Dear @Senthil kumar

Thank you for reaching out and for sharing the issue. I understand that you receive notifications, but Microsoft Teams does not open or update properly.

Based on the behavior described, this issue is commonly related to the Teams desktop client not loading correctly or having corrupted cached data. In this case, here are some troubleshooting steps I recommend you try:

Step 1: First, please ensure that Microsoft Teams is completely closed by right clicking the Teams icon in the taskbar

Step 2: Clear Teams cache

Clearing the cache on your device may help. After you clear the cache, restart Teams. For more information and instruction, please follow this article: Clear the Teams client cache

Step 3: If the problem persists, try completely uninstalling and reinstalling it. 

• Uninstall first: Uninstall Microsoft Teams
• Then reinstall: Download Microsoft Teams Desktop and Mobile Apps | Microsoft Team

Moreover, could you access Teams via the web browser? and are other users in your organization are experiencing the same issue, or if it is only affecting your account.

Note: Please understand that as a forum moderator, my role is to provide general guidance and troubleshooting support. I don’t have access to internal systems or backend tools, and I appreciate your understanding of these limits.

I hope the information shared helps point you in the right direction. Please try the steps above and let me know if they work. If not, we can continue working together to narrow this down.

The first response may not always resolve the issue right away, but with your help and more details, we can work toward a solution.

Thank you for your patience and understanding. I'm looking forward for your reply.

The desktop Teams client is failing to load properly. Use these steps to restore it:

1. Fully quit and restart Teams
   • On Windows, go to the taskbar, right‑click the Microsoft Teams icon, and select Quit so the app closes completely.
   • Start Teams again and check whether chats and teams load.
2. Verify network connectivity
   • Open a browser and confirm that other websites load.
   • If the network is fine, try using the web version at https://teams.microsoft.com to confirm the account itself works.
3. Sign out and sign back in
   • If Teams opens but is stuck or not updating, select the profile picture in the top right (if visible) and choose Sign out.
   • After Teams closes, open it again and sign in with the work or school account.
4. Clear the Teams cache (desktop app)
   • Quit Teams from the taskbar icon.
   • In File Explorer, open %appdata%\Microsoft\Teams.
   • Delete the contents of this folder.
   • Start Teams again and sign in. This removes cached web content and local history but does not uninstall Teams.

If the desktop app still shows only a blank or white screen after these steps, continue using the web version and contact the organization’s IT administrator, who can also review network/firewall settings and client health as described in the admin documentation.
