Teams notifications won't go away chat disabled

Hi @Auguanno, Dorian, 

Thank you for posting your question in the Microsoft Q&A forum. 

I’ve carefully reviewed the scenario you described and ran a test in my own environment. You’re absolutely right! When chat is disabled at the tenant level but not within meetings, invited users who don’t join the meeting can still receive persistent “unread” notifications if someone sends a message in the meeting chat.  

After researching further, it appears that this is a by-design behavior in Microsoft Teams. The system is designed to ensure that all invited participants, regardless of attendance, are kept in the loop for any meeting-related communication. While this helps maintain transparency and continuity, I understand it can also lead to confusion or clutter, especially in cases like the one you described. 

At this time, there is no built-in feature to bulk mark all meeting chats as read or to clear these notifications without manually identifying and opening each meeting chat. 

I completely understand your desire for a more efficient way to manage these lingering notifications. It would certainly improve the user experience and reduce unnecessary distractions. However, I hope you understand that as a forum moderator, my role is to assist based on public documentation, product behavior, and community-shared insights. I don’t have the ability to escalate or modify product features directly. 

That said, I strongly encourage you to submit this feedback to the Microsoft Teams product team via the Microsoft Teams · Community.   

This platform sends your suggestions directly to the engineering team, where they can be considered for future improvements. 

In the meantime, if my response has helped clarify the situation and pointed you toward a possible next step, please consider marking it as the Accepted Answer. This will help pin the post to the top, making it easier for others in the community who may be experiencing the same issue to find your feedback and support it. If someone has a helpful workaround or piece of advice, they’ll be more likely to see your post and share it with you.  

Thank you again for your time and thoughtful question!
