Microsoft 365 is powerful—but it’s easy to overpay if you don’t actively manage it. Here are five proven strategies IT teams can implement to lower the Microsoft 365 bill, reduce costs, and ensure they’re only paying for what they actually use.

To optimize Microsoft 365 costs effectively, a proactive approach involving audit, usage analysis, and license reassignment is crucial. It includes consolidating apps, leveraging existing licenses, and proactively reclaiming or downgrading licenses. Implementing a license lifecycle policy, utilizing tools for continuous monitoring, and embedding cost optimization into the organizational culture also contribute to long-term savings.  

1. Audit Your Current Licensing and Usage:

Inventory: Conduct a thorough inventory of all M365 licenses, including quantity, type, and annual/monthly costs.

Compare: Compare this inventory against active users and their usage patterns.

Monitor: Regularly monitor utilization using M365 usage analytics to track application usage, storage, logins, etc.

‍

Here are 5 Microsoft 365 cost optimization strategies that can effectively reduce spending:

1. Right-size your licensing:

Analyze your user profiles and identify those who need less costly license plans. For example, not all users need E5 licenses, and many can be downgraded to E3 or even less expensive options.  

2. Audit and monitor usage:

Regularly check license utilization, identify underutilized licenses, and reassign them to users who need them.  

3. Automate license management:

Implement license provisioning, reassignment, and retirement automation based on user changes and offboarding.  

4. Understand and leverage entitlements:

Before acquiring new add-ons or services, fully explore the features already bundled with your E3 or E5 licenses. Many organizations don't realize the vast capabilities they already have.  

5. Be strategic with add-ons:

Carefully evaluate the need for add-ons like Defender for Office 365 Plan 2 or Purview Audit (E5) before purchasing, as they can significantly increase costs.

✅ 1. Right-Size Your Licenses

Assign licenses based on role and actual usage:

• Use F3 for frontline workers
• Use E3 instead of E5 if advanced security features aren't required
• Don’t assign E5 by default—it costs ~$15 more per user/month

🎯 This strategy alone can optimize Microsoft 365 licenses and save thousands monthly.

✅ 2. Reclaim & Reassign Unused Licenses

Many companies leave licenses active for:

• Departed employees
• Dormant users
• Disabled accounts still consuming licenses

💡 Reclaiming these can reduce Microsoft 365 costs by 15–25%.

✅ 3. Audit App Usage Regularly

Use built-in M365 reports or SaaS tools to track:

• Apps never used (e.g., Teams Phone, Power Automate)
• Add-ons that go unused
• Users not logging in for 30+ days

🔍 This helps optimize Microsoft 365 bills by eliminating non-essential spending.

✅ 4. Avoid Overprovisioning During Onboarding

Instead of provisioning the highest-tier license for every new hire:

• Assign a minimal license first
• Upgrade only if the job requires more access

📉 This keeps your Microsoft 365 pricing lean and scalable.

✅ 5. Run an ROI Calculator

Ask the key question:
"Are we getting what we’re paying for?"

Use a Microsoft 365 ROI calculator to:

• Identify overspend
• Estimate reclaimable licenses
• Improve your IT budget planning for 2025

How Much Does Microsoft 365 Cost?

• E1: ~$10/user/month ‍
• E3: ~$23/user/month ‍
• E5: ~$38/user/month
  100 unused E5 licenses = $3,800/month wasted
