Fix Microsoft Teams Notifications Not Working on Mac

If you’re on a Mac and Microsoft Teams notifications have stopped appearing, the fix usually involves checking a combination of macOS notification settings, Teams’ in-app notification preferences, and the app’s focus status. This guide walks through the most common causes and the exact steps to resolve them, from simple toggles to more advanced troubleshooting.

Why Teams Notifications Fail on macOS

Teams on Mac depends on two separate systems working together: the macOS notification center (which controls how alerts appear on your screen) and Teams’ own internal settings (which decide what events trigger a notification). A problem in either layer can silence alerts. Common culprits include:

• macOS Focus modes (Do Not Disturb) blocking notifications
• Teams being set to “Off” in System Settings > Notifications
• In-app notification style set to “Only show in feed” or “Off”
• Teams running in the background with “Presence” set to a status that suppresses alerts
• Outdated Teams app or macOS version with known notification bugs

Step 1: Check macOS Notification Permissions

macOS controls which apps can show notifications. If Teams was denied permission during setup, or if a system update reset permissions, you won’t see alerts.

1. Open System Settings (Apple menu > System Settings).
2. Click Notifications in the sidebar.
3. Scroll to find Microsoft Teams in the app list.
4. Ensure the toggle next to “Allow Notifications” is on (green).
5. Set the alert style to Alerts or Banners (not “None”).
6. Make sure “Badge App Icon” and “Sound” are enabled if you want those.

If Teams isn’t listed, it may not have requested permission. Open Teams, go to Teams > Settings, and trigger a notification (like a test message) to prompt the system dialog. Click “Allow” when it appears.

Step 2: Verify Teams In-App Notification Settings

Even if macOS allows notifications, Teams has its own settings that can override them. Click your profile picture in Teams, then select Settings > Notifications. Here you’ll see categories like “Messages,” “Mentions,” and “Reactions.” For each, choose the style:

• Banner and email – shows a banner on your Mac
• Banner – shows a banner only
• Only show in feed – no banner, just the activity feed icon
• Off – no notification at all

Make sure the categories you care about (e.g., “Direct messages,” “Mentions”) are set to “Banner” or “Banner and email.” Also check that “Suggested replies” or “Quiet hours” aren’t enabled, as they can suppress alerts.

Step 3: Turn Off Focus Modes and Do Not Disturb

macOS Focus modes (Do Not Disturb, Sleep, Personal, Work) can block Teams notifications entirely. If you’ve scheduled a Focus or enabled it manually, alerts won’t appear.

1. Open Control Center (the icon in the menu bar).
2. Click Focus and check if any mode is active (highlighted).
3. If active, click it to turn it off, or click the “X” next to the mode name.
4. To allow Teams during a Focus, go to System Settings > Focus > select the mode > “Allowed Apps” and add Teams.

Step 4: Check Teams Status and Presence

Teams automatically suppresses notifications when your status is “Do not disturb” or “In a call.” If you’re in a meeting or on a call, alerts may be delayed or hidden. Check your status in the Teams window:

• Click your profile picture and ensure you’re not set to “Do not disturb.”
• If you’re in a call, notifications are muted by design; they’ll resume after the call ends.
• You can override this by going to Settings > Notifications and enabling “Show notifications during calls” (if available in your version).

Step 5: Restart Teams and Reset Its Cache

A corrupted cache can cause notification failures. Restarting Teams often clears temporary glitches. If that doesn’t work, reset the cache:

1. Quit Teams completely (Cmd+Q).
2. Open Finder and press Cmd+Shift+G, then type ~/Library/Application Support/Microsoft/Teams.
3. Delete the contents of the following folders (but not the folders themselves): Cache, Code Cache, GPUCache, Service Worker, and blob_storage.
4. Restart Teams and sign in again.

This forces Teams to rebuild its local data and often resolves notification issues.

Step 6: Update Teams and macOS

Microsoft regularly releases updates that fix bugs, including notification issues. Check for updates by clicking your profile picture in Teams and selecting Check for updates. If you’re using the Mac App Store version, open the App Store and click “Updates.” Also ensure macOS is up to date via System Settings > General > Software Update.

Step 7: Use the Web Version as a Temporary Workaround

If desktop notifications still fail, try Teams in a browser (e.g., Safari or Chrome). Go to teams.microsoft.com, sign in, and enable notifications in your browser settings. This can restore alerts while you troubleshoot the desktop app. Note that browser notifications require the tab to be open (or backgrounded with permission).

Frequently Asked Questions

Why did my Teams notifications stop working after a macOS update?
macOS updates can reset notification permissions or change Focus settings. Re-check System Settings > Notifications for Teams and re-enable Focus exceptions.

Can I get notifications when Teams is closed?
Yes, but only if Teams is running in the background (not quit). If you quit Teams completely, you won’t get alerts. Keep it open in the Dock with the window closed.

Why do I get notifications on my phone but not on my Mac?
This usually means macOS permissions are off, or Teams’ in-app settings are set to “Only show in feed.” Check both layers as described above.

How do I enable sound for Teams notifications on Mac?
In System Settings > Notifications > Teams, enable “Sound.” Also in Teams Settings > Notifications, ensure “Play sound” is on for the relevant categories.

Does using a VPN affect Teams notifications?
Yes, a VPN can block the push service that Teams uses. Try disconnecting the VPN and sending a test message.

What if none of these steps work?
Try uninstalling and reinstalling Teams, or contact your IT admin. They can check if your organization has policies that disable notifications.
