Microsoft 365 isn't just Outlook and Word anymore. Your subscription likely includes Teams, SharePoint, OneDrive, OneNote, Planner, Forms, Power Automate, Viva, Defender, Loop and -- depending on your license -- Microsoft Copilot. Each one was built to save time, reduce friction, or replace a tool your team is probably paying for separately.

The problem isn't access. It's training and adoption.

Most businesses follow the same pattern: licenses get purchased, an IT admin sets up accounts, and employees start using whatever they already knew before. Outlook replaces the old email client. Teams replaces one meeting tool but sits next to Zoom, Slack, or whatever messaging platform the marketing team preferred. SharePoint sits mostly empty because most people think it’s the same as One Drive. Power Automate goes untouched. And Copilot? That one often gets activated, ignored, and quietly forgotten because it doesn’t work as well as the Chat GPT they’ve been using for a while.

Why Does Low M365 Adoption Happen?

Low adoption isn't a resistance problem. In most cases, it comes down to three things:

1. No one made a case for change. Employees adopt new tools when they understand what problem the tool solves for them personally. Without a clear "here's how this makes your day better" message, behavior doesn't change.
2. Training was a one-time event, not a habit. A 90-minute onboarding session in January doesn't stick by March. Effective adoption requires repeated reinforcement, real-world examples, and time for teams to build new routines.
3. Rollout was broad instead of strategic. A big-bang deployment -- where everyone gets access to everything at once -- historically produces adoption rates of just 12-22% of licensed users. Structured rollout programs, by contrast, achieve 65-78% adoption.[1]

What Does Unused Software Actually Cost Your Business?

This is where the math gets uncomfortable. Microsoft 365 Business Standard runs around $12.50 per user per month. A 50-person team at that tier spends $7,500 per year. If only 30% of employees are actively using even half the tools included, the effective cost-per-value ratio looks a lot worse than the invoice suggests.

And that's before factoring in Copilot. Microsoft 365 Copilot licenses run $30 per user per month at current pricing. Early adopters report saving an average of 11 hours per user per month in routine task time.[2] If your team isn't using it, those hours aren't being saved -- but you're still paying for the seat.

At Sentry, we see this regularly when we conduct technology assessments. Teams with mature IT environments often discover they're paying for tools they've never touched -- and separately paying for third-party alternatives that Microsoft 365 already includes.

What About Microsoft Copilot Specifically?

Copilot is where the adoption conversation has gotten the most attention -- and for good reason.

Despite 70% of Fortune 500 companies activating Microsoft 365 Copilot, roughly 64% of licensed employees choose not to use it.[3]

That's not a technology failure. It's an adoption and training failure.

The businesses that have gotten it right share one thing in common: they treated Copilot as a change management project, not an IT deployment. They identified champions inside each department, ran scenario-based training rather than feature tours, and measured adoption actively over the first 90 days instead of assuming it would happen on its own.

For more on the training gap specifically, see our earlier piece: The Microsoft 365 + Copilot Training Gap That's Costing You.

How Do You Start Closing the Adoption Gap?

You don't need a six-month project to make progress. Here's a practical starting point:

• Run a utilization audit. Microsoft provides built-in adoption reporting in the M365 Admin Center. Pull the data. Find out which tools your team is actively using -- and which ones they're ignoring. The answers are usually surprising.
• Pick one tool and go deep. Rather than pushing 12 apps at once, choose the feature or product that would deliver the clearest ROI for your team and build adoption there first. Teams, OneDrive, and Copilot are the most common starting points for businesses at the Integrate stage of their technology maturity.
• Assign an internal champion. Every successful technology adoption has someone who owns it -- not just IT, but a respected peer in the department who uses the tool, talks about it, and helps colleagues past friction points.
• Build a training cadence, not a training event. Short, recurring sessions tied to real tasks outperform long onboarding blocks by a wide margin. Even a 20-minute monthly session focused on one specific workflow builds momentum over time.

The Bottom Line: ROI is in the Adoption

Microsoft 365 is one of the most powerful -- and already paid-for -- technology investments most businesses own.

The ROI isn't in the subscription. It's in the adoption.

If your team is living in Outlook and ignoring the rest, you're not getting what you're paying for. And if you're sitting on Copilot licenses with no adoption plan, that's the most expensive unused feature in your stack.

Sentry helps organizations build structured adoption strategies for Microsoft 365 and Copilot as part of our Technology Maturity Model -- from the foundation of Operate, through the critical layer of Secure, and into the Integrate and Innovate stages where tools like Copilot actually change how teams work. If you want to know where your organization stands, start with a technology assessment.

Frequently Asked Questions

What is the average Microsoft 365 Copilot adoption rate for businesses?

The average enterprise Copilot adoption rate sits at approximately 34% of licensed users as daily active users at the 90-day mark. Organizations that invest in structured rollout programs can reach 65-78% adoption, while those using broad, unstructured deployments often see rates as low as 12-22%.

How can I tell if my team is actually using Microsoft 365?

Microsoft provides built-in adoption reporting through the Microsoft 365 Admin Center, including the Adoption Score dashboard. This shows usage data across apps like Teams, SharePoint, OneDrive, Outlook, and Copilot at both the organizational and per-user level.

Why don't employees use all of Microsoft 365?

Low adoption typically comes down to three factors: no clear value proposition communicated to employees, one-time training that doesn't stick, and broad rollouts without a structured change management plan. Employees adopt tools they understand and that save them time -- so the adoption strategy has to start there.

Is Microsoft Copilot worth the cost if my team isn't using it?

No. Copilot's value is entirely dependent on active use. Early adopters who do use it report saving an average of 11 hours per user per month. A dormant Copilot license delivers zero ROI at any price.

What's the difference between a Microsoft 365 license and a Copilot license?

Microsoft 365 is the base productivity suite that includes apps like Outlook, Word, Excel, Teams, and SharePoint. Microsoft 365 Copilot is an add-on AI assistant that integrates into those apps. Copilot requires a separate per-user license on top of an existing Microsoft 365 subscription.

Who can help my business implement and train on Microsoft 365 and Copilot?

Sentry Technology Solutions offers training for small to enterprise teams on Microsoft 365 software apps as well as Copilot.  Sentry also offers comprehensive implementation project management which will help your business get the most ROI from the money you're already investing!
