This is a little weird. I have a profile which I call 'Microsoft'. It has apps such as one drive and Outlook which I need for work. I have it set to send notifications to the current user. I am constantly getting a notification that says, 'Notification from Outlook for Microsoft'. When I switch users, Outlook never sent a notification about any new emails. Its a little strange/annoying because I never know if the notification is a real (and important) email, or just a dud notification.
