Microsoft 365 licenses now power over 400 million paid commercial seats worldwide, according to Microsoft’s FY24 Q3 Earnings Report. Widespread usage, however, is not the same as strategic usage, as many companies are slowly learning.
Shelfware (paying for features and software that sit unused) can drain budgets across organizations of every size. The structure of your licensing approach directly impacts your margins, your team’s productivity, and your ability to invest in growth.
This guide covers what you need to know to stop overpaying, including:
- The difference between Business and Enterprise licensing tracks
- How to align licensing tiers with actual usage
- Practical optimization strategies that free up budget space
First, it’s worth understanding what you’re actually buying; let’s go over the basics of Microsoft’s license offerings.
An Overview of Microsoft 365 Licenses
Before diving into plan-by-plan comparisons, it helps to have a clear mental model of how Microsoft structures its offerings. The entire portfolio of licenses split into two distinct tracks based on organization size.
Business plans cap at 300 users, making them purpose-built for SMBs and growth-stage companies. Enterprise plans carry no user ceiling and offer deeper compliance, analytics, and administrative controls. Choosing the wrong track from day one often means either overpaying for features you can’t fully use (or, worse, not having the communications you need during usage peaks).
It’s also worth clarifying a bit of terminology here: Microsoft 365 is not simply a rebranded Office 365. Microsoft 365 bundles security tooling, Windows OS rights, and productivity apps into a single, integrated platform.
That design philosophy is admirable, though unlike other UCaaS software, Microsoft 365 is focused on a much narrower band of use cases.
Finally, remember that a subscription and license are very different. Your subscription is the contractual agreement with Microsoft, i.e. the billing relationship. A license is the individual seat assigned to a user. Most organizations will have plenty of licenses, but only one subscription.
So, what tier fits your business scope best?
Business Licenses: Scaling from Startup to Mid-Market
Understanding where your company sits within the Microsoft 365 business plans lineup is often the fastest way to eliminate shelfware spending, but there are so many overlapping terms that it can be hard to keep track of it all! Let’s examine each option in brief.
Microsoft 365 Business Basic
Best for: Remote-first teams and lean startups relying entirely on cloud workflows.
- Web and mobile versions of Office apps (no desktop installs)
- Exchange, Teams, SharePoint, and OneDrive included
- 1 TB cloud storage per user
- Capped at 300 users
Basic is the most affordable entry point, but teams needing offline desktop productivity will quickly hit its limits.
Microsoft 365 Business Standard
Best for: Established small-to-mid firms that depend on full desktop Office apps.
- Full desktop installs of Word, Excel, PowerPoint, and Outlook
- Everything in Basic, plus Teams webinars and video editing tools
- Microsoft Loop and co-authoring capabilities
Standard is where most growing businesses land, and for good reason. It balances functionality with cost without overextending the budget.
Microsoft 365 Business Premium
Best for: B2B companies handling sensitive client data or operating in regulated industries.
- Microsoft Intune for device management and mobile security
- Azure Information Protection for data classification and encryption—both absent from Basic and Standard tiers, per Microsoft’s official licensing documentation
- Advanced threat protection and Conditional Access policies
- Entra ID P1 (formerly Azure AD Premium)
Skipping Premium to save $10–$15 per user per month isn’t worth it if a single data breach can cost hundreds of thousands of dollars. For B2B organizations scaling beyond 50 seats, Premium’s security layer typically becomes non-negotiable, doubly so depending on the industry and the amount of sensitive information you handle.
Skip the Licensing Confusion with Intermedia
If all of this seems complex to you, that’s because it is, and worse, these licensing restrictions can cause awkward “growing pains,” where your business is simultaneously too large to fully benefit from a lower-tier plan, yet also not quite big enough to justify the expense of a higher tier.
That’s where Intermedia can simplify things.
We offer the full Microsoft 365 suite, along with all the other communication wins your company needs. The best part? You get the full support of our onboarding team, alongside detailed Microsoft 365 licensing FAQs, so you don’t have to fumble through support articles alone.
It’s easy to scale your business with Intermedia, without needing to constantly re-examine licenses, fee structures, and email architecture. Furthermore, you don’t have to compromise with lower-tier options that might lack critical features from others.
For example, a smaller medical office might need encryption for healthcare emails, yet not benefit from the other commercial-grade features in Microsoft’s Business Premium license, which can leave your organization on the hook for excessive fees.
Intermedia, conversely, has designed our solutions to support HIPAA compliance at every level, with full end-to-end encryption, access restriction options, and robust cybersecurity to protect the sensitive information of your clients, all while allowing you to use your preferred Microsoft app ecosystem.
Enterprise Licenses: E3 vs. E5 for Global Operations
Once your headcount approaches a 300-seat ceiling, the Business tier often can’t keep up, which is exactly where the Enterprise tier enters the picture. These plans are built for organizations with complex compliance obligations, multi-region operations, and dedicated IT teams. This tier comes with two basic license types, namely E3 and E5.
E3 is the enterprise baseline. It bundles the full Office app suite, advanced compliance tools, identity management, and information protection. For most organizations, E3 covers roughly 80% of daily operational needs, without any frills.
E5 is the “all-in” tier. According to Microsoft Enterprise Licensing Resources, E5 includes advanced analytics through Power BI and sophisticated security features like Defender for Endpoint, plus enterprise Voice capabilities that can replace standalone telephony costs entirely.
The pricing gap between the two is significant, often reaching $15–$20 per user per month, which can add up over hundreds of seats.
- Choose E3 if: Security needs are standard, no telephony migration is planned, and analytics requirements are moderate.
- Choose E5 if: Advanced threat intelligence, unified communications, and Power BI Premium are active priorities.
The honest take? Most companies don’t need E5 for every employee. What typically happens is that blanket E5 deployments generate shelfware, and just aren’t worth the excessive fees compared to a proper unified communications solution with Microsoft integration. Plus, Microsoft’s voice service doesn’t bring the level of quality and reliability that businesses truly need.
Enterprise communication software typically costs less, offers more features and better call quality, and integrates better with a wider array of CRMs and apps (including the Microsoft suite itself, ironically). For example, Intermedia Unite comes fully embedded in Microsoft Teams, so users get the high quality voice capabilities of Unite directly inside the Teams app they are already using, for a seamless experience and easier user adoption. Plus, Intermedia offers full Contact Center and Archiving integrated with Teams, creating a complete communications ecosystem integrated with the Microsoft tools your team already uses.
Manage Your Microsoft 365 Suite the Easy Way
The right Microsoft 365 license is a foundation for secure, scalable business growth, but it can be frustrating trying to wade through an opaque fee/feature ecosystem. Your infrastructure and your growth strategy should be united in every way.
