    Hi Joanne Harvey,

    I understand that an email sent from your son’s PC appears to come from your Outlook account, and you want to separate the accounts.

    The Q&A Assist answer is correct that the selected From address should be checked. Have you had a chance to try that? Before removing or changing any account address, could you confirm whether the received message shows your actual email address or only your name?

    I would also like to add that your Outlook.com account may still be signed in on that PC. On your son’s PC, open Outlook.com, select the profile picture or initials in the upper-right corner, and choose Sign out. Then close all browser windows and have your son sign in with his own Microsoft account. Microsoft also recommends using separate computer accounts when several people use the same PC. Sign out of Outlook.com

    Please do not remove an Outlook alias yet, as aliases can belong to the same Microsoft account and share its password and account information.

    Alos be advised that this is a user-to-user forum, so contributors cannot access or separate the accounts directly. Once you confirm the address shown in the From field, the appropriate next step can be identified.

    This usually means one of these is happening:

    1. The same account is being used to send mail on both PCs.
    2. There is a forwarding or mail rule causing messages to behave unexpectedly.
    3. The address is being spoofed rather than actually sent from your account.

    Try these checks in Outlook.com:

    1. Open Sent Items in the account that appears as the sender.
      • If the message is in Sent Items, that account likely sent it.
      • If it is not there, spoofing is more likely.
    2. Check mail rules. Go to View all Outlook settings > Mail > Rules.
      • Remove or disable any rule that forwards, redirects, or automatically replies in a way that was not set up intentionally.
    3. Check forwarding. Go to View all Outlook settings > Mail > Forwarding.
      • Make sure forwarding is turned off, or remove any incorrect address.
    4. If the same email address is attached to both a personal Microsoft account and a work or school account, rename the personal Microsoft account by changing its primary alias. Microsoft states this can stop account confusion when the same email address is used by two Microsoft accounts. Use Manage sign-in preferences or the Microsoft account Manage how you sign in page to make another address primary.
    5. If the goal is to remove an address from a Microsoft account, go to Your info and choose Remove next to the existing address, or add a different address first and make that one primary.

    If the issue is only that mail appears to come from the wrong person on one PC, also verify that the correct account is selected in the From field when composing a message.
