   MigrationWiz document Migration Errores Tras una actualización del sistema el 19 de agosto de 2026 que mejoró la velocidad y el rendimiento generales de la migración de documentos, hemos identificado un problema que afecta a un pequeño subconjunto de clientes. Algunos usuarios pueden encontrar uno de los siguientes errores durante las migraciones de documentos: "Colección fue modificada; la operación de enumeración no puede ejecutarse." "Offset and length were out of bounds" "No había leído todos los bytes del archivo." Estos errores no son indicativos de la pérdida de datos. Son el resultado de una actualización de DLL incluida en la versión de agosto de 19, que hace que los registros generados antes de la actualización no sean legibles por el código actualizado. Somos conscientes de la cuestión y trabajamos activamente en una resolución más amplia. Pasos recomendados Si usted está experimentando uno de los errores anteriores, por favor realice un Reset Items y vuelva a presentar el pase de migración. Esto resuelve la cuestión en la mayoría de los casos. Para obtener instrucciones, consulte Cómo restaurar artículos en MigrationWiz. https://help.bittitan.com/hc/en-us/articles/360042167494-MigrationWiz-Statistics-Statistics-Lookup#01H8HEMGW00PCG8XHWPM7QHWJD Si el error persiste después de realizar un Reset Items, por favor abra un caso de soporte para que nuestro equipo pueda ayudarle directamente mientras trabajamos en una solución más amplia. Vamos a proporcionar actualizaciones aquí mientras nuestra investigación continúa.

   Late next week, we will begin rolling out a security-enhancing update to our authorization flow. As part of this update, a small set of workloads require user action to continue running successfully. OneDrive, SharePoint and Teams Collaboration endpoints using delegated permissions will need the Tenant ID added in the Endpoint Settings page and PKCE consent completed. BYO app registrations will no longer function and must be switched to the BitTitan app. For full instructions and details, please refer to the guidance pages below: Required Actions & Resolution Guide [https://help.bittitan.com/hc/en-us/articles/43575952076827-Post-Deployment-Action-Items] Endpoint Settings Guide [https://help.bittitan.com/hc/en-us/articles/42628192621211-Endpoints-Setting-Guide] Consent Flow Guide [https://help.bittitan.com/hc/en-us/articles/42629928893851-Project-Summary] This notice is informational to ensure customers can complete the necessary updates.

   Update: Resolved Issues, Known Issues & Workarounds Following the recent deployment, we have identified a small number of edge-case scenarios that may affect specific configurations. Most have simple workarounds, and our teams are actively addressing these issues. Resolved Issues : The following issues identified after deployment have been resolved: 1. SSO sign-in for SSO-enabled domains An issue that prevented users from logging in using SSO-enabled domains has been resolved. 2.SharePoint auto-discovery SharePoint site auto-discovery is now functioning as expected. We are actively working to address these scenarios and will provide updates as improvements are rolled out. If you experience issues outside of the cases described above, please contact Support for assistance. Known Issues : M365 Mailbox Issue: Scoping Some customers, who are using scoping functionality, are receiving the error: “Your migration failed while checking source credentials. Validate Token failed, please check EWS Application Permissions in Azure App.” This is currently under investigation. Recommendation: If possible, run your project without using scoping. The migration should complete successfully. Delegated Consent may return a 500 error : In some cases, attempting delegated consent may result in an internal server error. Workaround: Edit the project, save it without making changes, and then retry the consent flow. This resolves the issue in most cases. Consent may reference a previously configured tenant after changing endpoints : If a project’s source or destination endpoint is edited to point to a different tenant, the consent flow may still attempt to authorize the previously configured tenant. Workaround: If the project has not been started, create a new project using the updated tenant details. Consent banner may not appear for specific Google → Microsoft 365 (v3) document migration scenarios In certain edge cases, the consent-required banner may not display even when consent has not yet been provided. Recommendation: Review the Project Summary page and confirm that the consent status shows Authorized / Consented before starting the migration Consent banner may not refresh after editing project endpoints When editing a project and changing tenant or permission settings, the consent banner may not immediately reappear. Recommendation: Verify the consent status from the Project Summary page to ensure authorization is complete.

5. 26 de enero de 2026 a las 13:31 UTCidentified

   Update : Our teams continue to actively investigate and address the remaining items identified after deployment. Below are the latest updates and recommendations. M365 Mailbox Issue: Scoping Some customers using scoping functionality may encounter the error: “Your migration failed while checking source credentials. Validate Token failed, please check EWS Application Permissions in Azure App.” This remains under investigation. Recommendation: If possible, run your project without using scoping. The migration should complete successfully. If scoping is required and the above recommendation does not resolve the issue, ensure the source application includes the additional permission Exchange.ManageAsApp, and follow the steps outlined in below document. Document Link: [M365 Mailbox and Archive Migrations - Scoping Option for API Permissions](https://help.bittitan.com/hc/en-us/articles/27712633347099-M365-Mailbox-and-Archive-Migrations-Scoping-Option-for-API-Permissions#h_01J3NXCYXSE6V647FTHKRPR2KX) ----- Tenant-to-Tenant (T2T) Coexistence – Organizational Relationship Creation Tenant-to-Tenant coexistence projects are currently unable to complete the required cross-organizational free/busy setup process. Workaround: If free/busy availability between tenants is not required (typically only needed for large, long-running coexistence projects), we recommend creating a standard MigrationWiz mailbox project without coexistence while we work to resolve this issue. ----- We appreciate your patience and continued cooperation as we work to fully resolve these items. Additional updates will be shared as progress is made.

   We are continuing to work on a fix for this issue

7. 30 de enero de 2026 a las 3:06 UTCidentified

   Update : We have upgraded our document migration authentication to modern authentication standards for SharePoint, Teams, and OneDrive. This enhancement strengthens security, improves reliability, and aligns our migration platform with current Microsoft 365 identity best practices. As part of this upgrade, legacy authentication mechanisms such as SharePoint IDCRL are no longer used. Customer Impact: Migration projects using delegated permissions (SharePoint, Teams, or OneDrive) will fail until permissions are re-consented. To continue, customers must re-consent the delegated permissions and then re-run the migration. For more information, please review our release note. We remain committed to continuously improving the security, reliability, and quality of our migration platform. If you have any questions, please feel free to reach out to our Support team.

   Microsoft has announced a change to Exchange Web Services (EWS) access in Exchange Online, effective at some point in April 2025 (Microsoft has not provided a specific date for this change). Once this change has been made, EWS access will only be allowed if both the organization-level and user-level EWSEnabled flags are set to True. To avoid any service disruptions, please ensure that EWS is enabled at both levels in your Microsoft 365 tenant. If either flag is set to False, EWS requests will be denied, and your migrations or services relying on EWS may fail. We strongly recommend reviewing your settings in advance. For more information, refer to Microsoft’s official announcement: 👉 [The way to control EWS usage in Exchange Online is changing.](https://techcommunity.microsoft.com/blog/exchange/the-way-to-control-ews-usage-in-exchange-online-is-changing/4383083) If you need assistance, please contact our support team.
