1. Sign in to the account you intend to keep and confirm its email address and password work.
2. Check the unwanted account for anything needed from Outlook.com, OneDrive, Xbox, Skype, subscriptions, or saved BitLocker recovery keys.
3. Save or move anything important before proceeding.

Closing an Outlook.com address means closing its entire Microsoft account. Its email and contacts are deleted, and access to other Microsoft services connected to that account is lost.^2^

3. Close the unwanted account

1. Open Microsoft’s account-closure guidance and select the option to start closing the account.^3^
2. Sign in using the email address of the account being deleted.
3. Verify that the closure page displays the correct account.
4. Select Next.
5. Read and acknowledge each closure warning.
6. Choose a 30-day or 60-day reopening window.
7. Select a reason, then choose Mark account for closure.

The account’s data is deleted after the selected reopening period expires. If the security information was recently reset, Microsoft requires a 60-day wait before the account can be closed.^3^

If you cannot sign in to the unwanted account, use the Sign-in helper linked from the closure article; account closure requires successful sign-in.
