M365 Administrator
Tenants, Exchange Online, Teams, SharePoint, Entra, the productivity plane of Microsoft shops.
A real seat with a soft ceiling. Useful experience, narrowing market, easy to outgrow within three years if you don't broaden.
- Domain

- Entry
- £42–62k
- Senior
- £105–145k
- You like SaaS administration and tenant-level work
- You're patient with vendor changes that arrive without warning
- You enjoy the identity, governance and security adjacencies
- You'll use it as a base for Azure or security work
- You want hands-on infrastructure work, you won't get it here
- You can't bear vendor support cycles
- You'd resent being the person who explains email flow to leadership
What "doing well" looks like in the seat
- Your tenant configuration is documented, reproducible and reviewed
- You catch licensing waste before finance does
- You can run a Defender for Office tuning cycle that actually reduces noise
- You're picking up Entra, Intune or Defender alongside the basics
The pure M365 admin role is increasingly absorbed into broader modern workplace or identity teams. People who stay in a narrow tenant-only role get pigeonholed and find the next move harder than it should be. Treat M365 as a launchpad into Azure administration, Entra identity engineering, or Defender / Sentinel, and start steering the work that way as soon as you can.
