Microsoft 365 pricing in 2026 — and what you're really paying per active user.
Microsoft 365 lists Business Standard at $13/user/mo and Business Premium at $22/user/mo — but you're billed per provisioned user, not per active one. A 200-user Business Standard workspace with a 23% ghost-seat rate burns about $6,900/yr on Microsoft 365 accounts that never get used. On Business Premium that's $12,144/yr. Below: the real per-user math, plus how to find and reclaim inactive Microsoft 365 users.

How to find inactive Microsoft 365 users
SeatMap.AI flags a Microsoft 365 user as a ghost when any of these signals fire — and shows you the exact evidence before any seat is touched.
- No Outlook, Teams, or OneDrive sign-in in 60+ days
- Ex-employees on Azure AD with active M365 license
- E5 license assigned but Defender / Power BI never used (downgrade to E3 or Premium)
- Business Premium for users who only need Basic (Teams + email)
- Shared mailboxes billed as full users (should be free)
How to reclaim Microsoft 365 users (the safe way)
- Audit first. Connect Microsoft 365 via read-only OAuth. SeatMap runs the first scan in under two minutes and ranks inactive users by monthly cost.
- Review the queue. Every flagged account shows the rule that fired, last activity, and projected savings. Mark execs and on-call staff as Protected so they never enter the queue again.
- Send the warning. A 24-hour email goes to the affected user and their manager with a one-click bypass link. Active users self-rescue in seconds.
- Reclaim runs. After the bypass window closes, SeatMap unassigns or deactivates the user — data preserved, access removed. Your next Microsoft 365 invoice drops.
- Undo if needed. Every reclaim is logged with the original permissions. One-click re-provision restores the account exactly as it was.
Microsoft 365 pricing FAQ
How much does Microsoft 365 actually cost per user?
Business Basic is $6/user/month, Business Standard $12.50, Business Premium $22, E3 $36, E5 $57 — all billed annually. The single biggest waste pattern: paying for E5 ($57) when the user only uses E3 features ($36) — that's $252/user/year in pure overage.
How do I find unused Microsoft 365 licenses?
M365 admin center shows last activity but doesn't rank licenses by waste. SeatMap.AI connects via read-only Graph API, lists every license with no Outlook/Teams/OneDrive activity in 60+ days, and flags E5 users who never touch E5-only features (Defender, Power BI Pro) for downgrade.
Does Microsoft 365 charge for ex-employees?
Yes, until the license is unassigned. Azure AD will mark an account disabled but the M365 license keeps billing. This is the #1 source of M365 overspend — accounts disabled at HR/Azure AD but never unassigned in the M365 admin.
Should I downgrade E5 users to E3?
Usually yes, unless they actively use Defender for Endpoint, Power BI Pro, advanced compliance, or audio conferencing. SeatMap.AI matches actual feature usage to license tier and flags downgrade candidates. Saving $21/user/month adds up fast at scale.
Are shared mailboxes billed as users?
No — shared mailboxes under 50 GB are free. But many orgs accidentally license them as full users, which is pure waste. SeatMap.AI catches this pattern.
Can you negotiate Microsoft 365 Enterprise pricing?
Yes — Enterprise Agreements are heavily negotiable, especially at renewal and especially with documented usage data. Microsoft reps will right-size if you walk in with real active-license counts. Most teams reclaim 15–25% on the first renewal cycle after an audit.
What's the difference between disabling and unassigning a license?
Disabling the user blocks sign-in but keeps the license assigned and billing. Unassigning the license stops the charge but lets the user sign in if not also disabled. To actually stop paying, you must unassign the license. SeatMap.AI does both in one action.
