We have a user that when they get a new email has the usual prompts and notifications. However when they click on the Outlook inbox or another email that has already been read, the envelope icon disappears.
I've already looked in the settings and can't find anyway to extend or change the amount of time that the envelope stays visible.
Most posts I've found are trying to either trying to remove or add the notification. The notification is there and stays until you interact with the inbox.
Any help greatly appreciated.
