we stopped receiving notifications from teams when comments are made on tasks

Hi @MUNEER | OMALC, 

I hope you are doing well.  

Thank you for reaching out regarding the issue of not receiving notifications when comments are added to Planner tasks in Teams. 

After reviewing your scenario, I would like to clarify that this behavior is expected following a recent update to Microsoft Planner, which was rolled out around early 2026. 

Specifically, Microsoft has introduced a new experience called Task chat, which replaces the previous comment system in Planner tasks. As a result of this update: 

• Notifications are no longer sent automatically for every comment 
• Instead, users will only receive notifications when they are explicitly @mentioned in a task conversation 

According to Microsoft’s official documentation: Comment on tasks in Microsoft Planner 

This indicates that notifications now depend on @mentions, representing a clear shift from the previous behavior, where comments could trigger broader notifications to task participants or the group.  

Furthermore, this change was intentionally introduced to reduce excessive notification noise and provide users with more control over when they are alerted. Consequently, the system now relies on @mentions to ensure that only relevant users receive notifications.  

To ensure that team members receive notifications, I recommend the following: 

• Use @mentions in task chat (e.g., @John) whenever attention or action is required 
• Communicate this update to your team to align expectations and avoid missed updates 

I fully understand that this change may impact existing workflows, especially for teams that relied on automatic notifications. Therefore, I encourage you to share your feedback directly with the Microsoft product team, particularly regarding: 

• The need for more flexible notification options 
• The ability to re-enable broader comment notifications

This was informative, thank you. Will Task Chats delete the way typical chats delete after 6 months? I understand the intention of refining the email clutter, but smaller teams were benefitting from the broad communication. It would be ideal to have a Chat option and Comment option to appease all end users and not just larger teams using the workflow.

Notifications for comments on Planner/Tasks in Teams are controlled partly in Planner and partly in Teams. After an update, these settings or app behaviors can change even if they appear correct.

To restore notifications for task comments:

1. Verify Planner/Tasks notification settings
   1. In the Planner web experience (or Tasks in Teams, then select Go to website), open the plan.
   2. Select the Settings button near the top right, then select Notifications.
   3. Ensure the options such as:
      • Someone assigns a task to me
      • A task assigned to me is late, due today, or due in the next 7 days are enabled.
   4. Select Save.
2. Check group email/notification behavior
   1. In the same plan, select the 3 dots (…) next to the plan name and choose Plan settings.
   2. Select group settings.
   3. Under Manage group email, verify Don't receive any group messages is not selected if email-based notifications for comments are required.
   4. Choose Save.
3. Confirm Teams-side Planner/Tasks notifications
   • If Planner is used inside Teams, admins can disable Planner Teams notifications by disabling the Planner app for Teams. Confirm with the Teams/tenant admin that the Planner app is still enabled.
   • If only Planner Teams notifications were disabled by support or admin, contact Office support to re-enable them as noted in the documentation.
4. Check Teams mobile notification behavior (if the issue is on mobile)
   • In the Teams mobile app, go to profile picture → Notifications and ensure Show notifications is on.
   • On the mobile device, open Settings → Notifications → Teams and ensure Allow notifications is enabled.

If notifications stopped specifically after a recent update and all settings are confirmed, this may be a regression introduced by that update. In that case, collect details (client version, platform, tenant) and open a support ticket with Microsoft 365/Office support so the issue can be escalated.
