how do i stop new email notifications in the new outlook on windows 11

Since Outlook’s main notification setting is already off, disable notifications for each Outlook account and then turn off the Outlook (new) sender in Windows 11.

1. Check each account in new Outlook

This applies if more than one account is configured:

1. Open new Outlook.
2. Select Settings (gear) → General → Notifications.
3. Expand Mail or select Expand to display account-specific settings.
4. Turn off new-email notifications and sounds for every listed account.

New Outlook supports separate notification settings for individual accounts, so an enabled account can continue generating alerts even when another account is disabled.^1^

2. Disable the Windows app-level sender

This is separate from Outlook’s own settings and avoids changing the global Windows notification switch:

1. Open Start → Settings → System → Notifications.
2. Under Notifications from apps and other senders, find Outlook (new) or Outlook.
3. Turn that app’s switch Off.
4. If multiple Outlook entries appear, turn off the entry that produces the notification—or turn off both if no Outlook notifications are wanted.

Alternatively, when an Outlook alert appears, select its … menu and choose Turn off all notifications. Windows supports disabling an individual app without disabling notifications globally.^2^

3. Clear old notifications

Press Windows key + N, then:

• Clear the existing Outlook notifications, or
• Select Clear all.

This removes alerts already stored in Notification Center; changing the setting prevents new ones but does not necessarily remove existing entries.

If alerts still arrive

Completely close new Outlook through Task Manager:

1. Right-click Start → Task Manager.
2. Select Microsoft Outlook → End task.
3. Reopen Outlook and send a test email.

If the notification still appears, note the app name shown on the banner. If it names a browser, Teams, classic Outlook, or another mail application rather than Outlook (new), disable that named sender under Settings → System → Notifications instead.
