How to Properly License Your Users for Microsoft 365 in 2026

Microsoft 365 licensing is no longer just a choice between a few Office plans. In 2026, the right approach must account for New Commerce Experience purchasing rules, Teams packaging, Microsoft 365 Copilot readiness, security requirements, device management, and user lifecycle processes.

What Microsoft 365 includes today

Microsoft 365 combines productivity apps, cloud services, identity, security, compliance, device management, and—in some plans—Windows 11 upgrade rights for eligible devices. Depending on the subscription, it may include Microsoft 365 apps such as Word, Excel, PowerPoint, Outlook, and OneDrive; collaboration services such as Exchange Online, SharePoint, and Teams; security and management capabilities such as Microsoft Entra ID, Microsoft Intune, Microsoft Defender, and Microsoft Purview; and business or enterprise Windows rights.

The important point: Microsoft 365 is licensed primarily per user, but the services available to each user depend on the specific plan, add-ons, geography, and purchase channel.

Understand subscriptions, licenses, and service plans

A Microsoft 365 subscription is the commercial agreement for a product SKU, such as Microsoft 365 Business Premium or Microsoft 365 E3. A license is the seat assigned to a user from that subscription. A service plan is an individual workload or feature inside that license, such as Exchange Online, SharePoint, Intune, Defender, or Microsoft 365 apps.

Users need the appropriate license to use paid Microsoft 365 services. However, not every Microsoft Entra ID account needs a paid Microsoft 365 license simply to exist, sign in, act as an administrator, or participate as a guest. Licensing should be matched to what the user actually needs to do.

A single user can have multiple licenses, but overlapping licenses can create unnecessary cost. For example, assigning both Microsoft 365 Business Premium and a standalone Exchange Online plan to the same person may be redundant unless there is a specific reason.

Choose plans by user role, not by habit

Start by grouping users by role and workload requirements. Common examples include office workers, executives, frontline staff, field teams, contractors, shared-device users, administrators, and regulated users with advanced compliance needs.

Common plan families include:

• Microsoft 365 Business Basic: web and mobile productivity apps, email, cloud storage, and collaboration services for small and midsize businesses.
• Microsoft 365 Business Standard: Business Basic plus desktop Microsoft 365 apps.
• Microsoft 365 Business Premium: Business Standard plus stronger security and device management, including Intune, Microsoft Entra ID Premium capabilities, and Microsoft Defender for Business.
• Microsoft 365 Apps for business or enterprise: desktop apps without the full set of Microsoft 365 cloud services.
• Microsoft 365 E3: enterprise productivity, identity, management, and compliance foundation.
• Microsoft 365 E5: advanced security, compliance, analytics, and voice-related capabilities depending on SKU and region.
• Microsoft 365 F plans: frontline-worker options for users who need lighter productivity and collaboration capabilities.
• Education, nonprofit, and government plans: specialized licensing programs with different eligibility and availability rules.

For many organizations, the best design is a mix of plans: Business Premium or E3/E5 for knowledge workers, frontline plans for shift-based users, and carefully selected add-ons for specific needs.

Account for CSP and New Commerce Experience rules

Most Microsoft 365 commercial subscriptions purchased through Cloud Solution Provider partners are now managed under Microsoft’s New Commerce Experience (NCE). This affects how you buy, adjust, and renew licenses.

Key points to plan for:

• Monthly terms offer the most flexibility because seats can generally be reduced at the next monthly renewal, but they are typically priced higher than annual commitments.
• Annual terms usually provide better pricing stability, but seat reductions are generally limited after the short cancellation window and are normally handled at renewal.
• Billing frequency and commitment term are different concepts. An annual subscription may be billed monthly or upfront, depending on the offer.
• You can usually add seats during the term, but reducing seats after the cancellation window may not be allowed until renewal.
• New subscriptions and renewals have a limited cancellation or seat-reduction window; confirm the current timing before purchase or renewal.
• Co-terming can align subscription end dates, which simplifies renewals and budgeting.
• Trials, add-ons, self-service purchases, and partner-led subscriptions should be reviewed together so you do not create unmanaged licensing sprawl.

Because NCE rules can affect cost when employees leave or projects change, licensing should be reviewed before renewals—not after.

Do not overlook Microsoft Teams licensing

Teams packaging has changed in recent years. Whether Teams is included in a Microsoft 365 or Office 365 suite can depend on the plan, region, customer status, and SKU purchased. Some customers may have suites that include Teams, while others may need a separate Microsoft Teams license.

Also remember that Teams collaboration, Teams Phone, calling plans, Audio Conferencing, Teams Rooms, webinars, and advanced meeting features may require separate licenses or add-ons. Before standardizing on a plan, confirm exactly which Teams capabilities your users need.

Plan for Microsoft 365 Copilot and AI readiness

Microsoft 365 Copilot is licensed as an add-on to eligible base subscriptions. Eligibility and packaging can change, so confirm current requirements before purchase. Microsoft also offers Copilot Chat experiences for many work accounts, with additional licensing or consumption charges possible for some agent and automation scenarios.

Before assigning Copilot licenses, prepare your Microsoft 365 environment:

• Verify eligible base licenses and required apps.
• Review SharePoint, OneDrive, Teams, and mailbox permissions so users do not surface content they should not access.
• Implement sensitivity labels and data loss prevention where appropriate.
• Review Microsoft Purview retention and compliance requirements.
• Strengthen identity security with MFA, Conditional Access, and least-privilege admin roles.
• Create adoption guidance, prompt training, and business use cases.

Copilot licensing should be treated as both a productivity decision and a data governance decision.

Assign licenses at scale

For a small tenant, assigning licenses in the Microsoft 365 admin center may be enough. For larger organizations, use Microsoft Entra group-based licensing to assign licenses through security groups or dynamic groups. This reduces manual work and helps make onboarding and offboarding consistent.

Modern options include:

• Microsoft 365 admin center for direct license assignment and subscription management.
• Microsoft Entra group-based licensing for role-based assignment.
• Dynamic groups for automatic membership based on user attributes.
• HR-driven provisioning and lifecycle workflows where available.
• Microsoft Graph and modern PowerShell modules for automation.

Avoid relying on legacy Azure AD or MSOnline tooling for new automation projects. Build around Microsoft Entra ID and Microsoft Graph.

Handle leavers and data retention correctly

Removing a license is not the same as deleting a user, and retention behavior varies by workload. Exchange Online, OneDrive, SharePoint, Teams, and Purview all have different retention mechanics. Your process should be based on business, legal, and compliance requirements—not assumptions.

A practical leaver process usually includes:

• Block sign-in or revoke sessions when appropriate.
• Preserve mailbox data; convert to a shared mailbox if appropriate and licensed correctly.
• Transfer OneDrive ownership or access to a manager or records owner.
• Review Teams and SharePoint ownership so collaboration spaces are not orphaned.
• Apply or verify Microsoft Purview retention policies when required.
• Remove or reassign licenses only after data preservation steps are complete.
• Document exceptions for legal hold, compliance retention, or ongoing investigations.

Do not rely on a generic “30 days” rule for all Microsoft 365 data. Retention depends on the action taken, workload settings, and any Purview policies in place.

Optimize licenses continuously

Microsoft 365 licensing is not a one-time project. Review it regularly to control cost and reduce risk.

Look for:

• Unassigned licenses that are still being paid for.
• Inactive users with active licenses.
• Users with overlapping plans or duplicate add-ons.
• Premium features assigned to users who do not need them.
• Users who need stronger security, such as administrators without appropriate identity protection.
• Business units buying trials or self-service subscriptions outside governance.
• Upcoming NCE renewal dates and seat-reduction deadlines.

License optimization should be tied to security reviews, Microsoft Secure Score, compliance needs, and business changes.

Support adoption after licensing

The right license only creates value when users adopt the tools. Build an adoption plan for Microsoft 365 apps, Teams, OneDrive, SharePoint, security practices, and Copilot where applicable.

Useful adoption activities include:

• Role-based training for employees, managers, and administrators.
• Teams champions or departmental power users.
• Viva Learning or a centralized training portal for self-service learning.
• Clear guidance on when to use Teams, email, SharePoint, OneDrive, and Loop components.
• Copilot use-case workshops and prompt guidance.
• Post-deployment feedback loops and helpdesk readiness.
• Ongoing measurement using available Microsoft adoption and usage reports.

Adoption should continue after deployment so your licensing investment turns into measurable productivity and security improvements.

Key takeaways

• Microsoft 365 licensing should be designed by user role, workload, security requirement, and lifecycle process—not by assigning the same plan to everyone.
• CSP New Commerce Experience terms make renewal planning, seat reductions, cancellation windows, and co-terming important cost-control topics.
• Teams and Copilot licensing require extra attention because eligibility, packaging, add-ons, and regional availability can vary.
• Microsoft Entra group-based licensing, dynamic groups, and Microsoft Graph automation help keep license assignment consistent at scale.
• Removing a license does not automatically solve retention or offboarding; Exchange, OneDrive, SharePoint, Teams, and Purview policies must be reviewed together.
