When you receive a message through Microsoft teams you get a toast notification and the icon flashes. You can choose to have these notifications enabled or not. However, when the "banner" notification is disabled the toolbar icon does not flash at all.
Is there is a way to disable the toast notification but keep the flashing toolbar icon intact?
I have disabled all notifications in the Notifications settings within Windows 10, but the toast notifications are still showing.
This screenshot is to confirm that Microsoft Teams does not show up within the Notifications & Actions settings window:
The version of Teams I have installed is 1.1.00.10955 (64 bit). It was last updated on 04/05/2018.
There is now a suggestion on Microsoft's User Voice forum surrounding this feature. You can follow it here: https://microsoftteams.uservoice.com/forums/555103-public/suggestions/32624690-turn-off-message-preview-in-notification-toast
