Question about External Sharing


  • External sharing continues to be a thorn in my side... I don't always know the answers to questions I get. If a user creates a subsite (ie, personal site) in their ODB for the sole purpose of using external sharing to share documents with a vendor's MS account, will that vendor be able to see other company sites that have external sharing activated? Other sites that are open to the "Everyone" group with Visitor permissions?

  • He'll be able to see everything to which the Everyone group/claim has access. You might want to block the claim via:

    Set-SPOTenant -ShowEveryoneClaim $false 

    This will not change anything to already shared resources, so you might want to replace the permissions on those with "Everyone except external users".
