When Hybrid Identity Breaks, Starting Over Isn't the Only Option

The Challenge

A Critical Migration Stalled by Hybrid Identity Failure

Archbright, a Human Resources services organization, was ready to retire its legacy on-premises identity infrastructure and move fully to cloud-managed Microsoft 365 identities. The business had already eliminated applications dependent on its legacy domain and was preparing to decommission the remaining environment.

But during the migration, something broke.

User accounts became stuck in a hybrid state where Self-Service Password Reset (SSPR) stopped working entirely. Standard migration procedures failed. Microsoft’s recommendation was to delete and recreate more than 100 user identities.

For Archbright, that was not a viable path forward.

The situation created immediate operational and security concerns:

• Users could not reset their own passwords, forcing administrators to manage manual resets across the organization.
• Compliance and password rotation requirements were at risk, increasing exposure.
• Rebuilding identities would disrupt SharePoint, Teams, and Exchange data tied to those accounts.

 What began as a cloud modernization initiative quickly became a blocker, preventing Archbright from retiring legacy infrastructure and moving forward confidently. 

The Solution

A Smarter Path Forward, Without Rebuilding Identities

When rebuilding more than 100 user identities became the default recommendation from Microsoft, Archbright needed a better option.

Instead of starting over, Teknologize evaluated the environment at a deeper level. After isolating the root cause of the hybrid identity failure, we identified a way to safely convert accounts to cloud-only status without deleting a single identity.

Rather than rebuilding users and repairing permissions afterward, we preserved everything already working,  SharePoint access, Teams channels and chat history, Exchange mailboxes, and existing security controls.

The approach focused on three priorities:

• Preserve all existing data and permissions
• Restore self-service password functionality
• Eliminate hybrid identity complexity without disrupting users

After validating the solution in a controlled test environment, the migration was executed across Archbright’s tenant, safely and without user interruption.
