How to Fix Teams Notifications Not Showing Up? 10 Fixes 2026

Microsoft Teams notifications not showing up means your chats, channel messages, mentions, or calls are arriving silently inside the app without a desktop banner, sound, or mobile push. We refreshed this guide for 2026 after a fresh round of testing across Windows 11, macOS, iPhone, Android, and the browser because the New Teams rollout keeps producing the same symptom users keep reporting on the Microsoft Q&A forums.

Last updated: September 2026. Tested on Teams desktop version 24215+, New Teams, and the web app at teams.cloud.microsoft.

Before you scroll through ten settings menus, here are the most common culprits we have seen knock Teams alerts out:

• Focus Assist or Do Not Disturb is turned on in Windows.
• Your presence status is set to Do Not Disturb, Busy, or Appear Offline inside Teams.
• The Windows notification permission for Teams has been toggled off.
• You enabled Block notifications when active on other devices on your phone.
• A stale Teams cache is preventing the notification subsystem from loading.
• Battery Saver on Windows, iOS, or Android is suppressing background alerts.
• Your work or school IT admin has applied an organisational notification policy.

Fixes at a Glance: How to Fix Teams Notifications Not Showing Up

If you only have a minute, work through this numbered list in order. Every fix links to a full step-by-step section further down.

1. Open Teams and set your status to Available.
2. Disable Focus Assist / Do Not Disturb in Windows.
3. Allow Teams in Windows Settings > System > Notifications.
4. Turn on the right rules under Teams Settings > Notifications and activity.
5. Override per-channel rules for any channel you actually want alerts from.
6. Turn off Battery Saver and any background-app restrictions.
7. Clear the Microsoft Teams cache from %appdata%MicrosoftTeams.
8. Sign out, restart Teams, then sign back in.
9. Repair or reset the Teams app from Windows Settings > Apps.
10. On managed accounts, ask IT to check the Teams notification policy.

Allow Notifications in Teams App Settings

The most common reason Microsoft Teams notifications are not showing up is that the in-app notification rules were never turned on. Teams lets you mute almost every surface by default.

1. Click the three dots Settings and more (…) menu next to your profile picture.
2. Choose Settings > Notifications and activity.
3. Under Banner and feed, make sure notifications are set to Banner and feed or Only show in feed for Chat, Channels, Meetings, and Mentions.
4. Turn on Also notify for Reactions, Replies, and Likes if you want those.
5. Switch Play sound for notifications to On.
6. Restart Teams.

Why this helps: Banner and feed controls both the pop-up corner banner and the Activity feed entry. If only one of the two is on, you can see a notification in the feed but no banner will appear on the desktop.

Disable Focus Assist / Do Not Disturb in Windows

Focus Assist is Windows’ system-wide Do Not Disturb mode. When it is on, Teams banners are silently swallowed even if every Teams setting is correct.

1. Click the date and time in the bottom-right corner of the taskbar.
2. Toggle off Focus Assist (it shows as a moon icon). If it says Off, you are good.
3. If a priority list is set, click Focus Assist > Priority only and add Microsoft Teams under apps.
4. Open Settings > System > Focus and confirm Do Not Disturb is Off and the schedule is empty.

Why this helps: Focus Assist lives above Teams in the Windows notification stack. Teams does not get a chance to display its banner if the OS already filtered it out.

Check Windows Notification Settings for Teams

Windows 10 and 11 both have a per-app notification switch. If someone (or a privacy tool) turned it off, Teams stops showing banners entirely.

1. Open Settings > System > Notifications.
2. Scroll to Microsoft Teams (or New Teams / Teams classic, depending on which build you run).
3. Toggle Notifications to On.
4. Make sure Show notification banners and Play a sound when a notification arrives are both checked.
5. Under Priority of notifications in the notification center, set Teams to Normal or higher.

Why this helps: The Teams in-app switch is independent of the Windows switch. Both must be on. Reviewers on r/MicrosoftTeams consistently report that toggling the Windows switch is the one fix that finally worked.

Reset Your Presence Status to Available

Teams suppresses banner notifications when your status is set to Do Not Disturb, Busy, or Appear offline. You can set status automatically from a meeting, calendar block, or focus session without noticing.

1. Click your profile picture in the top-right corner of Teams.
2. Set your status to Available.
3. Open Settings > Notifications and activity and confirm the status expiry has not been set to “until I change it.”
4. If you use Viva Insights, turn off Protect time and Quiet time, which also force Do Not Disturb.

Why this helps: Even when notification rules are fully on, Teams will not pop a banner if your own status is silencing it. This is the silent cause behind most “settings correct, still no alerts” complaints on Microsoft Q&A.

Enable Channel-Specific Notifications

Each Teams channel has its own notification override. The default is usually Channel default, but if anyone clicks the bell icon to mute it, every future message is silenced for that channel.

1. Open the channel you want alerts from.
2. Click the bell icon in the top-right of the channel header.
3. Choose All new posts, or pick Custom and select @mentions and replies only.
4. Repeat for any other channel where you want alerts.

Why this helps: Channel-level rules override the global Teams rule. Many users discover one accidentally muted channel is the only one they cared about.

Clear the Microsoft Teams Cache

A corrupted cache file in the Teams AppData folder is one of the top three reported causes for “Teams notifications suddenly stopped working after an update.”

1. Quit Microsoft Teams fully (right-click the system tray icon and choose Quit).
2. Press Win + R, type %appdata%MicrosoftTeams, and press Enter.
3. Select and delete every folder inside, but not the parent Teams folder itself. The folders to remove are Cache, blob_storage, databases, GPUCache, IndexedDB, Local Storage, and tmp.
4. Open Application Data > Microsoft > Teams the same way (Roaming) and delete the contents of Cache there too.
5. Relaunch Teams and sign back in.

Why this helps: Teams recreates a clean notification pipeline on next launch. The cache folders are only data, so deleting them forces a rebuild without losing your chats or files.

Sign Out, Restart, Repair or Reset Teams

When the cache step is not enough, a deeper reset is. The order matters: sign out, fully quit, then either Repair or Reset.

1. In Teams, click your profile picture and choose Sign out.
2. Right-click the Teams icon in the system tray and choose Quit.
3. Open Settings > Apps > Installed apps on Windows.
4. Find Microsoft Teams, click the three dots, and choose Repair. Wait for it to finish.
5. If banners still do not show after a restart, go back and choose Reset instead.

Why this helps: Repair re-registers the app without touching data. Reset is the equivalent of uninstalling and reinstalling while keeping your account signed in. Either can fix a permission that got knocked out by an update.

Turn Off Battery Saver and Background App Restrictions

Battery Saver on Windows, Low Power Mode on iPhone, and battery optimisation on Android all kill the background processes that deliver Teams notifications.

Windows

1. Open Settings > System > Power > Battery.
2. Turn Battery saver off.
3. Scroll to Battery saver is on at 20% by default and raise the threshold to 100%, or turn the automatic toggle off.

iPhone / iPad

1. Open Settings > Battery and turn off Low Power Mode.
2. Open Settings > Notifications > Teams and confirm Allow notifications is on.

Android

1. Open Settings > Apps > Teams > Battery.
2. Set Battery optimisation to Unrestricted.
3. Toggle Allow background activity on.

Why this helps: Without unrestricted background activity, the OS literally freezes the Teams process when the screen is off, so the push server cannot wake the app up to display a banner.

Update Teams and Windows

Microsoft ships Teams through its own update channel and Windows through a separate one. If either falls behind, notifications can break silently.

1. Click the three dots Settings and more menu and choose Check for updates.
2. Install anything pending, then restart Teams.
3. Open Settings > Windows Update on Windows, or System Settings > Software Update on macOS, and install pending updates.
4. Restart your computer after both updates finish.

Why this helps: Recent Teams updates have included notification regressions, and Microsoft has rolled fixes in fast follow-up builds. An out-of-date Teams is the most likely cause if everything was working last week.

The New Teams vs Classic Teams Regression (2026)

If your notifications stopped working after a Microsoft 365 update in 2026, you are likely on the New Teams build. Several users on r/MicrosoftTeams have reported that switching back to Classic Teams restored banners immediately.

1. Click the three dots Settings and more menu.
2. Look for a toggle labelled Use the new Teams. Turn it off to fall back to Classic Teams.
3. If the toggle is missing, your admin has locked the new client. Use the Classic Teams shortcut on the desktop until Microsoft ships the next update.

Why this helps: The New Teams rollout has shipped several notification regressions through 2026. Until your build is up to date, Classic Teams is a working fallback for many users.

macOS Notification Settings

macOS treats notifications as a per-app permission, separate from anything inside Teams. If the toggle is off at the OS level, no in-app setting can recover it.

1. Open System Settings > Notifications > Microsoft Teams.
2. Turn on Allow notifications.
3. Choose Banners as the alert style.
4. Check Show notifications on lock screen and Show in notification center.
5. Under Focus in System Settings, make sure Teams is not in a blocked apps list.

Why this helps: macOS Focus modes block notifications silently. Even if Teams settings are perfect, an active Focus filter will mute every banner.

iPhone / iOS Notification Settings

On iPhone, the most common cause we see in forums is the silent Block notifications when active on other devices toggle combined with the Teams app running on a desktop. iOS assumes you are already looking at Teams and stops pushing alerts.

1. Open Settings > Notifications > Teams.
2. Turn on Allow notifications, Banners, Sounds, and Badges.
3. Under Lock Screen, Notification Center, and Banners, all three should be checked.
4. Open the Teams mobile app and go to Settings > Notifications.
5. Turn off Block notifications when active on other devices.

Why this helps: That mobile toggle is a hidden foot-gun. With it on, your phone sees the desktop app is active and decides not to deliver push notifications for chat, channels, or mentions.

Android Notification Settings

Android manufacturers layer battery optimisation on top of the OS, which is why the same Teams build that works on iOS may stay silent on Android.

1. Open Settings > Apps > Teams.
2. Tap Notifications and make sure all categories are enabled.
3. Tap Battery and choose Unrestricted.
4. On Samsung phones, also open Settings > Battery > Background usage limits and remove Teams from Sleeping apps and Deep sleeping apps.
5. On Xiaomi or Oppo phones, also set Teams to Autostart in the security center.

Why this helps: Without unrestricted battery and autostart, Android freezes Teams within minutes of the screen turning off. Push notifications never arrive because the process is suspended.

Browser Notifications for Teams Web

Teams at teams.cloud.microsoft runs as a Progressive Web App. If you have never accepted the browser’s permission prompt, no banners will appear.

1. Open Teams at teams.cloud.microsoft in Chrome, Edge, or Firefox.
2. Click the padlock or tune icon next to the URL bar.
3. Under Permissions, set Notifications to Allow.
4. Sign out and back in to refresh the connection.
5. In Teams Settings > Notifications and activity, confirm Banner and feed is on.

Why this helps: Other Microsoft 365 apps like Outlook already had permission granted, so users assume Teams has it too. The browser prompt must be accepted independently for each site.

Advanced Fix: Re-Register Windows Push Notifications

If nothing else has worked, the Windows Push Notifications platform itself may need re-registration. This is a power-user fix and only takes a minute.

1. Right-click the Start button and choose Terminal (Admin).
2. Run the following PowerShell command:
   Get-AppxPackage -AllUsers Microsoft.Windows.ShellExperienceHost | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}
3. Restart your computer.
4. Test Teams notifications again.

Why this helps: ShellExperienceHost is the Windows process that delivers toast banners. Re-registering it restores the link between Teams and the Windows notification center, which fixes banners that have been silent for weeks.

Diagnostic: Send Yourself a Test Notification

Before you give up, run one quick diagnostic that tells you whether the issue is on your device, your account, or Microsoft itself.

1. Sign in to Teams from a second account (a friend’s, or a personal account).
2. Send a chat message to your main account.
3. If the banner shows up on your main device, the problem is in your own account settings, not in Teams.
4. If the banner does not show up, check the Microsoft 365 Service Health dashboard for any active notification outage.

Work and School Accounts: Check Your IT Admin Policy

What to do:

• Ask your IT admin to check the Teams notification policy in the Microsoft Teams admin center.
• Confirm whether a preset policy is overriding your custom policy.
• For BYOD devices, ask whether the policy allows user override.

When Nothing Works: Reinstall Teams

If every step above has failed and your account is not admin-managed, a clean reinstall is the last resort. We only recommend it after the steps above, because it is heavier than the cache or repair approach.

1. Open Settings > Apps > Installed apps.
2. Find Microsoft Teams, click the three dots, and choose Uninstall.
3. Download a fresh copy from www.microsoft.com/en-us/microsoft-teams/download.
4. Sign in with the same account.
5. Re-enable your notifications once Teams opens.

Why this helps: A reinstall replaces every system-level file, including the Windows Push Notification registration and the toast XML handler. This is the nuclear option that fixes a corrupt install that has survived every earlier repair.

Frequently Asked Questions

Wrapping Up: How to Fix Teams Notifications Not Showing Up

If you remember nothing else from this guide on how to fix Teams notifications not showing up, remember the order: set status to Available, disable Focus Assist, allow Teams in Windows notifications, and clear the cache. Those four steps resolve the problem for the majority of users on r/MicrosoftTeams and the Microsoft Q&A forum in our 2026 testing. If you are on a managed work or school account, the answer usually sits with your IT admin and a Teams notification policy, not with your own settings.
