With Markdown, you get a live preview of your formatted text inside the compose box as you type, and you can undo your formatting at any time by pressing Ctrl+Z (Cmd+Z on Mac). Most basic formatting actions are still available if you expand your compose box. Note that Teams supports a subset of Markdown syntax; some elements, like headers and block quotes, may not render as expected.

Use Markdown to share code
- To add an inline block of code, use backticks (`) around your text.
- For multi-line blocks, use triple backticks (```) before and after your code.
- You get a live preview, and you can undo changes with Ctrl+Z.
