Description

Independent Consultant – Expert Microsoft Exchange & Microsoft 365

For over fifteen years, I have been helping companies transform, secure, and modernize their Microsoft messaging. Specializing in Exchange On-Premise, Exchange Online, and complex migrations, I intervene when service continuity, security, and technical mastery are essential.

I help organizations to:

- Successfully complete their messaging migrations (Cutover, Staged, Hybrid, IMAP, Tenants-to-Tenant)

- Stabilize and optimize their Exchange environments (On-Prem, Hybrid, Cloud)

- Resolve critical incidents (transport, high availability, Autodiscover, DNS, mail flow…)

- Harden and secure the infrastructure (SPF, DKIM, DMARC, MFA)

- Write and define clear SOWs, audits, and action plans

- Accelerate Modern Workplace projects around Microsoft 365

Each mission is based on:

- Precise technical analysis and a deep understanding of business challenges

- Realistic & actionable recommendations

- Clear communication with IT teams, project managers, and management

- A results-oriented approach, with complete documentation and skills transfer

Are you preparing for a migration, experiencing an incident, or looking to secure your messaging?

I can help you quickly.
