Marcus Whitford

Marcus spent 11 years on enterprise helpdesks before moving into MSP team lead work - first at a 400-seat law firm running a hybrid AD/Entra environment, then four years at Rackspace handling escalations for mid-market M365 tenants. He holds MS-102 (Microsoft 365 Administrator Expert) and the older MCSA: Windows Server, and writes most of the Intune and Conditional Access material here. His subspecialty is the messy middle of M365 migrations: tenant-to-tenant moves, the OneDrive known-folder-move rollout that breaks half a department's desktop shortcuts, and the Conditional Access policy that locks the CEO out at 6am on a Monday. He has personally rebuilt three Exchange hybrid configurations after botched cutovers and still keeps a printed copy of the Hybrid Configuration Wizard logs on his desk as a warning. Outside work he restores 1990s ThinkPads and runs a small home lab on refurbished Dell R730s.
