Office 365 vs Microsoft 365 Enterprise Pricing (300+ Users)
For large corporations, government entities, and highly regulated industries, the distinction between Microsoft 365 vs Office 365 still exists in the Enterprise (E) tiers.
Here is how the legacy Office suite stacks up against the modern enterprise cloud solutions bundle.
| Feature / Plan | Office 365 E3 | Microsoft 365 E3 | Office 365 E5 | Microsoft 365 E5 |
| Est. Monthly Price | ~$23.00 / user | ~$36.00 / user | ~$38.00 / user | ~$57.00 / user |
| Desktop Apps | Yes | Yes | Yes | Yes |
| Email & Teams | Yes | Yes | Yes (with Voice) | Yes (with Voice) |
| Windows 11 Enterprise | No | Yes | No | Yes |
| Microsoft Intune (MDM) | No | Yes | No | Yes |
| Advanced Defender | No | Yes (Plan 1) | Partial | Yes (Plan 2 / Max) |
| Power BI Pro | No | No | Yes | Yes |
Why upgrade to Microsoft 365 Enterprise?
While Office 365 E3/E5 saves you money upfront, it leaves massive gaps in your IT infrastructure. If you buy Office 365 E3, you still have to purchase separate Windows OS licenses for your fleet and third-party security software (like CrowdStrike or SentinelOne). Microsoft 365 Enterprise consolidates these costs into one predictable bill.
The Hidden Costs of Choosing the Wrong Plan
When comparing Microsoft 365 vs Office 365 pricing, the biggest mistake IT procurement teams make is only looking at the subscription fee. You must factor in the “Hidden Costs of Not Upgrading.”
Vendor Sprawl: If you buy a cheaper plan, you will likely spend more money subscribing to external services for Mobile Device Management (MDM), email encryption, and antivirus software.
Compliance Penalties: If you handle healthcare or financial data, cheaper plans lack the Data Loss Prevention (DLP) and eDiscovery tools necessary to pass regulatory audits.
Migration Costs: Starting on a disjointed legacy system means you will eventually have to pay for an Office 365 to Microsoft 365 Migration Checklist execution.
Additionally, in 2026, AI is a massive consideration. Microsoft Copilot (the AI assistant) requires specific baseline licenses to operate. If your foundation is wrong, you cannot leverage AI productivity tools later.
