1) Open Lotus Notes.
2) Click "File," and then click "Preferences." (Mac users click "Lotus Notes," followed by "Preferences.")
3) Click the "+" icon next to "Mail," and click "Sending and Receving." Set the number of minutes that Lotus Notes "Check[es] for new mail" if you want to change the frequency with which the program checks for new email.
4) Click "Play a Sound" to set up the sound notifications. Click "Browse" to choose a sound that will play once a new email has been received. You can only choose files in the "C:\Windows\Media" (Windows\Sound\ on some operating systems) folder, and they must be in the WAV file format.
5) Click "Open" once you have chosen your selected sound and then click "OK" to save changes. Next time you receive an email, your new sound notification will play.
