10 blocks taking you from zero to job-ready on Exchange Online. Every lab mirrors a real task a messaging engineer or M365 administrator runs in production — connecting via EXO V3, managing mailboxes, controlling mail flow, locking down security, enforcing compliance, and automating repetitive work at scale. No GUI hand-holding.
End-to-end break-fix across mail flow, security, compliance, and permissions. Tenant migration simulation, incident triage, and a full Exchange Online environment built from scratch via PowerShell.
