Microsoft 365 E3 license cost typically ranges based on region, licensing model, and add-ons, rather than a fixed global price. The total cost depends on factors like Teams (now sold separately), security upgrades, and additional services.
Microsoft 365 E3 is a widely used enterprise plan that includes productivity apps, security, compliance, and device management in one subscription. However, with recent licensing changes such as Teams unbundling and evolving add-ons it’s important to understand the full cost structure before purchasing.
This guide breaks down Microsoft E3 pricing, what’s included, what’s not, and how to calculate the real total cost in 2026.
Microsoft 365 E3 License Cost Overview
Microsoft 365 E3 pricing is not fixed globally and should not be considered a single standard number. The actual license cost depends on multiple factors, including:
- Region (e.g., India vs global markets)
- Licensing model (CSP, Enterprise Agreement, or direct purchase under Microsoft Customer Agreement (MCA))
- Volume of users and contract terms
- Inclusion or exclusion of Microsoft Teams
- Currency fluctuations and applicable taxes
Important 2026 Update: Teams Unbundling
For all new customers globally, Microsoft Teams is now unbundled by default. This means:
- Most organizations purchase Microsoft 365 E3 (without Teams)
- Microsoft Teams is added separately as Microsoft Teams Enterprise (SKU)
This is no longer optional—it is the standard commercial model.
Detailed Cost Breakdown of Microsoft 365 E3 License
When evaluating Microsoft E3 licensing, it is important to understand that the base license cost is only part of the total investment.
Core Cost Components
1. Cloud Services & Desktop Apps
Covers access to Office desktop apps, web apps, and cloud services.
2. Cloud Infrastructure
Includes Exchange Online, SharePoint, and OneDrive storage and services.
3. Security & Identity Licensing
Enables access to Microsoft Entra ID, Defender capabilities, and access controls.
4. Device & OS Licensing
Includes Windows Enterprise rights and Microsoft Intune for device management.
Real-World Cost Insight
In most enterprise environments:
- The base Microsoft E3 license represents only part of total cost
- Add-ons (security, AI, voice, analytics) significantly increase spend
- Third-party tools are often eliminated, offsetting E3 pricing
This makes it essential to evaluate Total Cost of Ownership (TCO) rather than just base license pricing.

What is Not Included in Microsoft 365 E3 License

Licensing Options and Flexibility

Key Considerations:
- Annual commitment is common
- Monthly billing may be available
- Flexible scaling based on workforce
- Upgrade path to E5 or add-ons
Example Microsoft E3 Licensing Scenario
For a mid-sized organization:
- Base Microsoft 365 E3 (without Teams): Core licensing provides access to productivity apps, cloud services, and essential security features for all employees.
- Teams Enterprise added separately: Organizations can purchase Microsoft Teams as a standalone add-on to align with updated licensing structure and collaboration needs.
- Security add-ons for IT/admin users: Advanced security tools can be assigned specifically to IT or high-risk roles to strengthen protection without increasing overall costs.
- Copilot for selected departments: AI-powered Copilot licenses can be deployed to specific teams like sales or marketing to enhance productivity where it delivers the most value.
Final cost becomes significantly higher than base license depending on adoption.
Who Should Choose Microsoft 365 E3 License
- Large or scaling organizations: Ideal for growing businesses that need a scalable, enterprise-grade solution to manage users, data, and collaboration efficiently as operations expand.
- Businesses needing desktop apps + cloud services: Best suited for companies that rely on fully installed Office apps like Word, Excel, and Outlook along with cloud-based tools such as Teams and OneDrive for seamless productivity.
- Companies managing multiple devices: Perfect for organizations that need centralized control and security across multiple user devices, including laptops, desktops, and mobile devices.
- Enterprises requiring moderate security with upgrade flexibility: Suitable for businesses that need built-in security and compliance features, with the option to enhance protection further through add-ons as requirements evolve.
When to Consider Upgrading Licensing
