In the example below, we're sharing a file using the Box for Office plug-in in Outlook. When you select the level of access for the file or folder, select People with the link.

If you want to restrict access to the file or folder so nobody outside of PATH can open it, then select People in your company. This prompts recipients to log in with PATH credentials before they can view the file. NOTE: The recipient must have an active Box account to use this option.
