Hi @Amy Burford ,
When enabling Microsoft Entra B2B integration with SharePoint, it does not inherently change your existing sharing settings.
To troubleshoot this, you may want to review the organization-level sharing settings and the specific site settings to ensure they align with your intended access controls. Additionally, it’s important to check if the integration has inadvertently changed the permissions for existing users. By checking whether each user has the original permissions for these files.
