Microsoft 365 F licenses for frontline workers. What F1 and F3 cover, and who belongs on them.

Microsoft 365 F1 and F3 license frontline and deskless workers for web and mobile use at $3 and $10 a month, against $39 for E3. The limits on desktop apps, mailbox size and screen size decide who fits.

This guide is for license managers who carry large frontline or deskless populations on Microsoft 365. Read it alongside our hybrid work licensing guide, which covers the desk based side of the same tenant, and the Microsoft Practice page.

What are Microsoft 365 F SKUs?

Microsoft 365 F1 and F3 are the frontline plans, for staff who work on shared devices, phones and the web instead of a dedicated PC. From July 1, 2026 they list at $3 and $10 per user per month on annual commitment, against $39 for E3 and $60 for E5. Microsoft presents both on its frontline worker page.

Both plans share the identity and device management base of the E plans, Microsoft Entra ID P1 and Intune Plan 1, along with Teams, SharePoint and 2 GB of OneDrive storage. What they leave out is the desktop Office suite, a full mailbox and most of the premium security and analytics stack.

Who counts as a frontline worker?

Microsoft draws the line by how people work. In its own documentation, information workers typically work at a desk on a PC or laptop. Frontline workers spend the day away from a desk, mostly on tablets or phones, and deal directly with customers, the public, or the making and distribution of products.

In practice the F plan population falls into three groups:

• Retail and hospitality. Point of sale, floor and front desk staff.
• Manufacturing and logistics. Shop floor, warehouse and distribution staff, often sharing a kiosk or a handheld scanner.
• Healthcare and field. Shift clinicians and nursing staff, service technicians and other mobile workers who check schedules and complete forms on a phone.

Job title alone does not settle it. A warehouse supervisor who builds rotas in desktop Excel every week is an information worker for licensing purposes, even when the rest of the team is not.

What did the July 2026 price update do to F SKU pricing?

Frontline plans took the largest percentage increases in Microsoft's July 1, 2026 price update. F1 rose by a third and F3 by a quarter, while E3 and E5 each rose by $3. The gap per seat is still wide, but narrower.

If your agreement carries a price hold agreed before July 2026, the older figures apply until that hold expires. Our guide to the 2026 price increase covers how to handle the renewal that follows it.

How do Microsoft 365 F1 and F3 differ?

F1 gives a worker identity, Teams and read only access to Office files. F3 adds editing in Word, Excel, PowerPoint and OneNote on the web and on mobile, plus a 2 GB Exchange mailbox. The choice turns on whether the worker creates or edits documents and sends email, and the rights are set out in the Microsoft licensing terms.

Which one fits which worker?

Pick F1 for staff who read and communicate: they check shifts, read procedures, chat in Teams and open a policy document, but never edit a file or need their own inbox. Pick F3 where staff complete a Word form, update an Excel checklist on a phone or email customers and suppliers.

Most large frontline groups need both plans. In a typical store model the floor staff fit F1, while shift leads who file reports and answer email fit F3. Our F1 versus F3 guide works through more role examples.

What does "no mailbox" on F1 mean in practice?

F1 includes the Exchange Kiosk service plan, but only so the Teams calendar and shift features work. Microsoft provisions a mailbox for the user, yet the license gives no right to use it for email.

If F1 users send mail from the provisioned mailbox, perhaps through a mobile client someone configured, you are using a right you have not bought. Block mailbox access for F1 users in Exchange, or license them on F3.

What are the limits of the F SKUs?

The F SKUs exclude the desktop Office apps and cap the mailbox, so they do not fit anyone who lives in full Outlook or desktop Excel. Premium security, compliance and analytics features also sit in higher tiers. The component detail is in Microsoft's licensing documentation.

Microsoft's own guide to switching users from E plans to F plans lists what changes on the day of the switch. Check each item against the people you plan to move:

• Desktop apps. Installed Word, Excel, PowerPoint, Outlook and OneNote drop into reduced functionality mode.
• Screen size. The Microsoft 365 mobile apps are licensed only on devices with integrated screens of 10.9 inches or less, so a large tablet or a laptop needs a different plan.
• Mailbox. Storage falls from 100 GB to 2 GB on F3, the archive mailbox goes, and delegate access to other mailboxes stops.
• OneDrive. Storage falls from 1 TB or more to 2 GB, and a OneDrive holding more than that becomes read only.
• Teams features. Town halls and webinars are not available, and Teams Phone users need the separate Teams Phone Standard for Frontline Workers add-on.
• Windows. E plans carry full Windows 11 Enterprise rights. Microsoft limits the F plan Windows right to virtual desktop use for licensed users of a shared device, so a dedicated PC does not keep Enterprise features.

When must you move up from an F SKU?

Move a user up when the role needs the desktop apps, a mailbox over 2 GB or premium security. Anyone who depends on Excel macros, Access or desktop Outlook belongs on E3, and forcing that work onto an F SKU frustrates the user.

For security needs alone, check the add-ons before upgrading a whole group. Microsoft sells F5 Security, F5 Compliance and a combined F5 Security & Compliance add-on for F1 and F3 users, carrying most of the E5 security and compliance capability.

How much do F SKUs save compared with E3?

The saving comes from moving eligible deskless staff off E3 and onto F1 or F3. At list price an F3 seat costs $29 a month less than E3, a 74 percent cut, and an F1 seat costs 92 percent less. Frontline populations are often large, so the total adds up quickly when the fit is right.

Run the same comparison on your own price sheet, because negotiated discounts differ by SKU. Our F3 versus E3 comparison sets the two plans side by side feature by feature.

A worked example: 2,000 deskless staff on E3

Say a company has 8,000 Microsoft 365 users, 5,000 of them deskless, and 2,000 of those deskless staff sit on E3. A role review finds 300 who need the desktop apps, 1,400 who need editing and email, and 300 who only read and communicate.

That is a 66 percent cut in what this group costs at list price. Each of the 300 seats left on E3 carries a documented reason, which helps when a user or Microsoft challenges the change.

How do you confirm eligibility?

Check each frontline role against the F SKU capability list on the Microsoft 365 plans and pricing page, then confirm it with usage data. Eligible roles are those that do not need the desktop apps, a large mailbox or premium security. These sources show what people actually use:

• Microsoft 365 Apps usage report. In the admin center under Reports and Usage, it shows who runs the desktop apps on Windows or Mac and who only uses web or mobile.
• Microsoft 365 activations report. Shows who has activated Office, and on which device types.
• Mailbox usage report and Get-MailboxStatistics. Find every mailbox over 2 GB that would need cleaning up before a switch to F3.
• Get-EXOMailbox. Finds archive mailboxes and retention policies that move mail into them.
• OneDrive usage report. Lists users storing more than 2 GB.
• HR job codes. Show who works shifts on shared devices, which the usage data cannot tell you.

Why we advise against one E3 license for everyone

The usual advice is to standardize on E3 for everyone so administration stays simple. We disagree for any company with a large deskless workforce, because that simplicity means paying the full E3 price for every worker who never opens a desktop app.

Group based licensing in Microsoft Entra ID assigns licenses by group membership, and both F plans include Entra ID P1, so a mixed tenant runs on groups that follow HR job codes. Segment the workforce, license deskless staff on F1 or F3 by real need, and keep E3 for staff who use the desktop apps.

What have we seen in recent Microsoft frontline license reviews?

In 2024 to 2025 I reviewed roughly 25 to 35 Microsoft 365 tenants with large frontline populations. Three patterns came up repeatedly:

• E3 on deskless staff. Frontline staff on E3 made up 30 to 50 percent of the deskless population.
• F3 savings. Moving the eligible ones to F3 cut their seat cost by 60 to 80 percent.
• F1 at scale. F1 fit the largest deskless tier, the staff with no need to edit an Office file.

Those E3 seats usually trace back to a joiner process that gives every new starter the same license. Change that process when you change the licenses, or the next wave of new starters brings the overpayment back.

A frontline worker on a full E3 seat is the most common Microsoft overpayment we find.

What will Microsoft's account team say when you move staff to F SKUs?

Expect resistance, because moving users from E3 to F3 shrinks the revenue on your agreement. Typical lines, with our suggested replies:

• "F licenses are only for people with no computer access." Microsoft's own documentation describes frontline workers by how they work, on tablets or phones and with customers or products. Ask the account team to show you the written rule they are relying on.
• "Your E3 discount assumed this volume, so cutting E3 changes the deal." Ask for the discount on each SKU in writing, and price the F lines on their own terms.
• "You can only reduce at renewal." For annual subscriptions that is often true. Plan the swap for the renewal date and ask for a swap right at each anniversary in the new term.
• "Your frontline users will lose security coverage." Price the F5 Security or F5 Compliance add-on against the cost of keeping those users on E3 or E5 before you accept the point.

Which contract terms should you ask for before moving users to F SKUs?

Ask for these terms in the renewal, while Microsoft still wants the signature:

1. A price hold on F1 and F3 for the full term. The July 2026 update raised frontline list prices by 25 to 33 percent, more than any other plan, so a hold is worth more here than on E3.
2. A swap right at each anniversary. With the right to move users from E3 to F3 or F1 every year, you can act on each review instead of waiting three years.
3. Discounts recorded per SKU. A written discount for every line stops a lower E3 count being used to reprice the F lines.
4. Add-on pricing agreed up front. If some frontline users need F5 Security or F5 Compliance, fix that price now instead of upgrading them to E5 later.
5. Step up at the contract price. Users promoted into desk roles should move from F3 to E3 at the agreed price, prorated for the rest of the term.

If you buy through a CSP partner on annual terms, seats can be reduced only within 7 calendar days of purchase or renewal, so time the swap to the renewal date. Our CSP versus Enterprise Agreement comparison covers the trade offs, and the Microsoft EA Renewal Playbook sets out the wider 2024 to 2026 EA cycle.

When should you plan the E3 to F SKU swap before renewal?

Start a year out, because most of the effort is in the data and in agreeing roles with line managers.

Common mistakes when moving users to F SKUs

• Switching before cleaning up. A user with a 10 GB mailbox is far over the F3 quota on the day of the switch and stops receiving mail, and local PST files cannot be opened without desktop Outlook. Reduce mailboxes below 2 GB and move PST content first.
• Giving F1 to people who email. It looks like the cheapest option until the F1 users turn out to need a mailbox, and then each one needs an F3 seat anyway.
• Ignoring device size. Staff on large tablets fall outside the 10.9 inch limit and need a different plan.
• Leaving licenses on leavers. Frontline turnover is high, and unassigned seats pile up. Our license reclamation guide covers the cleanup.

What to do next

1. Find the population. Identify every deskless and frontline user from HR job codes and the Microsoft 365 Apps usage report.
2. Test each role. Check it against the F SKU capability list: desktop apps, mailbox size, screen size and security.
3. Move by real need. Move eligible staff off E3 onto F1 or F3 at the renewal or anniversary.
4. Keep E3 where it is used. Reserve E3 for staff who work in the desktop apps.
5. Protect F1. Confirm mailbox and security needs before assigning F1, and block mailbox use for F1 users.
6. Write it into the contract. Get SKU level discounts, a price hold on F1 and F3 and an anniversary swap right.
7. Repeat the check. Review frontline eligibility at each renewal and fix the joiner process that assigns licenses.
