In order to share references, you need access to your EndNote online library. Basic users will always be online and don't need to worry about syncing anything.

References can only be shared if they're in groups. ” Each group has a sharing option represented by a tiny box. Once you've clicked it, hit “manage sharing,” then “start sharing this group.” You can then enter the email address of the person you'd like to share with.
