A nice feature of Microsoft Teams is the ability to Edit a Chat response, but users should be aware that the ability to edit a response (s new chat conversation or reply) seems to expire after a certain amount of time has passed.
It appears from my testing (and I am not 100% sure) that responses dated today can be edited and after they are no older than that they can not be edited.
- It does not seem to be triggered by a reply from my testing
So as long as not too much time has passed you can edit as often as you wish. The chat will show a little pencil (shown below) to indicate that it has been edited by the original contributor. Unlike Facebook you cannot see the edit history.
Enjoy Microsoft Teams!
