Planner -how to get notifications in Teams when comments are added to a task

Hi @Mark C, 

Thank you for posting your question in the Microsoft Q&A forum. Based on my research, the default behavior in Planner is that email notifications for task comments are only sent to users who have already participated in that task’s comment thread. Task assignees who haven’t commented yet won’t automatically receive notifications when others add comments. This design helps reduce notification overload, but as you pointed out, it creates the exact scenario where team members might miss important updates unless they check tasks manually. 

Unfortunately, there’s no out-of-the-box setting in Planner or Teams to change this behavior. I hope you can understand that, as a forum moderator, my role is to clarify and confirm the default settings for you, I’m not able to modify or override these configurations, as that falls under the responsibility of the product engineering team. 

That said, after researching further based on your needs, one possible approach is to use Power Automate. While Power Automate doesn’t provide a direct trigger for Planner comments, you can work around this by leveraging the Office 365 Groups Mail connector to monitor the group mailbox. When a comment is added to a Planner task, an email is sent to the group mailbox; Power Automate can detect that email, trigger a flow, and then send a Teams message or an email notification to the relevant people. 

For a detailed example, you can refer to this guide 

If you review the suggested approach and feel it’s suitable, then during the process of building this flow, if you get stuck or have any additional questions, I recommend posting in the Microsoft Power Platform Community Forum Thread.  

Apologies for redirecting you to a different community, but I want to clarify that this category mainly focuses on Microsoft Teams concerns, out-of-the-box features, and configuration. Members here (including myself) typically have limited knowledge about Power Automate. To make sure you receive the most accurate and helpful guidance, posting in the Power Platform forum will connect you with the right experts and other partners who regularly share their knowledge and learn from similar interactions. I hope you can understand this recommendation. 

Thank you again for raising this question. It’s a great one and really highlights an important gap in the current functionality. If this answer helps you understand the current limitations and points you toward the right resources or channels, I’d truly appreciate it if you could click “Accept answer” for this post. Doing so will make it easier for others with the same concern to find this information. 

If you have any additional questions within my scope here, feel free to ask, I’ll do my best to assist. Wishing you success in implementing the solution and a smooth experience ahead!
