When Outlook receives a new message, it uses a default chime. This chime is handled in Windows, instead of Outlook, and is also used by the Mail app, the regular (non-Outlook) client that comes with Windows 10. The clock is enabled by default in Outlook, but you can turn it off or change it. to play something else. How to use.
Turn off the clock
If you do not want a hearing alert every time you receive a message (which may be especially affected if you use headphones) you can tell Outlook that you do not play a noise at all. Go to File> Options> Email and scroll down to the Message Arrival section. The setting you are looking for is "Play a sound".
Turn off and then click "OK". Outlook will no longer play a sound when a message arrives.

Change Chime to Something Other
If you still want a hearing alert but want nothing but the default sound, open Control Panel ( click Start and type "Control Panel") and then click the "Sound" option.
In the Sounds window that opens, switch to the "Sound" tab, scroll down a bit in the "Program events" box and select "New Mail Notification" option.
By default, Windows uses the built-in "Windows Notify Email.wav" audio file. Open the drop-down menu to select another installed audio, or click "Browse" to select your own audio file.
The sound must be a WAV file, so if you have another file type you want to use, you need to convert it (we are big Audacity or VLC fans for audio work, but use your tool). When done, click "OK" to finish saving your change and exit the Sound window. Restart Outlook and your new audio will be played when a message arrives.
