Update - 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.

Update - The rollout is now expected to begin in the early part of the next week. No additional customer action is required beyond what was previously communicated.
Private Chat History (PCH) will not be supported following this deployment as part of an ongoing re-implementation initiative. This work is intended to deliver an improved PCH experience, and PCH support will be reintroduced in a planned upcoming release.

Investigating - 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.
