Frontline (F1/F3) vs Enterprise (E3/E5) — Free Mind Map
Visual comparison of Microsoft 365 Frontline plans (F1, F3) and Enterprise plans (E3, E5) — costs, included apps, storage, security. Free mind map.
Frontline plans are NOT 'cheap E3'. They're built for shared-device, shift-based workers who barely sit at a desk. Here's the actual comparison.

Frequently Asked Questions
Who actually qualifies as a 'frontline worker'?
Microsoft's official guidance: workers in retail, hospitality, manufacturing, healthcare, transportation, public sector field roles — typically shift-based, often using shared devices, with limited time at a desk. The intent is 'deskless workers who need M365 capabilities at the moment of need'. There's no Microsoft licence audit checking job titles, but plans are sold under licence terms that assume frontline use cases — using F licences for traditional knowledge workers can violate licensing terms.
Why is F1 so cheap? What's missing?
F1 ($2.25/user/month) is the lightest M365 plan — Teams, web Office (read-only on some apps), no Exchange mailbox (just 2 GB inbox-style storage for shared inbox use), no OneDrive personal, no desktop apps. Designed for shared kiosk devices in retail / manufacturing where workers need basic Teams + intranet access only. F3 ($8/user/month) adds proper email + OneDrive + mobile Office editing — the real 'full frontline' tier.
Can we mix F and E licences in the same tenant?
Yes. Most large organisations do — frontline workers get F1 or F3, knowledge workers get E3 or E5. Mixed licensing is fully supported. Conditional Access policies, security policies, and admin tools all work across the mix. Just make sure you're not assigning F licences to people who don't actually qualify as frontline — that's a licensing compliance risk, not a technical one.
Where's Copilot in Frontline?
M365 Copilot ($30/user/month add-on) supports a wide range of base licences — including F1 and F3 — when added on top. Eligible bases include M365 E3/E5/F1/F3, Office 365 E1/E3/E5, Business Standard/Premium, and M365 A3/A5 (faculty only, not students). The standalone Copilot Chat (free, web-grounded) is also available to frontline workers without any add-on. So contrary to a common misconception, frontline workers ARE in scope for paid Copilot — you just need to weigh whether the per-seat cost makes sense relative to a frontline worker's app usage.
