Profile
Ryan O'Connor founded Accred Consulting and leads its architecture work. Ryan designs, delivers and optimizes enterprise Microsoft 365 environments, from legacy on-premises estates to modern cloud tenants, and leads complex migrations and M&A integrations with security and compliance built in from the first design.
Every design is tied to a business outcome. Return on a Microsoft 365 investment comes from automation and real user adoption, not licenses sitting idle, so Ryan's engagements cover the change management and enablement that make new tools stick.

- Migrations and M&A integration. Exchange, Google Workspace to Microsoft 365, tenant-to-tenant consolidation and hybrid Exchange.
- Identity and access. Entra ID, on-premises Active Directory, hybrid identity and federation.
- Security and compliance. DLP, retention, governance, penetration testing and audit readiness.
- Adoption and enablement. Training and change management that produce measurable gains in utilization.
