Hi Johnny Blaze,
Welcome to Microsoft Q&A Forum!
Have a good day and I hope you're doing well!
Thank you for reaching out with your question about Exchange Server Subscription Edition. I’m happy to help explain how this product is licensed and distributed.
Exchange Server Subscription Edition works a bit differently from traditional standalone products, so you won’t see it listed on the public Volume Licensing Price List. Instead, it’s provided as an entitlement a usage right that comes with certain qualifying licenses.
You’re eligible to use Exchange Server Subscription Edition if:
- You have an active Software Assurance (SA) plan on existing Exchange Server licenses, or
- You hold a qualifying Microsoft 365 subscription (such as E3 or E5), which includes on-premises use rights.
Regarding the CSP and NCE channels, Exchange Server Subscription Edition isn’t offered as a standalone product. However, customers who purchase eligible Microsoft 365 plans through CSP/NCE automatically receive the on‑premises use rights that cover Exchange Server Subscription Edition.
If you'd like to speak with someone directly about licensing options and pricing, you can find a Microsoft partner or reseller in your region here: Find your Microsoft 365 subscriptions partner or reseller
