How to Change an Incorrect Alternative Email on a Microsoft 365 Work Account

Product: Microsoft 365
Device & OS: not provided
Scenario: The user is attempting to verify or recover their account but is locked out because the alternative email address entered during the initial setup is incorrect or inaccessible.
Observed behavior: The authentication system attempts to send verification codes to an incorrect alternative email, preventing the user from completing the login or recovery process.

Before you start

Ensure you have access to any secondary registered sign-in methods, such as the Microsoft Authenticator app or a linked phone number, before attempting to update your security information.

Solution 1Recommended

Update Security Info via My Sign-Ins

Use this method if you still have access to at least one other verification method, such as an authenticator app or phone number.

Microsoft allows users to manage their security verification methods independently as long as they can successfully authenticate into their account using an existing method.

Log in to My Sign-Ins

Go to the Microsoft My Sign-Ins portal (mysignins.microsoft.com) and log in using your work account credentials.

Use an alternative verification method

When prompted to verify your identity, select 'Sign in another way' and choose an accessible method, like your Authenticator app or an SMS code.

Navigate to Security Info

Once logged in, click on the 'Security info' tab on the left-hand navigation menu.

Update the alternative email

Locate the incorrect email address in your list of methods. Click 'Change' or 'Delete', then follow the prompts to add and verify a new, correct alternative email address.

Verification Required: You will need immediate access to the new alternative email inbox to enter the verification code sent by Microsoft.

Solution 2

Request an Authentication Method Reset (For End Users)

If you are a standard user and do not have access to any other sign-in methods, you must contact your IT department.

Solution 3

Contact Microsoft Data Protection (For Sole Administrators)

Use this option if you are the only global administrator for your organization and are completely locked out of the tenant.

Frequently Asked Questions

Can I bypass the alternative email verification step?

No. For security purposes, Microsoft requires you to prove your identity using a registered authentication method before allowing you to view or change sensitive security information.

Why does Microsoft support send me to personal account recovery?

This happens if you do not explicitly state that you are using a Microsoft 365 business or work account. When calling support, you must clarify that you are a business tenant administrator to be routed to the Data Protection team.

How long does it take for a newly updated alternative email to become active?

Once you successfully update your alternative email via the My Sign-Ins portal and verify the new address, the change is typically active immediately for future login attempts and recovery codes.
