Good day @Indrasena Reddy Pothapu,
Thank you for posting in Microsoft Q&A Forum.
From what you've shared, I truly appreciate your effort with the trouble you're experiencing with Screen Sharing and Call in Microsoft Teams, and I also notice you’ve already followed the common troubleshooting steps available in public resources.
Therefore, the best next step that we can provide for your better solution is raising a support ticket through the Microsoft 365 Admin Portal, this will connect you with Microsoft’s technical support team, who can provide a more direct and effective solution for your case. They can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis.
Please accept my apologized because, as forum moderators, we don’t have access to the detailed logs or backend systems needed to troubleshoot this effectively due to privacy and security constraints. For that reason, the most efficient solution would be to contact Microsoft’s support team directly.
To create the support ticket, the Global Admin (the person who can manage all accounts in your organization) should create a service request by refer to instructions on how to get support: Get support - Microsoft 365 admin | Microsoft Learn.
If you’re unsure who the Global Admin is within your organization, you can find guidance on locating them here: How do I find my Microsoft 365 admin? - Microsoft Support.
Thank you for your patience and understanding. If you have any further updates, please feel free to let me know.
