Microsoft 365 licensing, the bill is decided by placement
Microsoft 365 is licensed per named user across a handful of plan families, and the whole cost story comes down to placing each person on the lowest tier that still covers their real work. Across the estates we reviewed, the cost story was almost never the negotiated rate; it was tier placement, and it drifted upward wherever nobody reviewed it.
Prepared by Redress Compliance · August 7, 2026 · Microsoft advisory. Based on 35 to 45 Microsoft 365 estates reviewed 2024 to 2025.
Executive summary
The license follows the person, not the machine. One named user license covers up to five PCs, five tablets, and five phones, so the unit of cost is the headcount on each tier, and device based licensing survives only in narrow shared and kiosk scenarios. That makes the tier mix the entire cost model: the same workforce prices completely differently depending on who sits where.
E5 is a targeted tool sold as a default. The standardize on E5 pitch buys administrative convenience with licenses nobody uses: across our reviews, 10 to 20 percent of E5 seats belonged to people who never touched a premium feature and fit E3. E5 pays off for the specific users exercising its security, compliance, and voice capabilities, and for everyone else E3 covers the productivity core at a materially lower price.
Frontline staff on full E3 seats is the second recurring waste. Workers who live in a browser and on a phone fit the F SKUs, F3 with web and mobile Office and a small mailbox, F1 for identity, Teams, and app access, and estates that never mapped the roles carried full E3 seats for populations an F SKU covered. The third waste is quieter still: standalone add ons duplicating features already inside the assigned plan, paid twice by estates that never reconciled the two.
Placement drifts, so the review must recur. Roles change, people leave, and tiers only ever drift upward without a routine: the quarterly pass against the active usage report is what keeps the seat count and tier mix aligned to real work, and it feeds the same reclaim and reclassify engine the SAM and optimization guide runs across the wider estate. Business plans add one structural check: the 300 seat cap, reconciled before renewal for estates straddling it.
The plan families, and who each is for
| Family | Who it is for | Core tiers | The placement note |
|---|---|---|---|
| Enterprise | Organizations of any size | E3, E5 | E3 fits most knowledge workers; E5 is earned by feature use |
| Business | Under the 300 seat cap | Basic, Standard, Premium | Cheaper per seat, capped: reconcile counts near the ceiling |
| Frontline | Deskless and shift staff | F1, F3 | Web and mobile work belongs here, never on full E3 |
| Add ons | Specific needs on top | Security, voice, compliance | Cancel wherever the assigned plan already includes the feature |
The E5 premium, and who actually earns it
Three populations justify the step up: security teams exercising the advanced threat and identity tooling, compliance heavy roles needing the governance and eDiscovery stack, and voice users where E5 telephony replaces a separate phone system whose cost makes the comparison. Everyone else is an E3 seat wearing an E5 price, and the decision framework, feature by feature against the add on alternatives, is worked in the E3 versus E5 versus F3 comparison. The add on interaction cuts both ways: a targeted add on on E3 can beat a blanket E5, and a standalone add on duplicating what the assigned plan includes is money simply returned by cancellation, the reconciliation the optimization guide sequences.
The Microsoft EA renewal playbook
The negotiation the placement work feeds: the seven levers, the persona mix arithmetic, and the clean data advantage worked on a representative estate.

The mapping is a three step routine: confirm the role works only in a browser and on a phone, choose the tier, F1 for identity, Teams, and app access, F3 where light Office and a mailbox are needed, and reclaim the full E3 seats the population never required. The reclaim mechanics, who to move, in what order, with what communication, are worked in the license reclamation guide, and the license optimizer runs the first pass across the whole estate in minutes from the usage export.

What we saw across Microsoft 365 estates, 2024 to 2025
Across roughly 35 to 45 Microsoft 365 estates Morten Andersen reviewed between 2024 and 2025, the cost story was almost never the negotiated rate:
Of the E5 count, seats belonging to users whose real work fit E3, renewed by default every cycle.
E5 over placement, frontline staff on full E3, and add ons duplicating included features.
The finding that organizes everything else: tier placement across a mixed workforce, not the negotiated discount, decides the real Microsoft 365 bill, and it is decided continuously rather than at signature. The estates that held their costs shared one routine, the quarterly placement review against active usage, feeding reclaims at the true up and an honest persona mix into the renewal, where the negotiated rate then applies to a base worth negotiating on.
Your first five moves
- Inventory every assigned seat by plan and add on, because the placement map is the cost model.
- Map each role to the lowest tier that covers its real work, reserving E5 for demonstrated security, compliance, and voice use.
- Move web and mobile only staff to F SKUs and reclaim the E3 seats they never needed.
- Cancel add ons duplicating included features, and reconcile Business plan counts against the 300 seat cap before renewal.
- Set the quarterly placement review against active usage, so the mix tracks the workforce. The Microsoft practice runs the pass with you.
Frequently asked questions
How does Microsoft 365 licensing work?
Per named user, not per device: one license follows the employee across up to five PCs, five tablets, and five phones, so the unit of cost is the headcount on each plan tier. Device licensing survives only for narrow shared and kiosk scenarios, and the tier mix across the workforce is what actually prices the estate.
What are the Microsoft 365 plan families?
Enterprise with E3 and E5 for organizations of any size, Business with Basic, Standard, and Premium under a 300 seat cap, and Frontline with F1 and F3 for deskless staff, plus add ons layering security, voice, and compliance on top. The family follows organization size; the tier should follow the work.
Who actually needs Microsoft 365 E5?
Users who exercise its premium capabilities: security teams on the advanced threat and identity tooling, compliance heavy roles on governance and eDiscovery, and voice users where E5 telephony replaces a separate system. Across our reviews, 10 to 20 percent of E5 seats belonged to people who never touched a premium feature.
How should frontline workers be licensed?
On the F SKUs, not full E3 seats: F3 adds web and mobile Office with a small mailbox, and F1 covers identity, Teams, and app access for the lightest users. Staff who work in a browser and on a phone fit the F tiers, and moving them off E3 is one of the fastest reclaims in a Microsoft 365 estate.
Is standardizing everyone on E5 a good idea?
No: it buys administrative convenience with licenses nobody uses, funding the premium across the workforce for the fraction who exercise premium features. The buyer side placement, lowest tier per real work with E5 reserved for evidenced need, is harder to administer and materially cheaper to own.
How often should Microsoft 365 placement be reviewed?
Quarterly, against the active usage report: roles change, people leave, and tiers drift upward without a routine. The quarterly pass keeps the seat count and tier mix aligned to real work, feeds reclaims at the true up, and delivers the honest persona mix the renewal negotiation depends on.
