This chapter covers Microsoft 365 Frontline Worker features, which are specifically designed for employees who primarily interact with customers or work on the front lines—retail associates, factory workers, healthcare staff, and field service technicians. For the MS-900 exam, understanding the differences between F1, F3, and other license types is critical, as questions about licensing scenarios appear frequently (approximately 10-15% of exam questions). You will learn what services are included, how they differ from enterprise plans, and how to choose the right license for different worker profiles.

Imagine a large construction company. The full-time project managers get a massive toolbox with every power tool, safety gear, and spare parts (Microsoft 365 E3/E5). But the majority of workers—carpenters, electricians, masons—only need a few specific tools to do their job: a hammer, a tape measure, a hard hat, and a basic phone to communicate with the foreman. Giving them the full toolbox would be wasteful and expensive. Instead, the company provides a 'Frontline Worker Toolbox' (F1/F3 licenses) that contains exactly those essential tools: a rugged smartphone for check-ins, a walkie-talkie app for instant messages, a schedule board, and a simple clock-in/clock-out system. The foreman (manager) uses a slightly better toolbox (F3) that also includes a tablet for viewing reports and approving time-off requests. The company saves money by not buying full toolboxes for workers who never need a table saw or a laser level. Similarly, Microsoft 365 Frontline Worker licenses are purposely limited to the apps and services that shift workers actually use—like Shifts, Tasks, and Approvals—while excluding advanced tools like Power BI, advanced eDiscovery, or full desktop Office. The licensing is enforced by Azure Active Directory: when a user is assigned an F1 or F3 license, Microsoft 365 checks the license SKU and only enables the corresponding service plans. If a frontline worker tries to access a blocked service (e.g., Power BI), they get an 'access denied' or 'license required' error. This mechanism ensures that organizations only pay for what their frontline workforce needs, reducing per-user cost by up to 70% compared to E3 licenses.
What Are Frontline Workers and Why Do They Need Special Licensing?
Frontline workers are employees whose primary role involves direct interaction with customers, patients, or physical tasks rather than desk-based knowledge work. They are often shift-based, use mobile devices, and need simple, focused tools for communication, scheduling, task management, and training. Microsoft estimates that 80% of the global workforce is deskless, yet many organizations historically licensed them with full E3/E5 suites—overpaying for unused features like advanced analytics, compliance, or full Office desktop apps.
Microsoft 365 Frontline Worker licenses (F1 and F3) are purpose-built to address this gap. They provide a subset of Microsoft 365 services tailored to frontline scenarios at a lower cost per user. The exam tests your ability to identify which license is appropriate based on job roles and required functionality.
How Frontline Worker Licenses Work Internally
Frontline Worker licenses are enforced via service plans within the Microsoft 365 tenant. Each license SKU (e.g., MICROSOFT 365 F1, MICROSOFT 365 F3) contains a specific set of service plans that Azure Active Directory evaluates during authentication and authorization. When a user signs in, Microsoft 365 checks the assigned license and determines which services the user can access. If a service plan is not included, the user sees an error message or the service is grayed out.
F1 License (SKU: M365_F1): - Includes: Exchange Online Kiosk (2 GB mailbox), Microsoft Teams (with Shifts, Tasks, Approvals, Walkie Talkie), SharePoint Online Kiosk, Viva Connections, Viva Learning, Microsoft 365 Apps for Business (web only), and mobile versions of Office apps. - Excludes: Desktop versions of Office, advanced compliance (e.g., eDiscovery, retention policies), Power BI Pro, Azure Information Protection, and enterprise-scale storage. - Price: Approximately $10/user/month (as of 2025).
F3 License (SKU: M365_F3): - Includes everything in F1 plus: Exchange Online (50 GB mailbox), Microsoft 365 Apps for Business (desktop apps on up to 5 devices), Power Apps and Power Automate for Microsoft 365, Microsoft Forms, and Microsoft Planner. - Excludes: Advanced compliance, eDiscovery, Power BI Pro, and enterprise voice features. - Price: Approximately $20/user/month.
Key Differences Between F1 and F3: - Desktop Office apps: F3 includes full desktop versions of Office (Word, Excel, PowerPoint, Outlook) on up to 5 devices per user; F1 only includes web and mobile versions. - Mailbox size: F3 gives 50 GB mailbox; F1 gives 2 GB (Kiosk). - Power Platform: F3 includes Power Apps and Power Automate capabilities for building custom apps and flows; F1 does not. - Microsoft Planner: F3 includes Planner for lightweight project management; F1 does not.
Microsoft Teams Features for Frontline Workers
Microsoft Teams is the central hub for frontline workers. The following features are specifically designed for and included in F1 and F3 licenses:
Shifts: A schedule management tool that allows managers to create, publish, and manage shifts. Workers can request time off, swap shifts, and clock in/out. Shifts data is stored in the Microsoft 365 tenant and can be integrated with third-party workforce management systems via Graph API.
Walkie Talkie: A push-to-talk (PTT) feature over IP that uses the device's microphone and speaker. It requires Wi-Fi or cellular data and supports up to 100 participants in a channel. Walkie Talkie is available on mobile devices (iOS/Android) and is included in both F1 and F3.
Tasks: Allows managers to assign tasks to individuals or groups. Tasks from Microsoft To Do, Planner, or third-party apps can be surfaced in Teams.
Approvals: Create and manage approval requests for time-off, expenses, or purchase orders directly within Teams.
Viva Connections: A personalized dashboard that aggregates news, resources, and tasks. It is available in F1 and F3 but with limited capabilities compared to E3/E5.
Viva Learning: Provides access to training content from Microsoft Learn and third-party providers. F1/F3 includes basic features; advanced analytics require E3/E5.
Configuration and Verification Commands
To verify which licenses are assigned to users, administrators can use the Microsoft 365 admin center or PowerShell. For example, to list all users with F1 licenses:
Get-MgUser -All | Where-Object {$_.AssignedLicenses.SkuId -contains '365a1e1b-2c3d-4e5f-6a7b-8c9d0e1f2a3b'}To check the service plans enabled for a user:
Get-MgUserLicenseDetail -UserId "user@contoso.com" | Select-Object -ExpandProperty ServicePlansIn the admin center, navigate to Billing > Licenses to see usage and assign licenses.
Interaction with Related Technologies
Azure Active Directory: License assignment is managed via Azure AD. Each user can have multiple licenses; service plans are aggregated. If a user has both F1 and an E3 license, the more permissive service plan takes precedence (e.g., desktop Office from E3 will be available).
Microsoft 365 Groups: Shifts, Tasks, and other frontline features rely on Microsoft 365 Groups. When a Shifts schedule is created, a corresponding group is created in Azure AD.
Intune: Mobile device management (MDM) and mobile application management (MAM) policies can be applied to frontline workers' devices. Both F1 and F3 include basic Intune capabilities for device management.
Power Platform: F3 users can build and use custom apps with Power Apps and automate workflows with Power Automate, but only within the limits of the Microsoft 365 service plans (no premium connectors).
Licensing Scenarios on the Exam
The MS-900 exam often presents scenarios where you must recommend the appropriate license. Common scenarios include:
A retail associate who only needs to check schedules, clock in/out, and use instant messaging on a company phone → F1.
A shift supervisor who needs to create schedules, approve time-off requests, and use desktop Office for reporting → F3.
A nurse who needs to access patient records in a custom Power App and use email with a larger mailbox → F3 (or even E3 if compliance requirements exist).
A warehouse worker who only uses a shared computer for clocking in → F1 (or even a free Azure AD account if no Microsoft services are needed).
Important Exam Values and Defaults
F1 mailbox size: 2 GB (Exchange Online Kiosk).
F3 mailbox size: 50 GB (Exchange Online Plan 1).
F1 does NOT include desktop Office apps; F3 includes Office 365 for Business (desktop) on up to 5 devices.
F1 includes Teams with Shifts, Walkie Talkie, Tasks, Approvals, Viva Connections, Viva Learning.
F3 includes everything in F1 plus Planner, Power Apps, Power Automate, and Microsoft Forms.
Neither F1 nor F3 includes Power BI Pro, Advanced Compliance (eDiscovery, retention), or Azure Information Protection P2.
Both F1 and F3 include Microsoft 365 Defender for Office 365 (basic) and Azure AD P1.
Price difference: F1 ~$10, F3 ~$20, E3 ~$36, E5 ~$57 per user/month (list prices).
Identify Worker Profile
First, determine if the worker is a frontline employee. Frontline workers are typically shift-based, use mobile devices, and do not have a dedicated desk. They need basic communication, scheduling, and task management tools. Examples: retail associates, factory workers, nurses, field service technicians. If the worker needs advanced compliance, full desktop Office, or Power BI, they are not a pure frontline worker and may need E3/E5.
Assess Required Services
List the specific Microsoft 365 services the worker needs. For example: does the worker need a large mailbox? If yes, F1 (2 GB) may be insufficient → consider F3 or E3. Does the worker need desktop Office apps? F1 only provides web/mobile; F3 provides desktop apps. Does the worker need Power Apps or Power Automate? F3 includes these; F1 does not. Does the worker need Shifts, Walkie Talkie, Tasks? Both F1 and F3 include these.
Compare License Options
Based on the required services, compare F1, F3, and possibly E3/E5. F1 is the lowest cost (~$10/user/month) but has the most limitations. F3 (~$20) adds desktop Office, larger mailbox, and Power Platform. E3 (~$36) adds full compliance, eDiscovery, and larger storage. E5 (~$57) adds advanced security and analytics. For the exam, remember that F1 and F3 are specifically designed for frontline workers and exclude certain enterprise features.
Assign License via Admin Center
In the Microsoft 365 admin center, navigate to Users > Active Users. Select the user(s), then click Licenses and Apps. Choose the appropriate license (e.g., Microsoft 365 F1 or F3). Ensure the correct service plans are enabled. You can also use PowerShell or Azure AD to assign licenses. After assignment, the user can access enabled services within minutes.
Verify Access and Functionality
After license assignment, verify that the user can access the required services. For example, sign in as the user and check that Teams shows Shifts, Walkie Talkie, and Tasks. If the user needs desktop Office, confirm they can install and activate Office apps. If a service is missing, check that the corresponding service plan is enabled in the license. Use the Microsoft 365 admin center or PowerShell to review service plans.
Enterprise Scenario 1: Retail Chain with 10,000 Store Associates
A national retail chain with 10,000 store associates needed a communication and scheduling solution. Associates primarily used company-provided iPhones to check schedules, clock in/out, receive announcements, and message managers. They did not need email or desktop Office. The company initially considered E3 licenses but realized they would pay $360,000/month vs. $100,000/month with F1. They deployed F1 licenses with Teams, Shifts, and Walkie Talkie. Managers used F3 licenses to create schedules and approve time-off. The rollout used Intune to manage the devices and enforce MAM policies to prevent data leakage. One challenge: associates with shared devices needed to sign in each shift; using Kiosk mode on the devices reduced sign-in friction. The company saved $3.12 million annually in licensing costs.
Enterprise Scenario 2: Hospital System with Nurses and Doctors
A large hospital system had 5,000 nurses and 2,000 doctors. Nurses needed to view schedules, communicate securely via Teams, and access a custom Power App for patient checklists. Doctors needed full desktop Office, email with large mailboxes, and compliance features for patient data. The hospital assigned F3 licenses to nurses ($20/user/month) because they needed Power Apps and a 50 GB mailbox for email notifications. Doctors received E5 licenses for advanced compliance (e.g., eDiscovery for medical records) and Power BI Pro for analytics. The hospital used Azure AD Conditional Access to require multi-factor authentication for all frontline workers. A mistake: initially, they assigned F1 to nurses, but the 2 GB mailbox filled quickly with system-generated emails, causing delivery failures. Upgrading to F3 resolved the issue.
Common Misconfigurations
Over-licensing: Assigning E3/E5 to all frontline workers wastes budget. Always start with F1/F3 and upgrade only if needed.
Under-licensing: Assigning F1 to a supervisor who needs desktop Office or Power Apps leads to user complaints and productivity loss.
Service plan misalignment: Even with the correct license, some service plans may be disabled by default (e.g., Viva Learning). Administrators must verify that required plans are enabled in the license settings.
Device management: F1/F3 include basic Intune, but if advanced device compliance policies are needed, an additional Intune license may be required.
What MS-900 Tests on Frontline Worker Features (Objective 4.1)
The exam expects you to:
Identify the characteristics of frontline workers.
Compare F1, F3, and other Microsoft 365 licenses based on included services.
Recommend the appropriate license for given scenarios.
Understand which services are included/excluded in each license.
Common Wrong Answers and Why Candidates Choose Them
Choosing E3 for a retail associate – Candidates see 'email' and 'Office' and assume everyone needs them. But the question explicitly states 'no need for desktop Office' or 'only needs mobile access'. F1 is sufficient.
Choosing F1 for a supervisor who needs to create schedules – Candidates think F1 includes Shifts (true) but forget that creating schedules requires desktop Office or additional features. Actually, Shifts management is available in both F1 and F3, but if the supervisor needs to run reports in Excel, they need desktop Office → F3.
Thinking F3 includes Power BI Pro – F3 does NOT include Power BI Pro. Power BI Pro is only in E5 or as an add-on. Candidates often confuse Power Apps with Power BI.
Assuming F1 includes desktop Office – F1 includes only web and mobile versions. Desktop Office is only in F3 and above.
Specific Numbers and Terms That Appear on the Exam
F1 mailbox size: 2 GB (Exchange Online Kiosk).
F3 mailbox size: 50 GB (Exchange Online Plan 1).
F1 price: ~$10/user/month.
F3 price: ~$20/user/month.
F1 includes: Teams, Shifts, Walkie Talkie, Tasks, Approvals, Viva Connections, Viva Learning.
F3 adds: Desktop Office, Power Apps, Power Automate, Planner, Forms, 50 GB mailbox.
Neither F1 nor F3 includes: Power BI Pro, Advanced Compliance, Azure Information Protection P2, Enterprise Voice.
Edge Cases and Exceptions
Shared devices: Frontline workers often use shared devices. F1/F3 licenses are per-user, not per-device. Multiple users can sign in on the same device, but each needs a license.
Free licenses: Azure AD Free tier allows basic sign-in but no Microsoft 365 services. For workers who only need to clock in via a third-party app, a free account might suffice, but the exam expects you to recommend F1 for any Microsoft service usage.
Add-ons: Some features like Power BI Pro or Advanced Compliance can be added to F1/F3 as separate licenses, but the exam typically tests the base license capabilities.
How to Eliminate Wrong Answers Using the Underlying Mechanism
When you see a scenario, map each requirement to a specific service plan. For example: - 'Needs to send and receive email' → requires Exchange Online. F1 has Kiosk (2 GB), F3 has Plan 1 (50 GB). If the scenario mentions 'large attachments' or 'archive', F1 is insufficient. - 'Needs to create and edit documents offline' → requires desktop Office → F3 or higher. - 'Needs to view schedules and clock in' → only needs Teams and Shifts → F1 is enough. - 'Needs to build custom forms and automate workflows' → requires Power Apps and Power Automate → F3.
By mapping requirements to service plans, you can systematically eliminate license options that lack the required plan.
Frontline workers are deskless, shift-based employees who need communication, scheduling, and task management tools.
F1 license costs ~$10/user/month and includes Teams with Shifts, Walkie Talkie, Tasks, Approvals, Viva Connections, and Viva Learning.
F3 license costs ~$20/user/month and adds desktop Office, Power Apps, Power Automate, Planner, Forms, and a 50 GB mailbox.
Neither F1 nor F3 includes Power BI Pro, advanced compliance, or enterprise voice features.
F1 mailbox is limited to 2 GB (Exchange Kiosk); F3 mailbox is 50 GB (Exchange Plan 1).
Choose F1 for workers who only need mobile access; choose F3 for those needing desktop Office or Power Apps.
Always map worker requirements to service plans to select the correct license on the exam.
