How to share files

You may want to share files with team members, either with the entire group or a specific person. 
  1. At the bottom chat field, click the paper clip icon. You can attach a file from your computer or your shared OneDrive storage.
  2. Select the file you want to share, such as an Excel spreadsheet.
  3. Send it to the recipients. All of you can now click the file to open it in Excel's web app. You and the other members can edit the file in real-time with any edits pointing to the name of the person who made the change (Figure I). 
  4. Close the file when done. Any files attached this way are saved in Teams and are accessible through the file attachment location for Teams and Channels.
