You can share a Drive 365 file with team members of your organization and people outside the team. Note that if you share a project to users outside the team, those users will be able to open and edit the project but not to overwrite it. They will have to save it to their local device or to a Cloud location.

Also, anyone who has been forwarded the project, will not be able to open it, getting a “You don’t have permission to access this project” message.
