Dear @Holzel, Giselle E,
Thank you for reaching out to the Microsoft Q&A forum. I am happy to assist you.
To better understand the issue and provide accurate guidance, could you please share a few additional details?
What type of camera are you using? Is it the built‑in camera on your computer/laptop, or an external webcam?
Does the zooming occur in other meeting apps, chat apps, or the Windows Camera app?
Have you tried using Teams for the web to see if the behavior is the same?
Providing this information will help me narrow down the cause and assist you more effectively and, if necessary, route your request to the appropriate team for further assistance. Looking forward to your response so we can assist you further!
