Missing a Teams notification can mean a delayed response to a client, a missed meeting reminder, or being the last to know about an urgent message. When Teams notifications stop working — no pop-ups, no sounds, no badge counts — the causes range from a muted setting you forgot about to a Windows Focus Assist override that is silencing everything. This guide walks through every fix in order, starting with the most common causes and working through to a full reinstall if nothing else resolves it.
Why Teams Notifications Stop Working
Before diving into fixes, it helps to understand what is most likely causing the silence. Teams notifications can be blocked at several different layers — inside Teams itself, inside Windows, or at the level of a specific channel or conversation. Common reasons include:
- Quiet hours or Do Not Disturb status is active inside Teams
- Windows Focus Assist (Windows 10) or Do Not Disturb (Windows 11) is blocking all notifications at the OS level
- Teams notifications are turned off in Windows notification settings
- The Teams app has its own notification settings that override what Windows is set to do
- You are currently in a meeting — Teams suppresses certain notifications during active calls to avoid distraction
- The specific channel or chat conversation has been individually muted
- Teams is running on the device but you are not signed in, so no notifications are being delivered to that session
Work through each of the fixes below in sequence. Most users find the problem within the first three steps.
Fix 1 — Check Your Teams Notification Settings
The first place to look is inside Teams itself. Click the three dots (…) next to your profile picture in the top-right corner, then select Settings and navigate to Notifications. This screen is divided into several sections — Chat, Meetings, People, and Other — and each one controls a different type of notification.
The most important things to check here are:
- Mentions — this should be set to Banner and email or at minimum Banner only. If it is set to Only show in feed or Off, you will never see a pop-up when someone tags you
- Missed activity emails — useful as a backup, but not a replacement for live banners
- Quiet hours — if a quiet hours schedule has been configured, Teams will block notifications during those times even if everything else is correctly set. Scroll down to find the quiet hours section and disable it if you do not need it
Once you have reviewed all sections and made any changes, send yourself a test message from another account or ask a colleague to ping you to see if banners appear.
Fix 2 — Check Your Teams Status Is Not Do Not Disturb
If your status is set to Do Not Disturb, Teams will suppress almost all incoming notifications by default — regardless of what your notification settings say. This is one of the most common causes of a sudden notification blackout, especially because Do Not Disturb can be triggered accidentally from the status menu during a meeting and left in place long after the call ends.
To check your status, click your profile picture in the top-right corner of Teams. The status is displayed directly beneath your name. If it shows Do Not Disturb, click it and change it to Available. Also check whether a manual status duration has been set — for example, Do Not Disturb for 2 hours — because this will keep you in DND even if you try to change it without clearing the duration first.
If your status appears correct but still does not seem to reflect what you expect, read our full guide on Microsoft Teams status not updating for a deeper set of fixes.
Fix 3 — Check Windows Notification Settings for Teams
Even if Teams is configured correctly, Windows can override notification delivery at the system level. Open Settings, go to System, and click Notifications (Windows 11) or Notifications and actions (Windows 10). Scroll down to the list of apps and find Microsoft Teams.
Make sure the toggle for Teams notifications is set to On. Click through into the Teams entry and check that both Banners and Sounds are enabled. If either of these is turned off at the Windows level, no amount of adjusting settings inside Teams will bring back pop-up notifications or alert sounds.
Note that Windows may list two separate Teams entries if you have both the work or school version and the personal version installed, or if you have the new Teams (Teams 2.0) alongside the classic client. Check both entries and make sure notifications are enabled for the version you actually use day to day.
Fix 4 — Check Focus Assist or Do Not Disturb in Windows
Windows has its own notification suppression system that operates independently of both Teams and app-level settings. On Windows 10 this is called Focus Assist; on Windows 11 it was renamed to Do Not Disturb. When either of these is active, all notifications — including Teams — may be silenced completely.
On Windows 10, go to Settings > System > Focus Assist and make sure it is set to Off. If you need Focus Assist for other purposes, keep it enabled but add Microsoft Teams to the Priority only list so Teams notifications are always allowed through.
On Windows 11, go to Settings > System > Notifications and check whether Do Not Disturb is toggled on or scheduled. If a schedule is active — for example, outside of working hours — Teams will be silenced during those windows. You can add Teams to the Priority notifications list so it is always allowed through even when Do Not Disturb is on for other apps.
One thing worth knowing is that Focus Assist and Do Not Disturb can activate automatically without you switching them on manually. Common triggers include running an app in full-screen mode, mirroring your display for a presentation, or crossing a scheduled time boundary. If you use Teams during presentations, check whether full-screen mode is automatically enabling Focus Assist and suppressing your notifications.
Fix 5 — Check If the Channel or Chat Is Muted
In Teams, individual channels and one-on-one or group chat conversations can be muted independently. When a channel or conversation is muted, messages posted there will never trigger a notification banner or sound, even if your global notification settings are configured correctly. This is easy to overlook because the muted state is not visually prominent.
To check whether a specific channel or chat is muted, right-click on its name in the left-hand sidebar. If the context menu shows an Unmute option, that conversation is currently muted — click it to restore notifications. If it shows Mute, it is currently active and notifications should be working normally.
You can also see all of your muted channels in one place by going to Settings > Notifications and scrolling to the bottom of the page where a muted channels list is displayed. From there you can unmute in bulk without having to track down each channel individually.
One useful workaround: even in a muted channel, a direct @mention of your name will still trigger a notification. If you need to follow a busy channel without constant alerts, muting it and relying on @mentions for the important stuff is a legitimate strategy.

Fix 6 — Clear the Teams Cache
A corrupt or oversized Teams cache can cause a range of unpredictable behaviour, including notifications that appear inconsistently or stop working altogether. Clearing the cache forces Teams to rebuild its local data from scratch and resolves many issues that cannot be fixed by changing settings alone.
- Right-click the Teams icon in the system tray (bottom-right corner of the taskbar) and select Quit to fully close the app — not just minimise it
- Press Windows + R to open the Run dialog and type
%appdata%\Microsoft\Teams, then press Enter - Delete the following folders: Cache, blob_storage, databases, GPUCache, IndexedDB, Local Storage, and tmp
- Reopen Microsoft Teams and sign back in if prompted
Teams will rebuild these folders automatically as it runs. Notification delivery often resumes immediately after this step. Your conversations, files, and channels are stored on Microsoft’s servers and will not be affected — only the local cache is cleared.
Fix 7 — Sign Out and Back In, or Reinstall Teams
If you have worked through all of the above and notifications are still not appearing, the problem may be deeper than a settings issue. Signing out of Teams and back in forces a full resync of your account configuration — including notification preferences — with Microsoft’s servers. To sign out, click the three dots next to your profile picture and select Sign out. Once signed in again, check whether notifications have resumed.
If signing out and back in does not resolve it, a clean reinstall is the most thorough option. Go to Settings > Apps in Windows, find Microsoft Teams in the list, and uninstall it. Then download and install the latest version from the Microsoft website. A fresh install replaces any files that may have been corrupted during a failed update, which can silently break notification delivery hooks without producing any visible error.

Frequently Asked Questions
Why do I get Teams notifications on my phone but not my desktop?
Teams uses a prioritisation system for multi-device setups. If you are actively using Teams on your mobile — even if you are just scrolling — the desktop client may be deprioritised and not receive the same notification. More commonly, the desktop notification settings are correct on mobile but misconfigured on Windows. Go through Fix 3 and Fix 4 above to check the Windows-level settings, as the phone app bypasses these entirely.
How do I get notified when someone posts in a specific channel?
By default, Teams only notifies you for direct replies to your posts and @mentions in channels. To be notified of all new posts in a specific channel, click the three dots next to the channel name, select Channel notifications, and change the setting from Default to All new posts. Be selective with this — enabling it across many channels will quickly become overwhelming.
Can I get notifications for keywords mentioned in channels?
Yes. Teams supports keyword notifications that trigger an alert whenever specific words appear in a channel message, even if you are not directly mentioned. Go to Settings > Notifications > Other and scroll down to the Keywords section. Enter any words or phrases you want to be alerted about — your company name, a project code, or a product name, for example.
Why do Teams notification sounds work sometimes but not always?
Inconsistent notification sounds are usually caused by Windows audio settings changing — for example, a different audio output being selected, or a second monitor or docking station switching the default audio device. Teams plays its notification sounds through whatever the current default audio output is at the time. If you unplug headphones and Teams switches to speakers (or vice versa) without you noticing, sounds may appear to stop working. Check Settings > System > Sound in Windows to confirm the correct output device is selected, and make sure the Teams notification volume has not been reduced in the Windows volume mixer.
