Karthikeyan_S5 , I am not with Microsoft, but given:
"To allow for rapid adoption and deployment, the RTM release of Exchange Server SE will be code equivalent to (e.g., the same exact code as) Exchange Server 2019 CU15, except for the following changes:
- The License agreement, an RTF file shown only in the GUI version of Setup, will be updated.
- The name will change from Microsoft Exchange Server 2019 to Microsoft Exchange Server Subscription Edition.
- The build and version number will be updated."
Since Exchange 2019 has an Edge Server Role, and the RTM of Exchange SE will have almost identical bits, and given you can perform a one-time, in-place upgrade from Exchange 2019 to Exchange SE, for which you may have deployed the Edge Transport Role, it seems one could reasonably assume the answer to your question is yes, Exchange SE will have an Edge Server Role.
