Introduction

Microsoft offers multiple licensing models for AI experiences across Microsoft 365. Understanding these licensing options is important for administrators who plan deployments, manage costs, and determine which AI capabilities are available to users.

For the AB-900 exam, you should understand the differences between:

  • Microsoft 365 Copilot monthly user licensing
  • Pay-as-you-go (consumption-based) licensing
  • SharePoint Copilot licensing
  • When each licensing model is appropriate

The exam focuses on understanding the concepts rather than memorizing pricing.

Why Multiple Licensing Models Exist

Organizations vary greatly in how employees use AI.

Some organizations:

  • Have employees who use AI all day.
  • Need AI integrated into Microsoft 365 apps.
  • Require predictable monthly costs.

Other organizations:

  • Use AI occasionally.
  • Need specialized agents.
  • Want to pay only when AI is used.

Microsoft therefore offers both subscription-based and consumption-based licensing.

Microsoft 365 Copilot Monthly License Model

The traditional Microsoft 365 Copilot license is assigned to individual users.

Each licensed user receives access to Copilot experiences across supported Microsoft 365 applications.

Examples include:

  • Word
  • Excel
  • PowerPoint
  • Outlook
  • Teams
  • OneNote
  • Microsoft 365 Chat

The license is:

  • Assigned per user
  • Monthly subscription
  • Predictable recurring cost

Characteristics of the Monthly License

The monthly model provides:

  • Full Microsoft 365 Copilot experience
  • Unlimited daily usage (subject to service limits)
  • Personalized AI assistance
  • Microsoft Graph integration
  • Cross-app experiences
  • Enterprise security and compliance

This model is best for employees who regularly use Copilot throughout their workday.

Typical Monthly License Scenario

A financial analyst uses Copilot every day to:

  • Analyze Excel workbooks
  • Draft reports
  • Summarize meetings
  • Create PowerPoint presentations
  • Search organizational knowledge

Because AI is used continuously, a monthly license provides predictable costs.

Benefits of Monthly Licensing

Advantages include:

  • Predictable budgeting
  • No need to monitor consumption
  • Continuous access
  • Simplified administration
  • Consistent user experience
  • Ideal for heavy users

Limitations of Monthly Licensing

Considerations include:

  • Fixed monthly cost regardless of usage
  • Not ideal for occasional users
  • Every user requires their own license
  • Organizations may over-license infrequent users

Pay-as-You-Go Licensing

Pay-as-you-go (PAYG) is a consumption-based licensing model.

Instead of paying for every user every month, organizations pay based on actual AI usage.

Think of it similarly to cloud computing services:

  • More usage = higher cost
  • Less usage = lower cost

Characteristics of Pay-as-You-Go

Pay-as-you-go provides:

  • Usage-based billing
  • Flexible scaling
  • No requirement for every user to have a monthly Copilot license
  • Cost based on AI requests or service consumption (depending on the service)

This model is especially useful for agents and certain AI scenarios.

Benefits of Pay-as-You-Go

Advantages include:

  • Lower upfront costs
  • Pay only for actual usage
  • Flexible deployment
  • Easy experimentation
  • Ideal for seasonal workloads
  • Good for occasional users

Limitations of Pay-as-You-Go

Potential drawbacks include:

  • Variable monthly costs
  • Budget forecasting is more difficult
  • Requires monitoring usage
  • Heavy usage may become more expensive than subscription licensing

Comparing Monthly Licensing and Pay-as-You-Go

Monthly LicensePay-as-You-Go
Fixed monthly costUsage-based cost
Licensed per userConsumption-based
Predictable budgetingVariable spending
Best for daily usersBest for occasional use
Continuous Copilot accessPay only when AI is used
Simpler cost managementRequires usage monitoring

Microsoft 365 Copilot Chat

Organizations should understand that Microsoft offers AI experiences beyond the traditional monthly Copilot license.

For example:

  • Microsoft 365 Copilot Chat is available to Microsoft 365 users.
  • Organizations can extend Copilot Chat with agents.
  • Some agent usage can be billed using pay-as-you-go licensing rather than requiring every user to have a full Copilot subscription.

This provides flexibility for organizations with mixed AI usage patterns.

SharePoint and Copilot

SharePoint includes AI capabilities that help users work with documents, sites, and organizational knowledge.

Examples include:

  • Summarizing documents
  • Answering questions about files
  • Generating page content
  • Assisting with document creation
  • Improving knowledge discovery

SharePoint Agents

One important capability is SharePoint agents.

A SharePoint agent can:

  • Be created from a SharePoint site or document library
  • Answer questions using approved SharePoint content
  • Help users locate organizational knowledge
  • Reduce the need to manually search documents

For example:

A Human Resources SharePoint site may contain:

  • Employee handbook
  • Benefits guide
  • Leave policies
  • Training documents

An HR SharePoint agent can answer employee questions using those documents.

SharePoint Pay-as-You-Go

Organizations can use SharePoint agents without assigning every user a full Microsoft 365 Copilot license.

Instead, administrators can configure consumption-based billing.

Benefits include:

  • Lower cost for occasional users
  • Easy pilot deployments
  • Department-specific AI
  • Flexible scaling

This makes SharePoint agents attractive for organizations wanting targeted AI experiences without licensing every employee.

Choosing the Right Licensing Model

Choose Monthly Licensing When

  • Employees use Copilot every day.
  • AI is integrated into daily workflows.
  • Predictable monthly budgeting is important.
  • Users need full Copilot functionality across Microsoft 365.

Examples:

  • Executives
  • Project managers
  • Analysts
  • Consultants
  • Sales professionals
  • Knowledge workers

Choose Pay-as-You-Go When

  • AI usage is occasional.
  • Organizations are testing AI.
  • Departments need specialized agents.
  • Seasonal usage is expected.
  • Budget flexibility is acceptable.

Examples:

  • HR help desk agent
  • Legal document agent
  • IT support chatbot
  • SharePoint knowledge assistant

Administrative Considerations

Administrators should evaluate:

  • Expected AI usage
  • Number of users
  • Cost predictability
  • Department requirements
  • Governance policies
  • Licensing strategy
  • Agent deployment plans

Security Remains the Same

Regardless of licensing model:

  • Microsoft Entra ID authentication is used.
  • Microsoft Graph permissions are enforced.
  • Microsoft Purview policies apply.
  • Data Loss Prevention (DLP) policies remain active.
  • Sensitivity labels continue protecting content.
  • Microsoft Defender protections remain in effect.

Licensing changes how organizations pay for AI—not how Microsoft secures organizational data.

Best Practices

Microsoft recommends that organizations:

  • License frequent users with Microsoft 365 Copilot subscriptions.
  • Use pay-as-you-go for occasional AI usage.
  • Monitor AI adoption and consumption.
  • Start with pilot deployments.
  • Evaluate SharePoint agents for departmental knowledge scenarios.
  • Review licensing regularly as adoption increases.

Exam Tips

For the AB-900 exam, remember these key points:

  • Microsoft 365 Copilot is commonly licensed per user with a monthly subscription.
  • Pay-as-you-go bills organizations based on AI usage.
  • Monthly licensing provides predictable costs.
  • Pay-as-you-go offers flexibility for occasional or specialized AI use.
  • SharePoint agents can be deployed using consumption-based licensing in supported scenarios.

  • Microsoft Graph, Microsoft Purview, and Microsoft Entra ID protections apply regardless of licensing model.
  • Heavy AI users are generally better suited to monthly licensing.
  • Departmental or pilot AI deployments often benefit from pay-as-you-go.
