Microsoft 365 is one of the largest recurring IT investments for most companies. It powers the modern workplace with collaboration in Teams, productivity through Office apps, and the security layers that keep information safe. But it is also an area where complexity leads to overspending and unused features.
Many organizations license everyone on the same plan without asking whether it reflects how people actually work. Executives are placed on premium licenses they do not fully use, frontline employees are given tools they rarely open, and IT continues to pay for overlapping third-party solutions that Microsoft 365 already includes.
The reality is that Microsoft 365 was designed with flexibility. There are enterprise plans, business plans, frontline options, and targeted add-ons. The right combination can reduce costs by double digits while strengthening security and simplifying operations. This guide will help you understand the main license families, where they are best applied, and how to build a mix that fits your workforce.
Enterprise Plans: E3, E5, and F3
For larger organizations, the enterprise plans are the backbone of Microsoft 365.
- E3 is the standard license for knowledge workers. It includes the full Office suite, Exchange email, SharePoint, Teams, and baseline security features. For most staff this is sufficient.
- E5 builds on E3 by adding advanced security, compliance, analytics, and voice. It unlocks tools like Microsoft Defender for Endpoint, Purview’s advanced eDiscovery and information governance, Power BI Pro, and Teams Phone. It is the most comprehensive plan but also the most expensive. In practice it is best reserved for specific groups such as executives, legal teams, or high-risk data roles.
- F3 is designed for frontline staff who use shared or mobile devices. It provides access to Office web and mobile apps and Teams, without the full desktop suite. This license can create significant savings in industries with large frontline populations such as retail or manufacturing
Business Plans: Premium, Standard, and Apps for Enterprise
Small and mid-sized businesses often look to the Business family of licenses.
- Business Premium is the most complete option. It includes Office apps, Teams, Exchange, SharePoint, Intune for device management, and Microsoft Defender for Business. For many SMBs it is attractive because it consolidates multiple third-party tools into one license.
- Business Standard provides the same collaboration and productivity tools but without the advanced security features of Premium. For companies just starting with Microsoft 365 this can be a good entry point.
- Apps for Enterprise provides the Office desktop apps only. It is a fit for contractors or part-time staff who need Word, Excel, and PowerPoint but use other platforms for communication and email.
Add-ons and Identity Controls
Not every scenario requires a full E5 license. Microsoft separates out advanced capabilities into add-ons that can be layered on top of E3 or Business Premium.
- The E5 Security add-on includes advanced threat protection such as Defender for Endpoint P2, Defender for Office 365 Plan 2, and identity protection features.
- The E5 Compliance add-on delivers advanced eDiscovery, records management, and communication compliance. It is especially relevant for organizations in regulated industries.
- For identity and access management, Entra ID P1 provides Conditional Access and basic governance while Entra ID P2 adds Privileged Identity Management and risk-based access controls. Most companies use P1 broadly and reserve P2 for admins or sensitive roles.
Building the Right Mix
The goal is not to put everyone on the same license. The goal is to align entitlements with roles.
Knowledge workers usually sit on E3 or Business Premium. Executives, legal teams, and high-risk users may need E5 or E3 with targeted add-ons. Frontline staff can be well served with F3. Contractors or part-time employees may only need Apps for Enterprise.
The mix should be reviewed regularly. Quarterly reviews tied to hiring cycles, seasonality, or project changes prevent waste and ensure governance stays aligned. Many organizations embed license optimization into their broader cloud cost practices, similar to the approach outlined in our FinOps Adoption consulting service.
Renewal Preparation
The biggest opportunity for savings comes at renewal. Companies that arrive with clear usage data and a role-based licensing plan can negotiate from a position of strength.
Preparation should include a headcount forecast, usage data that proves where premium features are needed, a plan to reclaim unused licenses, and a roadmap for consolidating third-party tools where Microsoft 365 already provides coverage.
By linking license decisions with other initiatives such as Zero Trust security enablement or End-User Virtualization on Azure, companies ensure that cost savings do not undermine security or employee experience.
