* Configure and manage hybrid Exchange environments and coexistence models where required (e.g., ADFS, Azure AD Connect, Hybrid Configuration Wizard).
* Troubleshoot migration issues, including mail flow, directory synchronization, Outlook connectivity, and data migration errors.
* Collaborate with security and compliance teams to ensure migrations meet organizational and regulatory requirements (e.g., GDPR, ISO 27001).
* Engage with business stakeholders and change management teams to drive user readiness and adoption.
* Provide technical guidance and escalation support during critical migration phases and post-migration hypercare.
