You wouldn’t buy a Porsche just to drive three blocks to the grocery store at 15 miles per hour. Yet, that is exactly what thousands of businesses do with their software budgets every year. They purchase top-tier, heavy-duty Microsoft 365 licenses for users who only ever open Outlook and Teams.
Industry studies consistently show that 30–60% of SaaS licenses, including Microsoft 365, are inactive, underutilized, or oversized, leaving a significant portion of software budgets sitting unused. That is more than half of the investment sitting on the shelf, gathering digital dust.
Optimizing your licensing stack isn't just about being frugal; it is about architectural hygiene. However, the path to savings is paved with potential pitfalls. Cut the wrong license, and an executive loses their email archive. Downgrade the wrong department, and your compliance posture crumbles.
We are here to help you navigate the fine line between "lean efficiency" and "accidental data loss."
Before we start slashing costs, we have to understand the menu. Microsoft’s ecosystem is vast, but for most SMBs and mid-market organizations, the options fall into three primary buckets.
These are the "light" licenses. Think of the F1 and F3 plans. They are designed for workers who are on their feet, such as nurses, factory floor staff, and retail associates. They rely on mobile apps and web access rather than heavy desktop software.
This is the sweet spot for organizations with fewer than 300 users. It offers a mix of cloud services and desktop apps. Business Premium, in particular, has become the gold standard for SMB security, bundling in advanced protections that used to be exclusive to the enterprise tier.
The heavy hitters: E3 and E5. These plans are built for scale, offering unlimited archiving, advanced eDiscovery, and complex compliance tools. They are powerful, but they are also the most common source of overspending.
Finding money in your budget often comes down to matching the license to the actual human behavior, rather than the job title. Here are the most common safe maneuvers.
For years, the Enterprise E3 license was the default choice for any company that wanted serious security. That changed with the evolution of Microsoft 365 Business Premium.
If your organization has fewer than 300 users, staying on E3 might be a waste of funds. Business Premium now includes Microsoft Defender for Business, Intune, and Entra ID Plan 1. For many SMBs, Business Premium actually offers better security value than a standard E3 license, often at a lower price point. You get the full desktop apps and the security suite without paying for enterprise-grade compliance features you may never use.
Do you have employees who never log into a dedicated desktop computer? Perhaps warehouse staff or field agents who only check email and Teams on a tablet?
Assigning an E3 license to these users is the definition of overspending. Switching these users to an F3 or F1 plan can drastically reduce costs. F-plans provide access to Teams, SharePoint, and web-based Outlook, which is often all a frontline worker requires to stay connected.
In many organizations, there are users who create content and users who only consume it. An executive assistant needs full Excel capabilities to build complex financial models. The executive reviewing that model might only need to view it.
If a user rarely edits documents and lives mostly in the browser, they might not need a license that includes downloadable desktop apps. Moving them to a web-centric plan (like Business Basic) ensures they can still view and lightly edit files without the premium cost of installed software.
Just because you can downgrade a license doesn't mean you should. Stepping down a tier usually involves removing features, and if you aren't careful, you might accidentally remove a load-bearing wall in your security architecture.
This is the most common headache during a downgrade. Enterprise (E3/E5) mailboxes typically come with 100GB of storage. Business-tier mailboxes come with 50GB.
If you move a user with a 75GB mailbox from E3 to Business Premium, their email will instantly stop working. They won't be able to send or receive messages until they delete 25GB of data. Identifying users over the 50GB limit is a critical prerequisite before changing any licenses.
Downgrading from E5 to E3, or from Business Premium to Standard, often means saying goodbye to advanced security features.
If you drop Business Premium for Standard, you lose Intune (device management) and Defender for Business. You are essentially trading your alarm system for a slightly cheaper electric bill. In the current cybersecurity climate, where ransomware is rampant, removing endpoint protection to save a few dollars is a calculated risk that rarely pays off.
Heavily regulated industries (finance, healthcare, legal) often rely on the litigation hold and unlimited archiving features found in the Enterprise tiers. Downgrading to a plan that doesn't support these features could put your organization at risk of violating industry regulations. Always check your compliance requirements before touching the license stack.
Sometimes the waste isn't in the core license; it's in the extras.
How many of your users have a Project or Visio license? Now, how many of them have opened those apps in the last 90 days? SaaS management audits routinely show that 10–20% of specialized Microsoft add-on licenses, such as Project and Visio, go unused. In a 10,000-user organization, reclaiming unused Project licenses alone can translate into tens of thousands of dollars in monthly savings.
Unlike downgrading a core license, removing an unused add-on has zero impact on daily workflows because the user wasn’t relying on it in the first place.
As we explored in our previous discussion, From Licenses to Leverage: Running Microsoft 365 as a Platform, viewing your Microsoft stack purely as a utility bill misses the point. The goal isn't just to pay less; it's to get more value for your money.
A "safe" downgrade isn't just about cutting costs; it's about rightsizing. It’s about ensuring that your security posture (the platform approach) remains intact while shedding the weight of unused features.
When you treat Microsoft 365 as a cohesive platform rather than a bundle of apps, you realize that the license is the foundation of your security. If you downgrade the license, you must ensure you aren't cracking that foundation.
