Email notifications not working (KDE, Microsoft Exchange account)
I'm not getting notifications for received mail. Thunderbird 142 on Fedora Linux KDE, Microsoft Exchange email account. The emails arrive but I get no notification. Calendar notifications work fine.
In the settings I have enabled "Show an alert" when new messages arrive, and "Use the system notification". Unchecking "Use the system notification" does not help, still no notifications.
I think this is a critical issue, as I may miss important work emails.
Have not found any discussion or solution to the problem.
