Apps, capacities, mailbox size, eligible population, and the migration math that pulls field workers off E3 and captures meaningful savings.
Microsoft 365 F1 and F3 are the frontline plans. F1 lists at $2.25 per user per month. F3 lists at $8.00. The right population on these plans rather than on E3 typically saves $28 to $34 per user per month, which on a 10,000 frontline workforce becomes $3.4M to $4.1M per year.
This guide is the buyer side reference for the F1 vs F3 decision and the migration off E3. Read the related Microsoft practice, the M365 cost per user article, the license optimizer, and the EA renewal guide.
Microsoft defines frontline workers as shift workers, deskless workers, kiosk workers, and field service workers. The definition is narrower than many enterprise interpretations. The Microsoft Product Terms describe the eligibility test in writing.
Microsoft can challenge frontline classification at audit. The auditor reads role definitions, device assignments, and login patterns. The buyer side defense is documented eligibility evidence stored alongside the license register. The same evidence becomes the right size renewal argument.
F1 is the entry frontline plan. F1 provides identity and basic productivity. F1 does not include a mailbox, does not include the Office web apps in writable mode, and does not include Teams meeting recording.
F1 fits the kiosk worker, the shared device population, and the worker who only needs identity and basic communications. Retail floor staff using a shared tablet, warehouse staff signing on briefly to confirm shifts, and information kiosks all fit the F1 profile.
F3 is the productive frontline plan. F3 adds a 2GB mailbox, web Office in writable mode, basic Power BI, and meeting recording. F3 is appropriate for frontline workers who need light productivity.
F3 fits the frontline worker who needs an individual mailbox, occasional document creation in web Office, and full Teams meetings. Field service technicians, retail managers, store leads, and shift supervisors typically fit F3.
The side by side comparison shows the dollar gap and the capability gap. The E3 column is included because most enterprise frontline workforces sit on E3 by default.
| Capability | F1 ($2.25) | F3 ($8.00) | E3 ($36.00) |
|---|---|---|---|
| Identity (Entra ID) | Yes | Yes | Yes Premium |
| Mailbox size | None | 2GB | 100GB |
| Desktop Office apps | No | No | Yes |
| Web Office apps | Read mostly | Writable | Writable |
| Teams | Basic | Full | Full |
| OneDrive storage | 2GB | 2GB | 1TB |
| SharePoint | Limited | Standard | Standard |
| Power BI | No | Limited | Add on |
| Defender for Office | No | No | Add on |
| Yammer / Viva Connections | Yes | Yes | Yes |
The right tier is a function of the role, the device, and the communication pattern. The framework below assigns the right population to each tier with a defensible rationale.
| Population | Right tier | Why |
|---|---|---|
| Retail floor staff (shared device) | F1 | Kiosk and identity only |
| Retail manager | F3 | Mailbox plus light productivity |
| Warehouse picker | F1 | Shift confirmation only |
| Warehouse supervisor | F3 | Mailbox and reporting |
| Manufacturing operator | F1 | Identity and chat only |
| Shift lead / line supervisor | F3 | Mailbox and meetings |
| Field service technician | F3 | Light Office plus dispatch |
| Field engineer | F3 or E3 | Heavy Office tips toward E3 |
| Salaried knowledge worker | E3 | Full productivity and desktop apps |
Most enterprise frontline workforces sit on E3 by default because no one ever ran the right size exercise. The migration from E3 to F1 or F3 is the single most reliable cost lever in M365 licensing.
A frontline migration completed before the EA renewal cycle resets the renewal anchor to a right sized estate. The right sized estate is worth 6 to 12 percent in renewal discount uplift on top of the per user saving from the migration itself.
The eight step checklist below moves an enterprise from a frontline workforce sitting on E3 to a right sized F1 and F3 estate.
The list price gap is $28 per user per month, which is $336 per user per year. Net of typical EA discount, the saving is between $260 and $300 per user per year. On a 10,000 frontline workforce, the saving is between $2.6M and $3.0M per year, plus the renewal anchor uplift on the right sized estate.
No. Microsoft Product Terms restrict frontline licensing to shift workers, deskless workers, kiosk workers, and field service workers. The eligibility test in this guide describes the standard. Microsoft can challenge frontline classification at audit. The buyer side defense is documented eligibility evidence per user.
Most enterprise license rosters were built when E3 was the only enterprise plan. The frontline plans launched as F1 and F3 separately and the population on them grew slowly. Many IT licensing teams never ran the right size exercise. The migration is the most reliable cost lever, and it stays available year after year.
No. F3 includes the Office web apps in writable mode but not the desktop install. Frontline workers who need desktop Office must be licensed on E3 or buy the desktop add on. Most frontline roles do not require desktop Office because the work pattern is light document creation or read only.
The migration resets the EA renewal anchor to a right sized estate. The right sized estate is worth 6 to 12 percent additional discount uplift on top of the per user saving from the migration itself. The migration is most effective when completed 60 to 120 days ahead of the EA renewal window.
Assigning F3 to every frontline worker by default. F1 is the right tier for kiosk and shared device populations. The dollar difference between F1 and F3 is $5.75 per user per month, which compounds across large frontline workforces. The right populations for each tier are described in this guide.
