I’m unable to sign out of the Microsoft account on my computer through Settings. This is causing problems when I try to sign in with the correct Microsoft account, because the device is still linked to an invalid email address. As a result, verification codes are being sent to an email address that no longer exists. Because I can’t receive these codes, I’m unable to access any Microsoft products, including Microsoft Project, which I’ve already purchased and I also can’t contact support.

    Hello Viego,

    Is the old email address you are trying to remove a personal Microsoft account or a work or school account? It is my previous business work email

    When you mentioned that verification codes are being sent to an email that no longer exists, are these codes for Microsoft Authenticator, or were they product‑related emails (such as a product key) previously sent to that account? Pass key, I believe. Not sure, the response is always, we sent a code to your email on file.

    How are you currently attempting to sign out? Are you receiving any specific error messages during the process? The is no option to sign out, this is one of my issues

    The AI response is inadequate and does not match my screen. The directions are useless
