When adding a file to an email in Outlook and using the Box for Office integration to upload it to Box and create a shared link, you have the option to make the link visible to Invited Users Only. However, when doing this, it does not add all users as collaborators to the file so they can access the shared link. Ideally, the integration should add the users CC'd in the email ass collaborators if they are not collabed already so that they can access the Invited People only link
