This can be configured in the same way as sending files to Oxford users, specifying external recipients by email address. In some cases a warning may be displayed when you enter the external recipient email address to remind you that you will be sharing content outside of our organisation, however this does not prevent you from proceeding. A file sharing link will be created for you to send to the recipients.
Both Oxford and external recipients can be given access through a single share.
We recommend that you use the "message" option to provide guidance for external recipients on how to access the shared file. Here is some suitable text:
Please use the link above to access a file that has been shared with you by a member of the University of Oxford. When prompted to login, please enter your email address as the username. You will then be sent a verification code to access the file. Further guidance is available at: https://help.web.ox.ac.uk/oxfile-migration-to-onedrive#collapse4881516
Warning 1: File and folder names may be exposed
Even where the sharing link does not contain the name of the shared file or parent folders, these details may be exposed when the sharing link is accessed. In some cases this happens before the recipient email address is checked (see below) so could expose file and folder names to any who obtains the link. If you do not want to share this information then we suggest that you create a new top-level folder in OneDrive, and share a copy of the file with a suitable name from here.
Warning 2: Edit access allows re-sharing
If you give Edit access to a file, then the person you are sharing with can reshare the file to absolutely anyone, including other external recipients. You will be notified of any additional sharing, can easily check who the file has been shared with, and can remove permissions.
Warning 3: Sharing directly and via a link is the same for an external recipient
If you are familiar with the difference between granting direct access to a file vs sharing via a link for internal users, then you should note that sharing with an external user always works as if you granted direct access.
