Microsoft 365 License Waste: What Usage Analytics Reveal in Practice

Most Canadian SMBs overpay for Microsoft 365 by 10 to 25 percent. The waste is rarely a single bad decision. It is dozens of small, defensible choices that accumulate over years: a user who left without their license being reclaimed, a frontline worker on Business Premium because that was the default at onboarding, a third-party security product still being paid for after Defender for Business was bundled in. Usage analytics surface all of it in one place.

This piece walks through the four patterns of M365 license waste we see most often, how usage analytics expose each, and what continuous monitoring looks like as opposed to the once-a-year scramble at renewal.

What License Waste Looks Like in 2026

Microsoft 365 license waste falls into four categories. Each is fixable in under an hour once identified, and each tends to be invisible until someone goes looking.

1. Orphaned licenses on terminated employee accounts
2. Tier mismatch (users on a higher SKU than they need)
3. Duplicate tools that overlap with M365 entitlements
4. Shelfware add-ons nobody activated or uses

For a 50-person business on Microsoft 365 Business Premium at CAD $30.80 per user per month, recovering even 10 percent of waste returns $1,848 per year. At 100 employees it is $3,696. These numbers compound year over year.

Orphaned Licenses on Terminated Accounts

The most common waste pattern is straightforward. An employee leaves. HR disables their account. IT does not remove the assigned Microsoft 365 license because Microsoft does not prompt you to. The next billing cycle, you pay for that seat. The cycle after that, you pay again.

We routinely find businesses paying for 5 to 20 percent more seats than they have active employees. The remediation is one screen in the M365 admin center: unassign the license. The catch is that nobody has a process to do this systematically, so the waste accumulates until someone goes looking.

Tier Mismatch: Wrong Plan for the User

Microsoft offers Business Basic at CAD $8.10, Business Standard at $16.50, and Business Premium at $30.80 per user per month. There are also Frontline (F) plans at substantially lower price points for shared-device and deskless workers, plus the Enterprise (E3, E5) plans for businesses that have outgrown the Business tier cap of 300 users.

The tier-mismatch waste looks like this:

• A receptionist on Business Premium who only ever uses Outlook web and Teams chat. Business Basic would do everything they need at a quarter of the cost.
• A warehouse worker assigned a Business Premium license at $30.80 when an F1 or F3 Frontline plan at a fraction of the cost covers their actual use.
• An entire team on E5 because the CFO needed advanced compliance features once, and E5 became the default.

Usage analytics reveal each user's actual product engagement: are they using the desktop apps that justify Business Standard, the device-management features that justify Business Premium, or only the web apps that come with Basic? The signal is unambiguous in the data even when the human answer is ambiguous.

Duplicate Tools You Already Own

Microsoft 365 Business Premium bundles tools that most SMBs separately pay for elsewhere. The most common duplicates we find:

• Third-party antivirus when Defender for Business is already included and substantially better
• Standalone MFA tools (Duo, Okta SSO, etc.) when Azure AD Premium P1 provides MFA, conditional access, and SSO natively
• Dedicated mobile device management (MDM) when Intune is included and covers Windows, Mac, iOS, and Android
• Email signature management tools when newer M365 capabilities handle this, paired with central signature management for businesses that want stronger control
• Separate cloud storage when OneDrive + SharePoint provide a terabyte per user

Each duplicate is usually $5 to $20 per user per month. Across a 50-person business with three or four duplicates, the recovery is in the low five figures annually.

Shelfware Add-Ons

Microsoft sells dozens of add-ons: Power Apps Premium, Power BI Pro, Project Plan, Visio, Power Automate Premium, additional storage. Some of these get added during a specific project and never reviewed. The project ends; the add-on continues.

Usage analytics show the last sign-in date for each add-on capability per user. The ones nobody has touched in 90 days are usually safe to drop. Often the add-on was bundled with an enterprise plan upgrade that has its own pricing implications, so the right answer is sometimes to drop the upgrade rather than the add-on.

How Usage Analytics Find It

Microsoft 365 produces detailed usage reports across every workload (Exchange, SharePoint, OneDrive, Teams, the desktop apps). The data is there. The catch is that accessing it requires admin access to the Microsoft 365 admin center, navigation through several different report screens, exporting to CSV, and cross-referencing against the license assignment list. Few SMB owners or finance leaders do this regularly.

Continuous Monitoring in ClayGen Connect

ClayGen Connect includes a Microsoft 365 usage view that rolls the relevant reports into a single dashboard, refreshed automatically. The owner sees:

• Total monthly license spend by tier
• Users with low engagement on the apps their tier bundles (the "could be downgraded" list)
• Recently inactive licenses (the "should be released" list)
• Add-ons with no activity in 90 days (the "audit before renewal" list)
• Storage trending toward Microsoft's premium-rate thresholds

Beyond the data, Connect flags concrete savings opportunities each month, so the license review goes from an annual scramble to a regular cadence. For a deeper look at what Connect does end-to-end, see our platform page.

The Quick Audit You Can Run Today

If you want a fast first pass without engaging a provider:

1. Open the Microsoft 365 admin center, then go to Billing and Licenses
2. Cross-check assigned licenses against your active employee count. Investigate any difference greater than zero.
3. In the Reports section, run the "Microsoft 365 Apps Usage" report for the last 30 days. Identify users who have not used any desktop app.
4. Check each premium add-on you are paying for and confirm someone is using it
5. Audit any third-party tools that overlap with Defender, Intune, or Azure AD entitlements

That single hour will typically surface several thousand dollars per year of waste on a 50-person business. For continuous monitoring rather than one-time recovery, see our Microsoft 365 management service, which includes license optimization as a standard quarterly review.
