Hi Ross, can you clarify what part of the REST API is considered to not work On-Prem only?

I can GET https://my.onprem.ex2016/api/v2.0/me/messages and get a list of my inbox messages.

Can we as an ISV move from EWS to the /api/ endpoint for On-Prem only and expect api//... to respond like documented?

We have different customers where some use On-Prem only, some Hybrid and some Online only. Would be nice to see those three scenarios inside your "one endpoint to rule them all" strategy ;-)

    That's a good tip EinmalIM.

    I'm looking at extending our current application with Exchange support through the Graph API. But the biggest problem right now is the lack of on-premise support. So we'll probably end up with needing to support multiple APIs :(
