Proven experience with Exchange (on-prem) and Exchange Hybrid.
Solid practical experience with PKI (Root/Issuing CAs, templates, CRL/OCSP).
Production experience with Microsoft 365 / Entra ID in hybrid environments.
Practical knowledge of ADFS / SSO, federation, and claims-based authentication.
Strong Windows Server background in enterprise environments.
