Sharing Externally from SPO Fails due to Users not Being Added to Correct Online Security group by Portal when Assigning the Guest Inviter Permissions – PRB0225615
We are aware of an issue preventing admins from sharing SharePoint sites from SPO with guest users. To share SharePoint sites with guest users, admins are required to be members of their organisation’s guest inviter group. When a user is a member of this group, they are granted a couple of roles in Portal for that organisation as well as tenant level permissions. Currently, users are incorrectly not being added to a security group in Entra.
