SPO Tidbit – Change to external users in O365


Hello All,

Microsoft is updating the behavior and governance of access by external users in Microsoft Office 365. After 3/23/2018, an external user will see only the content that’s shared with that user or with groups to which that user belongs. External users will no longer see content that’s shared with EveryoneAll Authenticated Users, or All Forms Users. By default, content that’s granted permissions to these groups will be visible only to your organization's users.

Administrators can change the default behavior to enable external users to see content that's with EveryoneAll Authenticated Users, or All Forms Users.

Further if you want to discover what external users have access to follow the steps in this article KB 4089174: How to determine resources to which all external users have access

Why this change?

By updating the behavior and governance of access by external users in Office 365, Microsoft is providing Office 365 customers with a behavior that is safer for content permissioned to Everyone, All Authenticated Users, or All Forms Users. Please see KB 4089534 How to govern access of external users in Office 365 for more information.
