One service. Every workload. One operating model.

Managed Microsoft 365 from Harrby covers identity, messaging, collaboration, security, governance, and support, delivered through a structured model that keeps the environment improving.

Governance

Structure before sprawl

Harrby applies naming standards, ownership models, guest access controls, and sharing boundaries before the environment grows beyond what anyone can govern.

Security

Identity and access, properly controlled

MFA, conditional access, identity protection, and secure collaboration settings maintained consistently.

Operations

Support that keeps improving

Harrby manages incidents, change, service requests, and health reviews through a single accountable service model with clear documentation and regular reporting.

Microsoft 365 is running your business.

Is anyone running it?

Most organisations already have Microsoft 365. What they often lack is a structured way to govern it, secure it, and keep it under control as the environment grows.

Licences were added, features were switched on, and the environment kept growing. The result is usually the same: a tenant that works well enough day-to-day but is quietly building up risk.

Guest access granted years ago and never reviewed. Conditional access policies applied inconsistently. Teams sprawl with no ownership model. Sharing settings that make security uncomfortable and governance impossible.

What M365 is now

  1. The identity layer for your organisation
  2. The collaboration backbone for your teams
  3. The communication platform replacing legacy systems
  4. Increasingly, the security boundary itself

A managed service that turns

Microsoft 365 into a controlled business platform

Expert cloud management, operational support, security uplift, and governance across Microsoft Entra ID, Exchange Online, Teams, SharePoint Online, and OneDrive for Business.

A structured operating model that defines how your Microsoft 365 environment should run, who is responsible for what, and how risks and changes are managed over time.

The right engagement model depends on your internal capability, risk profile, and how much operational ownership you want to retain.

Engagement models

Harrby owns day-to-day operations

Shared ownership with clear role boundaries

Governance and design, your team executes

Five phases.

One continuous operating model.

The first three phases are completed once. Operate and Optimise never stop.

Your environment does not drift back because an active model maintains it.

1 Discover

Harrby reviews the tenant across identity posture, email security, collaboration configuration, guest access, sharing settings, and governance maturity. All risks and gaps are documented.

Once

2 Architect

Harrby defines the target state and agrees the ownership model, service boundaries, and operating responsibilities across every workload.

Once

3 Deliver

Harrby implements configuration changes, applies security baselines, establishes governance structures, and stabilises and documents the environment.

Once

4 Operate

Harrby handles ongoing administration, incident management, service requests, health reviews, structured change, and reporting with clear, traceable ownership.

Continuous

5 Optimise

Harrby runs regular service reviews, assesses Microsoft platform changes, provides roadmap guidance, and progresses governance maturity over time.

Continuous

Six situations

where a managed service makes the most difference

If any of these sound familiar, the cost of staying as-is is already higher than the cost of changing the model.

1 After rapid growth

Your tenant expanded quickly. Governance, naming conventions, sharing settings, and access patterns are now inconsistent across teams, sites, and accounts. The environment has outgrown the model used to manage it.

2 Before a security uplift

An audit, Essential Eight assessment, ISO 27001 certification, or broader cyber initiative is approaching. Stronger control over identity, collaboration, and data sharing is needed before it begins.

3 When IT is at capacity

Your IT team is spending too much time on routine M365 administration, repeated support issues, and reactive fixes with little capacity remaining for improvement or strategic work.

4 After a migration

A rollout or tenant change has completed and you now need a stable operating model to keep the platform improving rather than letting it drift back.

5 Inconsistent user experience

Staff are dealing with access issues, unmanaged Teams sprawl, uncertain sharing practices, or a document structure that everyone knows is a problem and nobody has fixed.

6 No clear ownership

Advisory, governance, and operations are split across separate relationships. Harrby combines all three under one accountable service model.

Microsoft 365

by the numbers

One service model. Every workload managed, governed, and continuously improved.

5 Core workloads

Entra ID, Exchange Online, Teams, SharePoint Online, and OneDrive managed together as a single connected service.

3 Delivery models

Fully managed, co-managed, or advisory-led matched to your internal capability and how much ownership you want to retain.

1 Operating platform

A single M365 service layer aligned across identity, messaging, collaboration, governance, and support.

∞ Continuous

Ongoing reviews, reporting, structured change, and roadmap guidance keep the service improving.

Outcomes for your organisation

Structural improvements that come from bringing Microsoft 365 under a managed, governed operating model.

Fewer avoidable issues, stronger identity and data controls, and a better experience for everyone using Microsoft 365 every day.

Better collaboration

Teams, SharePoint, and OneDrive configured for how people actually work.

Less friction

Standardised access and lifecycle management reduce IT request volume.

Scalable governance

Naming standards, ownership models, and sharing boundaries that grow with you.

Predictable operations

Clear ownership for incidents, change, and approvals.

What Harrby manages in Microsoft 365

Eight service areas covering every layer of your Microsoft 365 environment, managed as a connected whole.

Exchange Online

Mailbox admin, anti-spam, anti-phishing, impersonation protection, and mail hygiene, maintained and operational.

Microsoft Teams

Team and channel governance, guest access, messaging policies, and meeting config. Sprawl prevention built in.

SharePoint Online

Site architecture, permissions, sharing controls, ownership models, and collaboration governance.

OneDrive for Business

Personal storage config, sync guidance, secure sharing, retention-aware settings, and endpoint integration.

Security

Baseline hardening, identity security reviews and alignment with your cyber posture.

Who this service fits best

Six organisation types where a managed Microsoft 365 service makes a material difference to security, governance, and operational continuity.

Professional services

Law, accounting, and consulting. Secure collaboration, controlled client communication, and document management across distributed teams.

Government

Commonwealth, State, and local. Access control, audit visibility, governance standards, and Essential Eight alignment are required by default.

Healthcare

Providers and community services. Reliable access management, secure information sharing, and platform stability for operational teams.

Education

Schools, TAFEs, and RTOs. Identity lifecycle, content governance, and secure collaboration for staff and learners.

Mid-market

Growing businesses at scale. Enterprise-grade Microsoft 365 management with a cost structure that works without a large internal IT team.

Hybrid and remote

Distributed workforces. A structured, secure collaboration platform covering every office, home, and client site.

The Harrby difference

Six things that separate a genuinely managed service from a bundle of licences with a support email attached.

Customers brought these up when comparing options.

Security and practicality together

Identity, collaboration, and sharing controls applied to strengthen protection without disrupting day-to-day work. Security that frustrates users gets bypassed; we design to prevent that.

Configuration, not just licences

Harrby focuses on how M365 operates in practice. Many organisations pay for capabilities they're not using safely or effectively.

Transparent documentation

Clear config notes, governance standards, and change records. Stakeholders know what's been implemented and why.

Right-sized governance

Controls scaled to fit your organisation based on your risk profile. A 50-person firm operates differently from a 5,000-person agency.

Advisory and managed together

Operational support, roadmap guidance, and Microsoft platform change interpretation through one partner and one service model.

Plain English communication

Harrby explains risks, trade-offs, and design choices in plain terms for both technical and business stakeholders.

Tenant stabilisation after organic growth

A mid-market professional services firm. Rapid headcount growth, no governance model. Nobody confident about what was shared with whom.

Challenge

Teams sites, SharePoint permissions, guest access, and mailbox configurations had grown without governance. Rapid headcount growth left the tenant inconsistent and opaque. Nobody was confident about what was shared with whom.

Approach

Full tenant review conducted. High-risk sharing configurations identified and remediated. Governance standards introduced for Teams and SharePoint. Identity and access controls tightened. Target operating model documented.

Outcome

  1. Improved security posture across the tenant
  2. Cleaner collaboration structure in Teams and SharePoint
  3. Fewer repeated support issues reaching IT
  4. Internal team managing the environment with confidence

Security uplift for a hybrid workforce

A professional services organisation needed stronger identity controls and more consistent sharing practices without disrupting a flexible team working with clients.

Challenge

Identity controls were inconsistent and sharing practices varied across the workforce. The team was mobile and worked with clients directly. They needed protection that didn't create friction or they'd work around it.

Approach

Conditional access policies implemented. MFA enforced across the tenant. Secure collaboration controls applied. Ongoing service reviews introduced to maintain posture over time.

Outcome

  1. Stronger identity protection across the tenant
  2. Consistent sharing practices applied
  3. User experience remained practical for hybrid work
  4. Posture maintained through ongoing service reviews

Co-managed Microsoft 365 for an internal IT team

A strong generalist IT team that needed deep Microsoft 365 specialisation without handing over full operational ownership.

Challenge

The internal IT team had strong generalist capability but lacked deep Microsoft 365 specialisation. They needed expert support for governance, complex changes, and roadmap decisions without handing over full operational ownership.

Approach

Harrby defined a co-managed operating model with clear role boundaries, took ownership of higher-complexity governance and security work, and provided advisory input on Microsoft platform changes. The organisation retained selected routine administration.

Outcome

  1. Stronger platform control and governance
  2. Better decision support for the internal team
  3. Reduced pressure on internal resources
  4. Cleaner escalation path for complex issues

What customers say

From organisations that have brought Microsoft 365 under a managed operating model.

Customers describe three consistent themes.

  1. Governance that improved the environment without making it harder to use.
  2. Communication that translated technical complexity into language that both IT and leadership could act on.
  3. A service that went beyond keeping the lights on.

"Harrby gave us structure around Microsoft 365 without making the environment harder to use. Their combination of governance thinking and practical support made a real difference to how our team operates day to day."

Operations and Technology Leadership

"They explained complex Microsoft 365 decisions in plain language that both our technical team and our senior leadership could understand. That clarity helped us move faster and make better decisions."

Mid-Market Services Organisation

"We needed more than administration. We needed a partner who could improve our security posture, manage change properly, and help us keep the tenant under control as we keep growing."

Compliance-Focused Customer Environment

Pricing approach

Pricing reflects tenant complexity, support boundaries, user count, and the operating model that fits your organisation.

Pricing reflects

  1. Tenant size and user count
  2. Workload mix and risk profile
  3. Support coverage requirements
  4. Onboarding effort
  5. Fully managed or co-managed model

Pricing is transparent; you will know what you are getting and what it costs.

Essentials

Smaller environments needing core administration, governance uplift, and predictable operational support. Clear scope, defined responsibilities, no surprises.

Business

Growing organisations requiring stronger security, collaboration governance, structured change, and regular service reviews. The most common starting point for mid-market organisations.

Enterprise

Larger or regulated environments needing co-managed operations, detailed reporting, higher governance maturity, and broader Microsoft platform alignment.

Frequently asked questions

Eight common questions about how Harrby's managed Microsoft 365 service works in practice.

We work with smaller teams through to larger enterprise and government environments. Governance structures and scope are adjusted to match your operational needs and risk profile.

Yes. Many customers use a co-managed model where internal teams retain selected responsibilities. Role boundaries are documented and agreed upfront so both teams know exactly who owns what.

This service focuses on M365 workloads. Harrby also provides managed services across Azure, security, infrastructure, endpoints, and compliance. Many customers start with M365 and expand scope over time.

We can support both. Some customers retain licensing procurement elsewhere; others prefer a broader relationship. We work with either arrangement.

A structured change process with documented approvals for higher-risk changes. Routine changes follow a standard process. Significant changes are assessed, documented, and approved before implementation.

Essential Eight, ISO 27001, the ISM, and Microsoft Secure Score. Technical implementation support is provided. Regulatory or legal advice is out of scope.

Tenant review, then priorities, uplift, documentation, and transition into steady-state operations. Most customers are in managed operations within four to eight weeks.

Harrby tracks roadmap updates, Message Centre, and platform changes continuously. We assess impact on your environment and advise on changes that require action.

Start with a Microsoft 365 service review

A structured review of your current Microsoft 365 environment covering identity, messaging, collaboration, security, governance, and support patterns.

This review identifies immediate risks, governance gaps, support pain points, and service improvement opportunities. It also defines the right managed service scope and operating model for your organisation before any commitment is made.

What the review covers

The review covers identity health, email security, collaboration governance, security baseline, and operational gaps. It gives you a clear picture of where your environment stands before any commitment is made.

  1. Identity and access health: Entra ID, MFA, conditional access
  2. Email security posture: anti-phishing, impersonation controls
  3. Collaboration governance: Teams, SharePoint, OneDrive, guests
  4. Security baseline and configuration quality
  5. Support model and operational ownership gaps
  6. Recommended priorities and engagement approach
