Teams chat 1:1

Hi @Ganesh raj,

Thank you for the detailed write up and for all the troubleshooting you have already completed, including clearing the Teams cache, repairing and resetting the app, verifying the Edge WebView2 Runtime, running the repair on the latest version, and confirming the same behavior on Teams web.

I attempted to recreate the scenario you described, where an incoming 1:1 message shows as a banner notification but does not appear in the chat window until the conversation is opened manually. I was not able to reproduce it on my side, and since the behavior is intermittent and has persisted across both the desktop app and the web client after the steps already taken, the next step is to ask your IT administrator submit a support ticket through the Microsoft 365 Admin Center so the root cause can be identified.

A support ticket allows the team to review the logs tied to your tenant and account and trace why the chat is not displaying in real time. When you raise it, please include the troubleshooting steps you have already completed, the intermittent nature of the issue, and a recent example with the approximate date and time a message failed to appear.

In case you do not know who is your IT admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support  

For guidance on how to request support in the admin center, please refer to: Get support - Microsoft 365 admin.
