Exchange Server Team,
Could you please clarify the migration path for customers with Exchange Server 2016/2019 on-premises licenses purchased through the CSP program, which does not include Software Assurance? These customers are unable to transition to Exchange Server Subscription Edition (SE), as SE is not currently available through CSP.

Could you please advise on what options are available for these customers? Ref: ID #2507150040012322 Thank you.
