What is a secure program similar to Teams, but you do not need a MS email to use?

I am in need of a program like Teams, but one where the users can have any email address, not just MS. The users have gmail, yahoo, and some .edu accounts. I am trying to get as close to Teams as possible, in the sense that, they can chat, send files, and have meetings all in one place. Preferably something not expensive or even free (probably a long shot, I know).
