New Message Envelope Icon and Desktop Alerts Are Not Displaying

[rspiet]

Hello, I use Outlook 2016 on my Windows 7 Professional work computer. I have the options checked for when a new message arrives to Play a Sound, Change the Mouse Pointer, Show an Envelope Icon in the Task Bar, and Display a Desktop Alert. These were all working normally until sometime Tuesday. Now, I do not get any notifications at all of a new e-mail. I did not change or do anything different. I have performed a Full Repair of Office, rebooted, but that did not help. Does anyone have any other suggestions?
