Microsoft 365 in 2026: what it actually is today

Microsoft 365 has evolved significantly over the past few years. What was once seen primarily as email and Office software is now a platform that underpins:

• Identity and access management

• Device and endpoint security

• Data protection and compliance

• Collaboration and remote working

• Embedded AI and automation

In 2026, Microsoft 365 should be viewed less as a “licence” and more as core business infrastructure.

This shift is why licence choice matters more than it used to.

The main Microsoft 365 business licences (at a glance)

Most small and medium-sized businesses choose from the Microsoft 365 Business licence family. The main options are:

- Microsoft 365 Business Basic

- Microsoft 365 Business Standard

- Microsoft 365 Business Premium

- Microsoft 365 Apps for Business

These plans are designed for different ways of working. The right choice depends on whether users need business email, desktop Office apps, Teams, SharePoint, OneDrive, security features, device management or advanced protection.

Microsoft 365 Business plans are generally designed for organisations with up to 300 users. Larger organisations, or businesses with more complex compliance, identity, security or management requirements, may need to consider Microsoft 365 Enterprise plans such as E3 or E5.

Problems usually arise when licences are chosen based on price alone. A cheaper licence may look suitable at first, but it may not include the email, security, device management or compliance features the business needs.

It is also important to understand where Microsoft 365 Apps for Business fits. Apps for Business gives users the desktop Office apps and cloud storage, but it does not include business email hosting through Exchange Online. If your business needs Microsoft-hosted email, you will usually need Business Basic, Business Standard or Business Premium instead.

Some Microsoft 365 Business plans may be available in versions with or without Microsoft Teams, depending on region and Microsoft’s current licensing structure. If Teams is important to your business, check that the licence you choose includes it or that Teams is added separately.

What actually matters when choosing a Microsoft 365 licence

Before looking at individual licences, it’s important to understand the factors that should drive the decision.

In our experience, the right licence depends less on company size and more on:

• How sensitive your data is

• How your users access systems (office, remote, hybrid)

• Whether devices are company-managed or personal

• Your tolerance for security risk

• Your ability to monitor and respond to incidents

Licensing decisions should follow risk and operational reality, not just user count.

You may not need the same licence for every user

Many businesses do not need the same Microsoft 365 licence for every member of staff. A mixed licensing approach can reduce unnecessary spend by matching licence types to user roles, device needs, security requirements and whether each person needs desktop apps, email, Teams or advanced protection.

For example, some users may only need web-based apps and email, while others may need desktop Office apps, advanced security, device management or additional compliance features.

Licence breakdown (with context and remediation)

Microsoft 365 Business Basic

What it’s good for

• Cloud email and collaboration

• Lightweight access for frontline or occasional users

• Organisations with very limited device requirements

Where it falls short

• No desktop Office apps

• No device management

• Limited security controls by default

How businesses typically improve it To use Business Basic safely, organisations usually need to add:

• Strong identity controls (MFA enforcement)

• Third-party endpoint security

• Additional monitoring and policy controls

When it makes sense

• Very small teams

• Users who only need web access

• Environments with low data sensitivity

For most businesses, Business Basic is best used selectively, not as a standard licence.

Microsoft 365 Business Standard

What it’s good for

• Desktop Office apps

• Email and collaboration

• Familiar experience for most users

Where it falls short Business Standard is popular — but on its own, it provides limited identity and device security.

Out of the box, it lacks:

• Advanced identity protection

• Centralised device management

• Strong enforcement of security posture

How businesses typically improve it To secure a Business Standard environment, organisations often need:

• Enhanced identity controls

• Endpoint protection and device policies

• Better visibility over sign-ins and activity

Why this matters Without these controls, businesses may struggle to:

• Prevent account compromise

• Enforce consistent security across devices

• Respond quickly to suspicious behaviour

When upgrading makes sense In many cases, businesses find that Business Premium becomes more practical and cost-effective, as these security capabilities are included natively rather than bolted on separately.

Microsoft 365 Business Premium

What it’s good for Business Premium is often the better fit for businesses that need stronger security, device management and identity controls. However, the right licence depends on the user’s role, device use, risk level and security requirements.

It includes:

• Entra ID features for stronger identity control

• Device management and policy enforcement

• Improved visibility and access control

Why it’s commonly recommended For most SMEs, Business Premium provides:

• A good balance of cost and capability

• Built-in controls for modern working

• A foundation for security and compliance

Where it may fall short

• Limited advanced threat hunting

• Less suited to highly regulated environments

• Requires correct configuration to deliver value

Our typical recommendation For many SMEs, Business Premium is the minimum baseline we recommend, provided it’s properly configured and actively managed.

Microsoft 365 Enterprise (E3 / E5)

What they’re designed for Enterprise licences are built for organisations with:

• Complex compliance requirements

• Larger user bases

• Dedicated internal IT or security teams

E3 typically focuses on

• Advanced compliance and data governance

E5 adds

• Advanced security analytics

• Threat detection and investigation

• Greater visibility across the environment

Where caution is needed Enterprise licences are powerful — but expensive.

We often see organisations paying for E5 features they:

• Don’t use

• Don’t configure

• Don’t have the resources to manage

Enterprise licensing makes sense when the operational maturity is there to support it.

Recommendations by business type (general guidance)

These are guidelines, not rules — context always matters.

Common Microsoft 365 mistakes businesses make

• Choosing licences purely on cost

• Assuming security is “on by default”

• Mixing licences without a plan

• Ignoring device and identity management

• Treating Microsoft 365 as a set-and-forget service

Most issues arise not from Microsoft 365 itself, but from misalignment between licensing and reality.
