How to purchase Exchange Server SE with Microsoft 365 E3

To purchase Exchange Server Subscription Edition (SE) as a Microsoft 365 E3 customer, you will need to follow the specific licensing requirements and processes outlined by Microsoft. While the context does not provide explicit steps for purchasing Exchange Server SE directly through Microsoft 365 E3, it is important to note that Exchange Server SE can be integrated into your existing Microsoft 365 environment. You may want to consult with your Microsoft account representative or the Microsoft 365 admin center for detailed purchasing options and guidance on how to proceed with the acquisition of Exchange Server SE alongside your Microsoft 365 E3 subscription.

Hi 김정연

Thank you for reaching out to Microsoft Q&A forum

As far as I know, Exchange Server SE uses a subscription-based model instead of the old perpetual license with Software Assurance. Microsoft 365 E3 provides CAL equivalency for on-premises Exchange but does not include the server license. Organizations with E3 or E5 can deploy Exchange Server SE without buying CALs, but they must purchase the server subscription license separately through a Microsoft licensing partner or account team, as it’s not available as a standalone CSP SKU.

Since Microsoft has not published a fully detailed, step-by-step official guide for purchasing Exchange Server SE from Ee licenses yet, I recommend you reaching out to Microsoft Volume Licensing support

I truly appreciate your understanding. As community moderators, we have limited resources and cannot directly handle licensing-related tasks

Best regards
