You want to be informed. You will find your personal settings for this in the InfoLog settings:
There you have to see what corresponds to your wishes.
Of course, this can only work if the task has a due date.
In the list view, the date should also be displayed in red if the target date is exceeded. In combination with filters (over due … / => Favourites) you can also get an overall view quite quickly.
E-mails can easily get overlooked and the notifications in EGroupware (top right) are also often overlooked.
