You have opened the new Outlook for Windows and noticed that new email notifications no longer play a sound. The notification banner still appears, but the audio alert that you relied on for urgent messages is gone. This typically happens because the default notification profile in the new Outlook disables sound alerts, or because a specific account has its notification sound turned off separately. This article explains why the sound is missing and provides the exact steps to re-enable notification sounds for individual email accounts.
Key Takeaways: Re-Enabling Per-Account Notification Sounds in New Outlook
- Settings > General > Notifications > Play a sound: Toggle this master switch to On to allow any account to play a sound.
- Settings > Mail > Accounts > [Account Name] > Notifications: Enable the per-account sound toggle that overrides the global setting.
- Settings > Calendar > Notifications: Check this if calendar reminder sounds are also missing; calendar notifications have their own sound toggle.
Why New Outlook Notification Sounds Are Disabled by Default
The new Outlook for Windows uses a different notification engine than the classic version. When Microsoft designed the new Outlook, they set the default notification profile to show banners without sound. This change was made to reduce interruptions during meetings or focused work sessions. The notification system also treats each email account independently. If you add a second account, that account inherits the no-sound default unless you manually change it.
Another reason the sound may be disabled is that the Windows system sound for new mail notifications is turned off. The new Outlook relies on the Windows notification platform to play the audio file. If Windows itself has the new mail notification sound set to None, Outlook cannot override it. The fix requires checking both the Outlook per-account setting and the Windows sound scheme.
Steps to Re-Enable Notification Sound Per Account in New Outlook
Follow these steps to turn on notification sounds for one account without affecting other accounts. You must repeat the per-account steps for each account that should play a sound.
- Open Outlook Settings
In the new Outlook, click the gear icon at the top-right corner of the window. This opens the Settings pane. - Navigate to Notifications
In the Settings pane, click General on the left menu, then click Notifications. This page controls how Outlook alerts you about new items. - Enable the Master Sound Toggle
Find the switch labeled Play a sound and set it to On. If this is Off, no account can play notification sounds. Leave this pane open. - Go to Mail Account Settings
Click Mail in the left menu of the Settings pane. Then click Accounts to see the list of email accounts configured in Outlook. - Select the Account to Configure
Click the name of the account for which you want to enable notification sounds. The account settings page opens. - Open Account Notifications
In the account settings page, click Notifications. This section contains toggles for the selected account only. - Turn On Sound for This Account
Set the Play a sound switch to On. You can also choose whether to show a banner or show an icon in the taskbar. Close the Settings pane when done.
Repeat steps 4 through 7 for each additional account. The master toggle in General > Notifications must stay On for the per-account settings to work.
If Outlook Still Does Not Play Notification Sounds
Windows Sound Scheme Is Set to No Sounds
Open the Windows sound control panel. Press Windows key + R, type mmsys.cpl, and press Enter. Click the Sounds tab. In the Program Events list, scroll down to New Mail Notification. Click it, then use the Sounds dropdown to select a .wav file such as Windows Notify Email. Click Apply and OK. This restores the system sound that Outlook triggers.
Focus Assist or Quiet Hours Are Active
Windows 10 and Windows 11 have a Focus Assist feature that silences all notification sounds during certain hours or when you are duplicating your display. Press Windows key + A to open Action Center. If Focus Assist is on, click it to cycle to Off. To configure automatic rules, go to Settings > System > Focus Assist and turn off automatic rules that may suppress sounds.
Outlook Notification Sound Is Muted in Volume Mixer
Right-click the speaker icon in the taskbar and select Open Volume Mixer. Look for the Outlook entry. If its volume slider is at the bottom or muted, drag it to at least 50 percent. The Volume Mixer applies per-app volume settings that override the system sound level.
New Outlook Notification Settings: Global vs Per-Account Comparison
| Item | Global Setting (General > Notifications) | Per-Account Setting (Mail > Account > Notifications) |
|---|---|---|
| Scope | Applies to all accounts in the new Outlook | Applies only to the selected email account |
| Sound toggle | Master On/Off for all sounds | On/Off for that account only |
| Banner toggle | Yes, controls banner visibility for all accounts | Yes, controls banner visibility for that account |
| Taskbar icon toggle | No, not available at global level | Yes, can show an envelope icon in the taskbar |
| Default state | Sound Off, Banner On | Sound Off, Banner On |
You can now re-enable notification sounds for each email account individually in the new Outlook. Start with the master sound toggle in General > Notifications, then configure each account in Mail > Accounts. If sounds still do not play, check the Windows sound scheme and Focus Assist settings. For quick verification, send a test email from another account to confirm the audio alert works.
