| 2025-06-14 | MC How Affect | This change only impacts organizations that have already enabled or plan to enable SharePoint and OneDrive integration with Microsoft Entra B2B.
After integration, all new external sharing will use Microsoft Entra B2B Invitation Manager. Previously shared links that used the SharePoint One-Time Passcode (OTP) will no longer work. External users attempting to use these older links will encounter the error message "Sorry, something went wrong. This organization has updated its guest access settings. To access this item, please contact the person who shared it with you and ask them to reshare it with you." Impact to end users: External users will lose access to content shared via SPO OTP links created before Entra B2B integration. To restore access, users must reshare the file, folder, or site with the intended external collaborators. If the original sender is unavailable or lacks permission, another authorized user must reshare the content. No changes are required to the sharing process-users can continue to share content as they always have. | All users in every tenant that has already enabled or in future, will enable SharePoint integration with Entra B2B are impacted. Your external users will lose access to all the files, folders and sites shared before enabling this integration. To give access again, resharing is required. After the integration is enabled, external sharing will use Microsoft Entra B2B Invitation Manager
