Indicator for new email with "new" Outlook in Windows 11

Is there a application or something I can run that will give me a visual indicator if I get a new email in the "new" version of Outlook on Windows 11?

The old version used to change the Outlook icon on the task bar to one with an envelope on it so that I knew that there was new email to read. The "new" Outlook doesn't seem to do that anymore. Is there a third party app that fills this need?

Currently I have to remember to periodically check Outlook to see if any new emails came in.

Thanks.

    Hi NickS,

    Welcome to the Microsoft Q&A forum.

    Based on your description, I understand that you would like the Outlook icon on the taskbar to display a small envelope when a new email arrives, indicating that you have received new mail.

    Normally, when you receive a new email, New Outlook will display a notification.

    For example, you may see an envelope icon in Outlook Desktop.

    If you are not receiving these notifications, please check the following:

    1. Check your Outlook settings

    Go to Settings > General > Notifications.

    Please make sure that Outlook notifications are enabled.

    Under the Mail section, verify that the Show an envelope icon in the taskbar option is turned on.

    1. If you have confirmed that all the settings above are enabled, try clearing the New Outlook cache.

    To clear the New Outlook cache, you can follow the instructions provided in the article below:

    1. Try uninstalling and reinstalling New Outlook.

    After reinstalling, please check whether the issue persists.

     I hope this information is helpful.

    New Outlook for Windows supports desktop alerts, but the provided information does not show a built-in taskbar envelope indicator for new mail in new Outlook, and it does not identify any supported third-party app for that purpose.

    A supported option is to turn on desktop notifications in new Outlook:

    1. Open new Outlook.
    2. Go to View > View Settings.
    3. Select General > Notifications.
    4. Under Notify me about, turn Mail on.

    New Outlook also supports notification sounds:

    1. In Notifications settings, go to Mail.
    2. Under New Email or Reactions, use Play Sound to choose a sound.

    If the goal is a persistent visual indicator similar to classic Outlook’s taskbar envelope, the available information only confirms desktop pop-up alerts in new Outlook. If that workflow is essential, switching back to classic Outlook is the documented workaround mentioned in related support guidance.
