Microsoft 365 licensing is the single largest enterprise software line item in most large organizations. The licensing model combines plan SKUs, add on SKUs, Copilot, and channel choice. Each layer carries commercial implications worth modeling.
The pillar below maps every layer to the buyer side decision framework. Read the related Microsoft practice, the 2025 to 2026 licensing guide, the Copilot licensing article, the F1 vs F3 frontline guide, the EA vs MCA E comparison, the M365 reclamation guide, and the Microsoft knowledge hub.
The Microsoft 365 plan portfolio runs from the lightest frontline SKU through to the full security and compliance enterprise SKU. The map below shows the four core plans and the qualifying Business SKUs.
| Plan | Best for | 2025 list (USD/u/m) |
|---|---|---|
| M365 F1 | Kiosk and shared device, identity only | 2.40 |
| M365 F3 | Frontline mobile worker, light Office | 8.70 |
| M365 E3 | Knowledge worker, full Office, basic security | 38.75 |
| M365 E5 | Security premium, compliance, analytics | 60.50 |
| M365 Business Basic | Sub 300 seat SMB, web Office | 7.20 |
| M365 Business Standard | Sub 300 seat SMB, full Office | 14.40 |
| M365 Business Premium | Sub 300 seat SMB, security premium | 26.40 |
The frontline decision splits between F1 (identity only) and F3 (light Office and mobile). The choice depends on the workload profile of the frontline worker.
The E3 versus E5 decision is the single largest commercial decision in M365 licensing. The premium is roughly 22 dollars per user per month. The decision should run against role mapping and security telemetry.
| Component | E3 | E5 |
|---|---|---|
| Identity | Entra ID P1 | Entra ID P2 (PIM, identity protection) |
| Email security | Defender for Office Plan 1 | Defender for Office Plan 2 |
| Endpoint security | Defender Plan 1 | Defender Plan 2 |
| Identity threat | None | Defender for Identity |
| SaaS security | None | Defender for Cloud Apps |
| Compliance | Purview Foundation | Purview Information Protection |
| Analytics | None | Power BI Pro |
| Audio conferencing | Add on | Included |
Most enterprises that license 100 percent E5 over license the security premium. Most enterprises that license 100 percent E3 under license the executive and privileged user population. The right mix typically lands at 20 to 60 percent E5, with the balance on E3, F3, and F1.
Microsoft 365 Copilot is the AI overlay across the M365 estate. The Copilot price is 30 dollars per user per month on top of a qualifying base SKU.
Six add ons drive the bulk of the commercial conversation beyond the core plan SKUs. Each add on carries telemetry data that should drive the renewal quantity.
| Add on | Purpose | 2025 list (USD/u/m) |
|---|---|---|
| Defender for Office 365 Plan 2 | Email security premium | 5.25 |
| Entra ID P2 | PIM, identity protection | 9.50 |
| Defender for Endpoint Plan 2 | Endpoint security premium | 5.50 |
| Purview Information Protection | Data classification, DLP | 7.00 |
| Power BI Pro | Self service analytics | 10.00 |
| Visio Plan 2 | Diagramming | 15.00 |
The three Microsoft commercial channels each fit a different profile in 2026. The channel decision sits alongside the plan and add on decisions.
| Channel | Best for | Trade off |
|---|---|---|
| EA | 500+ seats, held price legacy | 3 year commit, bulk True Up |
| MCA E | 500+ seats, EA succession | Direct Microsoft, no LSP |
| CSP | Partner heavy, sub 500 seats | Partner margin, month to month |
The eight step checklist below moves an M365 estate from drift to a documented buyer side baseline.
M365 E3 includes the Office apps, Teams, Exchange, SharePoint, OneDrive, Intune, Entra ID P1, and Defender for Office Plan 1. M365 E5 adds Entra ID P2, Defender for Office Plan 2, Defender for Endpoint Plan 2, Defender for Identity, Defender for Cloud Apps, Purview Information Protection, Power BI Pro, and audio conferencing. The price difference is roughly 22 dollars per user per month.
F1 and F3 are the frontline worker SKUs. F1 is identity and Teams only, for kiosk and shared device populations. F3 includes web Office, Teams, Exchange mailbox up to 2 GB, SharePoint, and basic Intune. F3 fits the mobile or shopfloor worker who needs collaboration but not desktop Office. F1 is 2.40 dollars per user per month. F3 is 8.70 dollars per user per month.
M365 Copilot is 30 dollars per user per month on top of a qualifying base SKU (E3, E5, or qualifying Business). Copilot is annual commit in EA and MCA E. CSP allows month to month. Volume discount escalates at 1,000, 5,000, and 10,000 seat tiers. Strategic transaction overlays unlock further discount when bundled at renewal.
Three channels are available. EA for 500+ seats with held price legacy. MCA E for 500+ seats migrating from EA or starting fresh. CSP for partner heavy ecosystems or sub 500 seat estates. Most 2026 renewals migrate from EA to MCA E. The right channel depends on volume, term, partner relationships, and the held price legacy.
Six add ons drive the commercial conversation. Defender for Office 365 Plan 2, Entra ID P2, Defender for Endpoint Plan 2, Purview Information Protection, Power BI Pro and Premium per user, and Visio Plan 2. Each carries telemetry data that should drive the renewal quantity. Programs that license add ons based on the M365 base typically over license by 18 to 32 percent.
Five practices deliver the best pricing. Pull held price across the EA cycle. Right size the mix between E3, E5, F1, and F3 against role mapping. Run Copilot against adoption telemetry, not M365 base. License add ons against workload telemetry. Build a credible alternative posture, especially in EEA where Teams unbundling opens new options.
Redress runs the M365 licensing workstream across the renewal cycle. The engagement maps the role mix to plans, pulls workload telemetry for add ons, sets the Copilot count against adoption data, and shapes the renewal envelope.

Open the Paper →Our M365 estate had drifted to 100 percent E5 and 100 percent Copilot. The buyer side reset moved 38 percent of users to E3, 12 percent of frontline workers to F3, and right sized Copilot to active use. The right sized estate cut M365 spend by 19 percent without losing a single workload.
