Conduct a License Usage Audit
Start with data. Determine which of your licenses are being utilised, which features are being used by your employees, and which accounts are inactive. Those licenses that are inactive or underutilized may be downgraded or reassigned. Microsoft's admin center, combined with third-party insights, can identify patterns that bring to uncover hidden waste.

License Rightsizing
License rightsizing is one of the most effective Microsoft 365 cost-control strategies. Many organizations assign the same license tier across departments, even though user requirements vary significantly. By aligning license plans with employee roles, usage patterns, and business needs, IT leaders can eliminate unnecessary spend while maintaining productivity.
For example, frontline employees may only require Microsoft 365 F3 licenses, while knowledge workers can operate effectively with E3. Advanced E5 licenses should be reserved for users who genuinely require enhanced security, compliance, analytics, or voice capabilities.
A structured license rightsizing strategy helps organizations improve budget efficiency, strengthen governance, and maximize Microsoft 365 ROI.

Right-Size Plans for User Groups
Not every user needs an E5 license. Segment your workforce by job function and license them accordingly:
- Frontline workers may only need F3 licences that grant them access to Teams, email, and mobile access.
- Knowledge workers might require E3 licenses that encompass productivity as well as collaboration tools.
- Executives and security/IT-sensitive roles could perhaps justify the advanced analytics and security of E5.
By right sizing, IT leaders prevent the "one-size-fits-all" trap that inflates costs.
Organizations that regularly review license allocations are better positioned to adapt to workforce changes, mergers, role transitions, and evolving business requirements. Rightsizing should be conducted quarterly to ensure licenses remain aligned with actual usage and business objectives.

Microsoft 365 E5 Cost Optimization
Microsoft 365 E5 provides advanced capabilities including Microsoft Defender, Microsoft Entra ID Premium, Power BI Pro, compliance tools, and advanced analytics. However, many organizations purchase E5 licenses for users who only utilize a fraction of these features.
To optimize Microsoft 365 E5 costs, IT leaders should:
- Identify users actively consuming E5-exclusive features.
- Downgrade users who only require E3 functionality.
- Evaluate standalone security or compliance add-ons versus full E5 licensing.
- Review utilization reports before license renewals.
- Implement governance policies for E5 assignment approvals.
A targeted E5 optimization strategy can significantly reduce licensing costs without compromising security, compliance, or user productivity.

Eliminate Redundant Third-Party Tools
Microsoft 365 includes advanced functionality: endpoint management, security, communication, and collaboration, often replace subscriptions. Auditing the stack causes overlapping tools, such as third-party chat, meeting, or security offerings, to be retired. That's not only reducing expenditure but also streamlining IT oversight.
-
Managing Underutilized M365 Seats
Underutilized Microsoft 365 seats are one of the most common sources of licensing waste. Employees who have left the organization, changed roles, or rarely access Microsoft 365 services often continue consuming paid licenses.
IT leaders should establish regular reviews to identify:
- Inactive user accounts
- Dormant Microsoft 365 subscriptions
- Duplicate license assignments
- Temporary project users with expired requirements
- Contractor accounts no longer in use
Recovering and reallocating underutilized M365 seats improves license efficiency and prevents unnecessary spending across the organization.
-
Maximise Microsoft Copilot Value
With Microsoft Copilot being licensed separately, IT leaders must pay close attention to ROI. Start by implementing pilot programs for high-value departments (sales, operations, customer support) to test productivity improvements. Expand licensing strategy, rather than rolling out enterprise-wide without metrics.

Partner with a Licensing Optimization Expert
Staying updated with the latest Microsoft licensing policy changes is a full-time job. Partnering with an experienced Microsoft Azure and Microsoft 365 solution provider like eprotech ensures that organisations have professional guidance on identifying potential cost savings, creating bespoke licensing scenarios, and implementing governance processes that foster ongoing optimisation well into the future.
