Microsoft Teams, channels not giving popup notifications

After resent Microsoft Teams issues we have an issue regarding our users not receiving notifications from Teams.

When users post in a channel the channel only gets marked with bold letters.
No popup is appearing or any other indication in the activity bar that there has been a new post.

I have checked the notification settings and it seems like every channel is set to "notifications Off" for all users.

This has not been an issue before. So is this a change Microsoft has made or can i globally change the setting?

    Hello @Lasse Schmidt Schrader,

    Thank you for your message and for the detailed explanation. I understand how confusing this behavior can be, especially when notifications were working differently before.

    Regarding your question about whether this can be changed globally, at the moment I haven’t seen any official announcement indicating a recent change to this behavior. From my own testing environment, the notification settings are still functioning as expected.

    To help move this forward, you may ask the affected users to try adjusting their settings by going to Teams Settings > Notifications and activity, then scroll down to “Posts in all shown channels”. From there, they can try setting it to “Show in activity and banner” or “Show in activity” and also make sure to enable “Include replies”. This configuration applies more broadly across channels and may help restore more visible notifications.

    However, it would also be important to double check at the individual channel level as well. Each user can open a specific channel, click on the three dots, and adjust Channel notifications to “Show in Activity”. This ensures that notifications for that particular channel are not being limited or overridden.

    If after making these adjustments the users are still not receiving notifications as expected, I would recommend raising a support ticket through the Admin Center. This will allow the backend support team to take a closer look and perform a more detailed investigation on the service side.

    Thank you very much for your cooperation, and please feel free to keep me updated on the results.

    Best regards,

    This behavior is controlled by Teams notification settings, and there is no indication in the provided information that Microsoft has globally changed defaults for all tenants. What is visible is that channel notifications can be turned off per user and per channel, and that users (or policies/tools) can configure them so that only bolding appears without banners.

    Key points and what to check:

    1. Per‑user global notification settings
      Each user can control how channel activity appears:
      1. In Teams, select Settings and more (three dots in the top-right).
      2. Select Settings > Notifications and activity.
      3. Under Chats and channels / Channel notifications, choose how channel notifications are delivered (for example, Activity and banner instead of only Activity or Off).
      These settings determine whether users see pop‑up (banner) notifications or only bold channels/activity feed entries.
    2. Per‑channel notification settings (user‑side)
      For each channel, users can override the global setting:
      1. Hover over the channel name.
      2. Select More options > Channel notifications.
      3. Choose:
        • All new posts (and optionally Include replies)
        • Channel mentions
        • Delivery method: Banner and feed or Only show in feed, or Off.
      If channels are showing only bold text with no pop‑ups, they are likely configured as Only show in feed or Off for those users.
    3. Activity feed vs. banner behavior
      When channel notifications are set to Only show in feed, users see:
      • Bold channel names and entries in Activity,
      • But no desktop banner pop‑ups.
      To restore pop‑ups, users must change to Banner and feed either globally (Notifications and activity) or per channel.
    4. Admin/global control
      From the provided information, channel notification behavior is user‑configurable in the Teams client. There is no documented global “force banner notifications for all channels for all users” switch in these references. Admins can influence mobile notification behavior via Intune app protection/configuration policies (for example, turning Teams channel notifications on or off for mobile devices), but that is specifically for Teams mobile apps and lock‑screen/home‑screen notifications, not desktop banners.
    5. If many users changed at once
      If all users suddenly have channel notifications set to Off or to feed‑only, possible causes include:
      • A change in how users’ own Notifications and activity settings were configured (for example, a manual or scripted change, or users adjusting settings).
      • Mobile app protection/configuration policies affecting mobile notifications (if Intune is used), but this would not directly explain desktop banners.

    In practice, to restore pop‑up notifications:

    1. Instruct users to:
      • Go to Settings and more > Settings > Notifications and activity.
      • Under Chats and channels, ensure channel notifications are set to show in Activity and banner.
    2. For important channels, have users:
      • Hover over the channel > More options > Channel notifications.
      • Set All new posts (and Include replies, if needed) to Banner and feed.

    If centralized control is required for mobile notifications (for example, to ensure they are not suppressed or to mask content), configure the Org data notifications and Teams notification keys via Intune app protection and configuration policies.
