Additionally, when you're editing an Office file from within Teams, you can rename it by selecting the name of the file or by selecting File > Rename.
If you open an Office file outside of Teams using Office for desktop or Office for the web, you'll also be able to rename and move or save a copy from there.
Note: You don't need to copy a file to share it in multiple channels. Instead, share a link to it.
