The ability to get notifications with every new email message without opening the inbox is a very smart feature that is greatly appreciated by many of our customers.
It works both on Mac (appearing in Notification Center) and Windows PC (appearing as slider inside the application window)
How to enable the slider notifications?
Go to menu option Administration -> User settings -> Notifications and change the notification style into Slider - message.
Mac users should still allow notifications in their local Mac. Go to System Preferences; Notifications, scroll to SpinOffice and allow notifications there.
