The Microsoft 365 Challenge in Local Government Reorganisation
Microsoft 365 is likely to sit at the centre of most Local Government Reorganisation programmes.
It is where staff communicate, collaborate, store files, manage meetings, access applications, share information and increasingly interact with automation and AI-enabled tools. But during LGR, Microsoft 365 can also become one of the most complex areas to manage. A new authority may inherit multiple tenants, different identity configurations, inconsistent security controls, duplicated licensing, unmanaged Teams environments, separate SharePoint structures and different approaches to retention, compliance and external sharing. The LGA has highlighted that strong digital, data and technology planning supports seamless Day One services, a unified digital environment and modern, reliable ways of working for the new authority. Microsoft 365 is a key part of that digital environment.
Why Microsoft 365 Matters in LGR
Microsoft 365 is not just an email and productivity platform.
For councils, it can include:
- Exchange Online
- Teams
- SharePoint Online
- OneDrive
- Entra ID
- Intune
- Defender
- Purview
- Power Platform
- Windows 365
- Copilot readiness foundations
These services are deeply connected to how people work.
That means Microsoft 365 decisions affect:
- User experience
- Security
- Collaboration
- Records management
- Data protection
- Device management
- External sharing
- Licensing cost
- Service desk demand
- Long-term transformation
A rushed decision can create years of avoidable complexity.
A well-planned approach can provide the new authority with a secure, scalable and modern digital workplace.
The Tenant Strategy Question
One of the biggest questions in LGR is tenant strategy.
Councils may need to decide whether to:
- Retain one existing tenant as the future platform
- Create a new tenant for the new authority
- Operate multiple tenants during transition
- Use cross-tenant collaboration for a defined period
- Migrate users and data in phases
There is no single answer that works for every authority.
The right approach depends on:
- Scale and timing
- Existing tenant maturity
- Security posture
- Data volumes
- Records and retention requirements
- Domain strategy
- Branding and identity requirements
- Application dependencies
- Internal capability
- Programme risk tolerance
The key is to treat tenant strategy as a business and governance decision, not just a technical architecture choice.
Identity Comes First
Before users can collaborate effectively, identity needs to be understood.
Councils need to assess:
- How many identity platforms exist
- Whether Entra ID is consistently configured
- Whether MFA is fully enforced
- Whether Conditional Access policies are aligned
- Whether privileged access is properly governed
- How guest access is managed
- How identities map to legacy applications
- How joiner, mover and leaver processes will operate
The LGA’s LGR digital, data and technology guidance identifies cyber resilience, MFA, privileged access controls, patching and tested incident response as important considerations for predecessor councils.
Teams and SharePoint Need Governance
Teams and SharePoint are often where LGR becomes visible to staff.
They are also areas where sprawl can quickly develop.
Without governance, councils can end up with:
- Duplicated Teams
- Unclear ownership
- Inconsistent naming conventions
- Uncontrolled guest access
- Poor information architecture
- Unclear records ownership
- Excessive sharing
- Confusing document locations
- Increased service desk demand
A good LGR Microsoft 365 strategy should define:
- Team creation rules
- Naming standards
- Ownership responsibilities
- Guest access policy
- External sharing controls
- Information architecture
- Retention and sensitivity requirements
- Migration principles
- Archive approach
- Support model
This is especially important where predecessor councils are collaborating before legal vesting or while legacy environments remain active.
Endpoint Management and Intune
Microsoft 365 strategy should also connect to endpoint management.
Councils preparing for LGR should understand:
- Which devices are currently managed
- Whether Intune is in use
- Whether devices are compliant
- Whether Windows versions are supported
- Whether security baselines are consistent
- Whether applications are packaged and deployable
- Whether local administrator rights are controlled
- Whether Defender is correctly configured
- Whether devices can be rebuilt or redeployed at scale
A common endpoint strategy helps the new authority improve security, reduce support complexity and provide a more consistent user experience.
Purview, Retention and Compliance
LGR also raises important information governance questions.
Councils need to consider:
- What data must be retained
- Which retention policies apply
- Whether sensitivity labels are in use
- Whether records need to remain with predecessor councils
- How legal hold and audit requirements are handled
- How subject access requests will be supported
- How information will be discovered post-transition
- How external sharing is reviewed
This is one of the reasons Microsoft 365 migration should not be treated as a simple file movement exercise.
It is a governance, compliance and risk decision.
Copilot Readiness
Many councils will also be considering Microsoft Copilot as part of their longer-term digital workplace strategy.
LGR creates an opportunity to prepare the environment properly before AI tooling is widely introduced.
That means focusing on:
- Identity hygiene
- Data governance
- SharePoint permissions
- Sensitivity labels
- Retention policies
- Device security
- User adoption
- Change management
- Training
- Information architecture
If the new authority wants to benefit from AI in the future, it needs strong foundations now.
