SharePoint: Entra B2B integration for external sharing in OneDrive & SharePoint

Microsoft 365 Message Center Archive by Merill Fernando
Microsoft 365 roadmap entry

Summary

OneDrive and SharePoint will use Microsoft Entra B2B as the invitation and authentication method for external users, replacing the legacy SharePoint One Time Passcode (SPO OTP) experience. External sharing will automatically create B2B guest accounts in your directory, delivering consistent external collaboration across Microsoft 365, stronger guest identity management, and modern security aligned with Microsoft Entra standards.
