    The settings are as follows:

    SMTP Server smtp.office365.com

    Port 587

    Encryption STARTTLS

    Requires Authentication ✅ Yes

    Username Your full email address (******@live.co.uk)

    Password Your Microsoft password (or app password if using 2FA)

    For Certificate invalid fix:

    Make sure the SMTP server is not set to something like smtp.live.co.uk — that’s outdated.

    Change it to smtp.office365.com.
