BitTitan incident
Modernized Microsoft 365 Authentication for Better Security & Ease of Use (Update)
Resolved after 74 days 16 hours, affecting MigrationWiz and MigrationWiz DE, on February 13, 2026.
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.
