Outlook 365 desktop email notification not working

Copper Contributor

Outlook 365 Desktop email notification suddenly stopped working for one of the Windows Server 2019 users. For other users, the notification of a new email in the form of a message and an envelope on the icon in the systray is working correctly.

- Notifications are enabled in the Outlook settings.

- Notifications are enabled in the Windows settings.

- There are no policies set in Outlook.

- Focus mode turned off.

- Registry entries correctly set to receive notifications.

What could be the reason for the sudden disappearance of new e-mail notifications in Outlook and how can I fix it? This behavior only occurs for one user ...

Press the Win + R keys
Open "RoamCache" folder and delete all the files.

I tried and unfortunately it didn't work.
Hey @Terry_Lazer Thank you for your response.
i tried your suggestions and unfortunately the problem didn't fix :(

@Mskakun405 I was finally able to fix this same issue by removing the mail profile in Outlook and then re-adding it. Try that out, if you are still having the issue. 



Do you have a chance to login to another fresh workstation and test again to see whether the result the same?
