We have upgraded our Microsoft 365 authentication to Microsoft’s modern identity platform (v2) to improve security, reliability, and configuration experience. Known Issues: OneDrive Migrations (Delegate App) Customers using the Advanced Option ForceOneDriveNonGlobalAdminAuthExport=1 may experience credential failures. This option remains functional for SharePoint-to-SharePoint migrations. Recommendation: Remove this advanced option if possible and assign the SharePoint Administrator role to the Delegate account. This issue is under investigation. Tenant-to-Tenant Coexistence (Free/Busy Setup) Organizational relationship creation is currently failing for coexistence projects. Workaround: If free/busy is not required, create a standard mailbox project without coexistence. We are actively investigating and will provide updates as available.
This incident is now resolved.
Migration jobs continue to process, but stopping them from the MigrationWiz UI is working inconsistently. Please contact Support if you require any migration lines to be stopped. Monitoring We have implemented a change and are seeing previously stalled migrations being processed. We are continuing to monitor the situation.

While the earlier issues have been resolved, customers who reset their password today will need to reset it again. For customers who did not update their password today, their previous password should now work.
This incident has been resolved.
MigrationWiz is currently experiencing a login issue. This is not a security incident. Users encountering the issue and receiving an “Access Denied” error should reset their password, which will restore access. We are investigating the cause and will provide an update soon.

We are currently investigating an issue affecting document migrations involving Google Drive, OneDrive, and SharePoint. Customers may experience intermittent authentication or connectivity errors when running migrations in these areas. As a temporary workaround, re-running the affected migration items typically resolves the issue. Our engineering team is actively working toward a permanent resolution. We appreciate your patience and will provide additional updates as soon as they become available.
We have implemented a series of platform enhancements to improve authentication reliability and connections for document migrations across OneDrive, SharePoint, and Google Drive. These updates have strengthened the way secure connections are established and managed, resulting in more consistent credential validation and reduced authentication-related disruptions. In addition to improved reliability, we have also made optimizations to enhance data transfer speed and throughput. These changes help migrations complete faster and more efficiently, particularly for large volumes of data or high-concurrency migration scenarios. As of our most recent deployment on June 30, we are are seeing very promising results We will continue to monitor the platform to ensure stable performance and a seamless migration experience for all users.
We have confirmed through comprehensive testing and positive customer feedback that our recent platform enhancements have successfully resolved the reported performance issues affecting authentication reliability and connection stability during document migrations. If you continue experiencing any challenges related to authentication or connection reliability while using MigrationWiz, please reach out directly to our Support team for assistance. Thank you for your patience as we worked to address this matter.
We are currently investigating migrations that are failing with the error: “The method or operation is not implemented.” in some Microsoft Teams and Sharepoint migrations.

As of March 31, 2025, Microsoft has ended support for app-only authentication in the OneNote API. To maintain functionality, users must switch to delegated authentication. This is a Microsoft platform change, and MigrationWiz cannot mitigate this. Microsoft’s Official Announcement(https://learn.microsoft.com/en-us/graph/api/resources/onenote-api-overview?view=graph-rest-1.0) Using Delegated Permissions for OneDrive, SharePoint, and Teams migrations(https://help.bittitan.com/hc/en-us/articles/360038153373-Using-Delegated-Permissions-for-OneDrive-SharePoint-and-Teams-migrations)
As of March 31, 2025, Microsoft no longer supports app-only authentication for the OneNote API. If you need to migrate OneNote files, you must use delegated permissions in accordance with Microsoft’s changes. For more information, please review our Help Center article(https://help.bittitan.com/hc/en-us/articles/360038153373-Using-Delegated-Permissions-for-OneDrive-SharePoint-and-Teams-migrations). If you have any questions, feel free to contact 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.
This informational notice about Microsoft’s upcoming EWS access changes is now closed. No further updates are expected. Please ensure your organization has made the necessary adjustments to avoid service disruption

BitTitan is aware of a Certificate issue impacting all OneDrive, SharePoint, and Teams migrations. We are actively working to resolve the error.
The certificate issue for OneDrive, SharePoint and Teams migrations has been fixed. Please resubmit any failed migrations.
Due to an ongoing Microsoft service degradation, some O365 Mailbox Migrations may become stuck in the migrating phase. These mailboxes will appear not to be moving any data for an extended period. The workaround at this time is to Stop the migration and Resubmit the mailbox. In most cases, the new connection will bypass the issue, and the mailbox migration will be complete. In some cases, specific mailboxes may need to be Stopped and Resubmitted again.
We believe we have located the root cause of the stalling O365 mailbox migrations, which was amplified by the Microsoft Service Health issue last week. We are preparing a code fix, with a target release for today 12/4 in the late afternoon US time, which we anticipate will resolve the Stalling Mailbox issue.
After a successful MigrationWiz release on 12/4, we are no longer seeing issues with Stalling Mailboxes.
We are currently experiencing a known issue with the Google API due to recent changes made by Google. These changes are causing extreme throttling and slowness in our services. To mitigate this issue, we recommend using the Google (IMAP) connector for all Google Mail migrations until we can resolve the problem. We apologize for any inconvenience this may cause and appreciate your understanding as we work to address this issue.
We have collaborated with Google and implemented the necessary algorithms to mitigate the throttling issue. The Google API endpoint is now stable and can be used for all new migration projects. Please note, for mailboxes that have already been migrated using the Gmail IMAP connector, continue using that connector to avoid any potential data inconsistencies. The Google API endpoint should be used for new mailbox migrations only.
