The pop-up desktop notification and sound for Outlook have stopped showing up on one of my computers. Desktop alerts and sounds are enabled in Outlook settings, notification from Outlook are enabled in Win10 notifications settings, new emails go to the inbox, and I'm not using quiet hours. Notably, when I first detected this issue, I discovered that Windows 10's notification settings had been disabled for Outlook at some point (AFAIK, I didn't do this). Re-enabling this setting hasn't brought back pop-up alerts. Rebooting had no effect.
System details:
- Windows 10 Enterprise
- Outlook Office 365 ProPlus, version 1903 (build 11425.20202 if this means anything)

Please confirm whether the new incoming messages are in the Inbox folder of the mailbox because new mail desktop only works for the default inbox.
You can refer to this thread to check if all the settings are correct:[Troubleshooting] New mail desktop alert not working
If issue persists, we can repair outlook data file to test the result.
Besides, for windows 10, there is an option called Quiet Hours in side tab. It will block all active alerts. If it is turned on, please turn off this option.
