Hi @S.P Singh,
Thank you for posting your question in the Microsoft Q&A forum.
Based on your inquiry, we understand that you are looking into configuring thumbnails for PowerPoint via SharePoint Embedded in View mode. We would be glad to assist you with this process.
Here are a few suggestions that may help resolve the issue:
- Try both the app and the website: Sometimes, the issue might be specific to one platform, so you can try on both platform.
- You can try to follow these steps to configure it: You can refer to the Microsoft Support article on how to add or change a video thumbnail in SharePoint. Add or change a video thumbnail in SharePoint - Microsoft Support
If the above methods don’t work, I suggest you raise a support ticket from the Microsoft 365 admin center, where the related team can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. As forum moderators, we don’t have access to the detailed system needed to troubleshoot this effectively due to privacy and security constraints.
