Official incident page

Incident Report

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 and Teams 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.
