Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hi @lst126
First of all, you can't send video to each other directly from the chat box.
You can save the video file locally or in your OneDrive, and share the file with the other party in the chat box.
Additionally, Teams currently supports sending short video clips using the chat box, accessed by clicking the small camera icon in the Teams text chat box next to the "Send" button. From there, a pop-up screen allows users to record short clips and edit length before posting to Teams chat.
