Allow us to send multiple/different files with the same name to multiple colleagues
I send a file with the name (example) "Contract.pdf" to a colleague via teams.
I create a new pdf with the same name but different content
I send the new PDF to another colleague and tell teams to overwrite file (because the exact unique name is important)
The first colleague can now click on Download file via Teams and download the new file instead of either the old one or nothing at all.
For teams, create a separate folder for each chat in Onedrive to ensure that different files with the same name are sent in different chats.
