Configuring preferences and options in Outlook.com
Hi LMFPeach and FlipmodeMF,
Thank you for getting back to us. Since the option to turn the sounds off on Outlook.com app does not work, then there is a possibility that the Outlook.com app itself is causing this issue. It might be that the Outlook.com app is faulty.
Now, we recommend that you uninstall the Outlook.com app and download the latest version of it from the Play store. Once done, we recommend that you turn the email notification sound off by following the steps below:
1. Open the Outlook.com app on your mobile device.
2. Tap on the Menu option.
3. Tap on Settings.
4. Choose General.
5. Choose notifications.
6. Click on email notifications and then make sure that the box is unchecked.
7. Tap on Audio Notification.
8. When you get into your notification, choose the "silent" button.
Let us know how things turn out. Feel free to post back if you have further questions.
Regards,
Johayber T.
