Blocking externally shared SharePoint files RRS feed

  • Question

  • Hi

    Is there anyway within SharePoint that we can block external users sharing files into users in our domain?

    We have discovered that any user externally can share files with our domain users without restriction and our security team have flagged it. Rightly so.

    We can look at attempting blocking these email requests coming in but that is proving difficult as there will be occasions this is required and authorised.

    Is there any way within SharePoint itself to control this?

  • If your external users are uploading files to SharePoint, then you can limit their permissions on the library or site.

    Give them only read permissions.
