Fix Microsoft Teams Notifications Not Working on Windows 10

If Microsoft Teams notifications are not appearing on Windows 10, the problem usually lies in notification settings either within Teams itself, in Windows 10’s notification center, or in how Teams is running (e.g., in the background or minimized). This guide walks through every likely cause and the exact steps to fix them, from the simplest check to deeper system settings.

Why Teams Notifications Stop Working

Teams notifications can fail for several reasons, often interacting with each other. The most common are:

• Teams notification settings – notifications are muted, or specific channels/chats are set to “off.”
• Windows 10 notification settings – notifications for Teams are disabled, or Focus Assist (Do Not Disturb) is blocking them.
• Teams running in the background – when minimized to the system tray, Teams may not display notifications if background app permissions are restricted.
• Outdated Teams or Windows – bugs in older versions can break notification delivery.
• Corrupted Teams cache – a damaged cache can cause the app to behave erratically.
• Multiple accounts or profiles – sometimes notifications are tied to a different account than the one you’re using.

Check Teams Notification Settings First

Before touching system settings, verify Teams’ own notification preferences. In the Teams desktop app:

1. Click your profile picture at the top right, then select Settings.
2. Go to Notifications.
3. Review the toggles for Chat, Mentions, Reactions, and Channel messages. Ensure they are set to Banner and email or Banner, not “Off” or “Only in feed.”
4. Also check Show notifications when I’m inactive – if this is off, you won’t see banners when the app is in the background.

If you’re missing notifications from a specific channel, right-click that channel, select Notifications, and choose Custom to set what triggers alerts.

Check Windows 10 Notification Settings

Windows 10 has its own notification center that can block Teams. To check:

1. Open Settings (Win + I) > System > Notifications & actions.
2. Make sure Get notifications from apps and other senders is turned on.
3. Scroll down to find Microsoft Teams in the list of apps. Click it and ensure Notifications is enabled.
4. Also check the sub-options: Show notification banners and Show notifications in notification center should be on.

If Teams isn’t listed, it may be because the app hasn’t sent any notifications yet. Launch Teams, send yourself a test message, then check again.

Disable Focus Assist (Do Not Disturb)

Focus Assist (formerly Quiet Hours) suppresses notifications during certain times or when you’re doing specific tasks. To check:

1. Open Settings > System > Focus Assist.
2. If it’s set to Priority only or Alarms only, notifications from Teams may be blocked unless Teams is in your priority list.
3. Click Customize your priority list and ensure Microsoft Teams is added under Apps.
4. If you don’t want any blocking, set Focus Assist to Off.

Also check the Automatic rules section – Focus Assist might be turning on automatically during presentations or when you’re using an app in full screen.

Allow Teams to Run in the Background

Teams needs to run in the background to receive notifications when you’re not actively using it. Windows 10 may restrict background apps to save battery. To allow it:

1. Open Settings > Privacy > Background apps.
2. Ensure Let apps run in the background is turned on.
3. Scroll down and make sure Microsoft Teams is set to On.

If you’re using a laptop, also check the battery saver settings. When battery saver is on, background notifications may be delayed or blocked. You can exclude Teams from battery saver by going to Settings > System > Battery > Battery saver settings and adding Teams to the Always allowed list.

Update Teams and Windows 10

Outdated software can have bugs that are already fixed in newer versions. To update Teams:

• Click your profile picture in Teams, then select Check for updates. Teams will download and install any available updates automatically.
• For Windows 10, go to Settings > Update & Security > Windows Update and click Check for updates. Install any pending updates and restart your PC.

After updating, restart Teams completely (right-click the Teams icon in the system tray and choose Quit, then reopen it).

Clear Teams Cache and Reinstall

If notifications still fail, a corrupted cache might be the culprit. Clearing it is safe and often resolves odd behavior:

1. Quit Teams completely (right-click the tray icon and select Quit).
2. Press Win + R, type %appdata%\Microsoft\Teams, and press Enter.
3. Delete the contents of the Cache, Code Cache, GPUCache, and blob_storage folders (if they exist).
4. Restart Teams. It will recreate the cache.

If that doesn’t help, uninstall Teams and reinstall it from the official Microsoft website. Make sure to back up any important chats (they’re stored in the cloud, so you won’t lose them).

Frequently Asked Questions

Why do I get Teams notifications on my phone but not on my PC?

This usually means the PC version is not running in the background or Windows is blocking notifications. Check the background app permission and notification settings as described above. Also ensure you’re signed in to the same account on both devices.

Teams shows a red badge but no banner notification – why?

This indicates that Teams is receiving the message but Windows is not showing the banner. Check Focus Assist and the notification settings for Teams in Windows. Also, in Teams settings, make sure the notification type is set to Banner rather than Only in feed.

Will notifications work if Teams is minimized to the system tray?

Yes, they should, as long as Teams is allowed to run in the background and Windows notification settings are correct. If you close Teams to the tray, it continues to run and can show banners. If you fully quit Teams, you won’t get any notifications.

Do I need to keep Teams open to get notifications?

Yes, Teams must be running (even in the background) to receive notifications. If you close the app completely, you won’t get alerts. You can set Teams to start with Windows by going to Settings > General and enabling Auto-start application.

Why are my notifications delayed by a few minutes?

Delays can happen when the Teams app is not running in the foreground and Windows throttles background activity to save battery. Check battery saver settings and ensure Teams is allowed to run in the background. Also, check your internet connection – a weak connection can delay message delivery.

Can I get notifications for all channels or only for mentions?

Yes, you can customize this. In Teams, go to Settings > Notifications and adjust the Channel messages option. You can choose to be notified for all new messages, only mentions, or nothing. For specific channels, right-click the channel and select Notifications to override the default.
