The most common question a worried IT leader asks is also the most useful one: why us. An audit feels arbitrary when it lands, but it almost never is. Microsoft has both the data and the commercial incentive to pick its targets carefully, and in 2026 that selection is increasingly driven by analytics rather than hunches. Understanding what actually puts a customer on the list lets you see your own organization the way Microsoft sees it, and gives you the chance to reduce the signals before they add up to a letter. This article walks through the real triggers, how the modern selection works, and what you can do about each one.
For the full catalogue of triggers and how they combine into risk, the Microsoft audit triggers guide goes deeper. Here we cover the main categories and the logic behind them.
How selection works in 2026
The single biggest change in recent years is that Microsoft no longer relies only on account teams flagging suspicious accounts. It uses anomaly detection across licensing and telemetry to score customers for review. The model compares what you are entitled to against what its own systems can see you using, drawn from Azure, Microsoft 365, and management tooling. Where the two diverge in a way the model finds unusual, the account moves up the list. This means the trigger is not any single event but a mismatch between entitlement and observed usage, and the more visibility Microsoft has into your estate, the sharper that comparison becomes.
The modern trigger is a gap between what you are entitled to and what Microsoft can already see you using. The wider the gap, the higher you score.
The commercial triggers
On top of the analytics sit a set of long standing commercial triggers. These are the events that have always drawn attention because they correlate with licensing gaps, and they still matter.
- A renewal or an Enterprise Agreement coming to term, where a compliance finding strengthens Microsoft's negotiating position
- A sharp change in spend, especially a customer reducing commitment or declining to renew at the expected level
- Mergers, acquisitions, and divestitures, which create entitlement confusion that audits are well placed to exploit
- A history of large true ups or self reported corrections, which signals an estate that moves faster than its licensing
- Public growth, funding, or expansion that does not match a corresponding growth in licensing spend
None of these guarantees an audit, but each raises the probability, and several together raise it sharply. A customer approaching renewal, having just made an acquisition, while reducing spend, is a far more likely target than a stable account with no recent change.
The technical triggers
Alongside the commercial signals are technical ones that the telemetry surfaces directly. These are the gaps the anomaly model is built to find.
- Usage spikes in a product that outpace the entitlements on record for it
- Azure Arc and other management telemetry revealing servers Microsoft did not know were running its software
- Entitlement mismatches where deployed editions are higher than the licenses held
- Identity and Microsoft 365 signals showing more active users than the licenses assigned
- Workloads running across other clouds that still consume Microsoft licensing in ways the records do not reflect
The common thread is visibility. Each of these triggers exists because Microsoft can see something your own records may not show. That is also why a clean internal position is the best defense, because it closes the gap before the model finds it.
A simple risk picture
It helps to think of triggers as additive rather than singular. The table below is an indicative way to picture how factors stack, not a literal Microsoft scoring system.
| Factor present | Effect on risk |
|---|---|
| Entitlement and telemetry gap | Primary driver, raises baseline risk |
| Renewal or EA term approaching | Amplifies, adds commercial incentive |
| Recent acquisition or divestiture | Amplifies, creates entitlement confusion |
| Reduced or declining spend | Amplifies, signals possible exposure |
| Clean, reconciled internal position | Reduces, closes the gap the model looks for |
The point of the picture is that you cannot change some factors, such as the fact that a renewal is approaching, but you can change others, above all the gap between your entitlements and your observed usage. That is the lever worth pulling.
What you can actually do
You cannot stop Microsoft from running analytics, and you cannot avoid every commercial trigger, because renewals and transactions are part of running a business. What you can do is reduce the technical gap and prepare for the commercial moments when risk is highest.
Where this leaves you
A Microsoft audit is the product of a gap and a moment. The gap is the distance between what you are entitled to and what Microsoft can see, and the moment is a commercial event that gives the audit a reason to land now. You cannot remove every moment, but you can shrink the gap, and a smaller gap both lowers your selection risk and strengthens your position if a letter does arrive. Knowing what triggers an audit is not about fear. It is about seeing your estate the way the model does, and fixing what you can before it counts against you.
