Assistance Needed to Remove Old Hacked Email and Update Microsoft Account

Keshia LeBlanc 0

Hello,

Thank you in advance for your assistance.

I'm trying to close an old email account that was hacked. Unfortunately, this email address is still linked to the Microsoft account I use to log in to my computer.

I have created a new email address and set it as the primary email address for receiving Microsoft security notifications. However, I'm having difficulty fully transitioning to the new account.

I attempted to switch my computer login to a local account, and that process was successful. However, when I tried to access my Microsoft account information, I was unable to sign in using my new email address and password. I also attempted to use a passkey, but that was unsuccessful. As a result, I had to switch back to my old email address to regain access to my Microsoft account.

To summarize, I need assistance with the following:

Remove my old, compromised email address from my Microsoft account.

Ensure my new email address is my primary Microsoft account email and remove the old address.

Update my computer login so I can sign in using my new Microsoft account without encountering any issues.

I want to ensure that my new account is properly set up and that I can safely remove the compromised email address without losing access to my computer or Microsoft services.

I apologize for the lengthy explanation, but I wanted to provide as much detail as possible to help clarify my situation.

Thank you again for your time and assistance. I appreciate any guidance you can provide to help me resolve this issue.

Use the existing Microsoft account and change its aliases and security info. Do not create a separate new Microsoft account if the goal is to keep the same subscriptions, settings, storage, and sign-in identity, because aliases on one Microsoft account share the same account data and password.

Sign in to Edit account info and manage aliases:
- Open Edit account info
- Select Add email to add the new address if it is not already added as an alias.
- Select Remove next to the old compromised address when removal is available.
Keep the new address as the main sign-in/contact path:
- Email addresses on a Microsoft account are aliases.
- Aliases use the same contacts, storage, subscriptions, and account settings.
- Verification codes sent by email can only be sent to the primary alias or another email added as a way to verify sign-in.
Update security verification methods separately from aliases:
- Go to the Microsoft account Security basics page and update security info.
- If the old hacked email is listed as a verification method, remove it from Security settings or Security info after adding a replacement method first.
- If prompted for a code and the old method is inaccessible, choose I don't have any of these and follow the process to replace security information.
Important removal warning:
- If all security information is removed, the account can enter a 30-day restricted state.
- During that period, further changes or additions to security settings or billing information are not accepted.
- To avoid that, add the new security method first before removing the old one.
If the old address was compromised, secure the account before removing anything:
- Run a full malware scan on the PC.
- Then change or reset the Microsoft account password.
- After that, review account settings such as connected accounts, forwarding, and automatic replies.
For Windows sign-in:
- Since the PC was already switched to a local account successfully, access to the computer is preserved.
- After the Microsoft account alias/security changes are complete, sign back in with the same Microsoft account using the updated sign-in information.
- If sign-in still fails with the new address, continue using the old alias only long enough to finish alias/security changes, then remove the old alias after the new one is fully established.
If sign-in or removal is blocked:
- Use the sign-in helper or guided support tool.
- Microsoft support can route the case, but support agents cannot send password reset links or directly change account details.

Hello Keshia LeBlanc,

The new email address needs to be added as an alias of the same Microsoft account, rather than being set up as a separate Microsoft account. Aliases share the same password, subscriptions, storage, and account data, and an enabled alias can also be used to sign in to Windows.

Before removing the old address, I recommend checking the following:

Open Manage how you sign in to Microsoft and confirm that the new email appears as an alias and is marked as the primary alias.
Under Change sign-in preferences, make sure the new alias is allowed to sign in.
Sign out of the Microsoft account online, then test signing in again with the new alias and the existing Microsoft account password.
Once the new alias works, reconnect Windows to the same Microsoft account using the new alias.

As a safer first step, you can disable sign-in for the compromised alias instead of removing it immediately. This prevents that address from being used to access the account while allowing you to verify that the new alias works correctly. Microsoft provides the steps here: Block an email address from signing in.

Also check the Security section of the account separately. If the compromised address is listed as a verification method, add and verify a replacement method before removing the old one.

If the new alias is listed correctly but is still not accepted, use the Microsoft account Sign-in Helper. It can identify the available recovery or support options for the account.

I would avoid removing the old alias until both the online sign-in and the Windows sign-in have been successfully tested with the new one. Thank you so much for your understanding.
