Create a feature/chat/personal notes/personal chat where you can send things to yourself
I went under 'chat'. I thought I could send a message without adding anyone in the chat with the intention to send something to myself. It did not go through and it said that I needed to add someone to the chat before sending that message.
I hope Microsoft Teams can look into this and soon everyone will not need to send emails over and over just for a piece of document. Soon everyone will have a classified list of notes, documents and ideas just by sending things to themselves using Microsoft Teams.
