Windows 10 Enterprise LTSC 1809 and Outlook 2016

Andrei Corovin 101 Reputation points


I have a question regarding Windows 10 Enterprise LTSC 1809.

I see that users can use "Display a Desktop Alert" feature in Outlook 2016 on Windows 7 (Home, Pro, Entreprise) and Windows 10 Enterprise 1903 machines, but not on Windows 10 Enterprise LTSC 1809 machines. The pop-up doesn't appear!

Is this a known issue?

P.S. As far as I understand, the limitation or bug is related to Windows10 Enterprise LTSC 1809, right?

    Hi @Andrei Corovin ,

    but not on Windows 10 Enterprise LTSC 1809 machines. The pop-up doesn't appear!

    Did this issue happen to all users working with Windows 10 Enterprise LTSC 1809?
    And did it occur with all messages sent to all mailboxes in your Outlook client?

    Based on my research, there seems to be no related known issue in the list of Windows 10 Enterprise LTSC 1809, but as I know, certain settings in Outlook and Windows may affect the feature of desktop alert, please first try to troubleshoot by the steps below:

    • Firstly, it is worth mentioning that if the issue only occurred during the initial synchronization of an email account or when you request a manual Send/Receive, it's by design as the official article mentioned.
    • Also, in the point of Outlook client, only the messages sent to default Inbox could display the desktop alert by default, please first check if the issue only happen to any specific messages that was moved to other folders by client rules.
    • Then, the feature could also be affected by the setting in Outlook, please check if you have enabled this feature by the steps below(File>Options>Mail>check "Display a desktop alert" option under the message arrival)


    • If the issue still exists, it's suggested to check if you have enabled the notification of Outlook in Windows settings(Start>Settings>System>Notifications & actions > Outlook)


    Hope that would be helpful to you and if your issue has any update, please feel free to post back.

    Windows 10 Enterprise LTSC 1809 is intended for use by device manufacturer who are building dedicated embedded/IoT systems. It is not intended for general purpose use. Pieces of Office can be installed for use with these dedicated systems, but not for general purpose use. Some items might be disabled or set differently in LTSC 1809.

    Are you building a dedicated embedded/IoT System? Or are you building a general purpose computer and are using LTSC as a way to get around 6 month updates?
