For some reason, my Microsoft Outlook 365 desktop application is not showing desktop notifications for new mail. Does Outlook 365 need to be open in order to show the notifications? I would guess not but if so that’s the issue.
Otherwise, what else could be the issue? Below, I’ve listed what I’ve tried so far. I installed this earlier today so I haven’t messed with any other settings.
1) All Settings > System
From the panel on the left select: Notifications & Actions.
In the “Get notifications from these senders” section at the bottom, click on Outlook.
Make sure that you have enabled all notification options.
Close Settings
2) File > Options > Mail.
Under Message arrival, select Display a Desktop Alert check box and then select OK.
