How to change the waiting room illustration in Teams webinar?

Hi @Go-getter,

Good day anh thank you for posting in Microsoft Q&A Forum.

To answer your question: currently, Microsoft Teams does not offer a built-in feature to customize the default waiting room illustration you mentioned as shown in screenshot below.

If possible, I recommend that the organizer join the meeting a bit earlier than the scheduled time and use a PowerPoint slide or a custom banner app to share their screen. This way, when participants join, they’ll feel reassured that they’ve entered the correct webinar and see a more personalized welcome.

However, thank you for sharing great question in the community. Your concern contributes to the ongoing improvement of Microsoft products. If this feature would significantly impact your workflow, I recommend you suggest your idea in Microsoft Feedback Portal and share your feedback link here and you can mark this reply as accepted answer, this will help others in the same situation find the information better and the appropriate channels.
