Understanding Microsoft 365 E5 Security Licensing with Office 365 E1/E3
Question details
The user needs clarification on whether an Office 365 E1 or E3 subscription qualifies them to purchase and use Microsoft 365 E5 Security add-ons.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Planning enterprise subscription upgrades or purchasing security add-ons for an existing Office 365 environment.
- Observed behavior
- There is confusion regarding licensing prerequisites because similar product names, such as Office 365 E3 and Microsoft 365 E3, have different add-on eligibilities.
Log in to your Microsoft 365 Admin Center to verify your current active subscriptions and review your enterprise license agreements before exploring add-on options.
Verify Prerequisites and Consult Microsoft Licensing Specialists
Confirm your base license tier and consult with Microsoft Sales, as Office 365 E1/E3 often differs from Microsoft 365 E3 regarding E5 Security add-on eligibility.
Microsoft 365 E5 Security and Compliance add-ons are typically designed for and available to customers who already hold Microsoft 365 E3 subscriptions.
Office 365 E1 or E3 are different products from Microsoft 365 E3. Never assume that an Office 365 E1 or E3 license alone qualifies you for Microsoft 365 E5 Security without an underlying Enterprise Mobility + Security (EMS) or Windows Enterprise dependency. You must review the current terms for your specific tenant.
Go to the Microsoft 365 Admin Center, navigate to Billing in the left-hand menu, and click on 'Your products' to confirm whether you hold an Office 365 E1/E3 or a Microsoft 365 E3 license.
Review Microsoft's official licensing documentation for the E5 Security add-on to check if your specific base license requires additional EMS purchases to meet technical dependencies.
Reach out to your Microsoft account representative or contact Microsoft Sales directly through the official support portal to get a definitive answer tailored to your organization's configuration.

Frequently Asked Questions
Is Office 365 E3 the same as Microsoft 365 E3?
No. Microsoft 365 E3 includes the Office 365 E3 suite plus Enterprise Mobility + Security (EMS) and Windows 11 Enterprise, making it a broader bundle that qualifies for advanced E5 Security add-ons.
Can I add Microsoft 365 E5 Security to an Office 365 E1 license?
Typically, Microsoft 365 E5 Security add-ons require a Microsoft 365 E3 base license. Office 365 E1 does not usually meet the prerequisites without other substantial upgrades. Always verify current terms with Microsoft Sales.
Why is there a technical dependency on EMS for E5 Security?
Many E5 Security features rely heavily on Azure Active Directory Premium and Microsoft Intune, which are components of Enterprise Mobility + Security (EMS) bundled into the broader Microsoft 365 E3 license.
How can I check my current active Office or Microsoft 365 licenses?
You can check your active licenses by logging into the Microsoft 365 Admin Center as a global or billing admin, expanding the 'Billing' section, and selecting 'Your products' to view your exact active plans.
