Confusing-Sharing

Hi Bruce,

To your first question, if the link is e-mailed through OneDrive & SharePoint, it will show up in the recipient user's Shared With Me view. Otherwise, once they click on the link, the document will also show up in that view. In general, when ODB/SPO can be sure that the user should have access to the content, we will try and make sure it shows up in SWM. The primary cases where we don't know are when you copy the link as then we don't know where it is being sent.

For your second question, anyone who has edit permission to the resource is able to re-share it (assuming the Members Can Share feature is enabled, I can give you more detail on this particular policy if needed). There is an additional sharing policy in the admin portal that prevents external users from re-sharing content they don't own. 

Anytime someone clicks on a link while authenticated, they will show up in the "Manage access/permissions" pane and be associated with that link. If the user is not signed in, no information is added to the permissions pane, but we do log an audit event that the anonymous link was used.

Hope that helps!
