When I delete an email from my main folder, a notification pop up and sound activates as if I received a new email.

    Dear Lamboy-Caraballo, Rocio,

    This behavior is usually caused by Outlook generating a desktop alert when a message is moved or processed, rather than only when a truly new email arrives.

    Here are some suggestions you can try:

    1/In case you are using Classic Outlook

    Open Outlook.

    Select File > Options > Mail.

    Under Message arrival, review these settings:

    • Uncheck Play a sound
    • Uncheck Display a Desktop Alert

    Click OK.

    2/If the issue only occurs when deleting messages, try to check for the rules:

    • Go to File > Manage Rules & Alerts.
    • Review any rules that move, copy, or process messages when they are deleted.
    • Temporarily disable suspicious rules and test again.

    3/Check add-in

    Some third-party Outlook add-ins can trigger unexpected notifications.

    • Select File > Options > Add-ins.
    • Choose COM Add-ins > Go.
    • Disable non-Microsoft add-ins temporarily.
    • Restart Outlook and test.

    I hope it helps. Feel free to reach out if you have any other questions.
