How to collaborate on a Google Drive file when using a non-Google account

You can share documents normally with non-Google accounts once visitor sharing has been enabled for your organisation.

They can use the link from the initial sharing email to re-verify their identity if they need to collaborate for a longer period of time. https://ift.tt/kDqQzGJ
