Troubleshooting & Support

  • Compliance Controls: Implement and manage retention policies, litigation holds, journaling, eDiscovery, DLP, and audit logging.
  • Identity & Permissions: Partner with identity teams to enforce least-privilege access, role-based administration (RBAC), and strong authentication.
  • DNS & Certificates: Own DNS records related to email services and configure SPF, DKIM, DMARC; manage SSL/TLS certificates used in mail flow and hybrid configurations.

Migrations, Upgrades & Automation
  • Messaging Migrations: Lead mailbox migrations, tenant-to-tenant moves, and upgrades from on-prem Exchange to Exchange Online.
  • Change Management: Plan and execute platform changes with minimal business impact, following formal change control processes.
  • Automation: Develop and maintain PowerShell automation for provisioning, reporting, compliance tasks, and operational efficiencies.

Messaging Resiliency & Continuity
  • Backup & Recovery: Support backup, recovery, and continuity strategies for messaging systems in alignment with enterprise DR standards.
  • Business Continuity: Partner with infrastructure teams to ensure messaging services meet RTO/RPO requirements.

Documentation & Collaboration
  • Operational Documentation: Maintain architecture diagrams, configuration documentation, runbooks, and support procedures.
  • Cross-Team Partnerships: Collaborate closely with Security, Infrastructure, Microsoft 365, and Help Desk teams to ensure cohesive service delivery.
  • Audits & Reviews: Provide documentation and evidence to support internal and external audits as required.

Education/Learning Experience
Required: Bachelor's degree in IT, Computer Science, or a related field (or equivalent experience)
Desired: Masters's degree in IT, Computer Science, or related field
Work Experience
  • Required: 5+ years administering Microsoft Exchange environments in a mid-to-large enterprise, including Exchange Online and hybrid deployments.
  • Desired: Experience supporting regulated environments (e.g., healthcare, pharmaceutical, finance) and compliance-driven messaging controls.

Skills/Knowledge
  • Required: Expert-level knowledge of Microsoft Exchange (Online and on-prem), Exchange hybrid architecture, and mail flow design. Strong experience with email security platforms and Microsoft Defender for Office 365. Deep understanding of SMTP, DNS, SPF, DKIM, DMARC, and TLS. Proficiency with PowerShell for automation, reporting, and troubleshooting. Working knowledge of Active Directory, Entra ID (Azure AD), authentication, and RBAC.
  • Desired: Experience with tenant-to-tenant migrations and complex coexistence scenarios. Familiarity with Microsoft Purview compliance capabilities. Exposure to Zero Trust and modern identity security models

Licenses/Certifications

  • Desired: Microsoft Certified: Security Administrator (SC-200)
