Microsoft Graph API support for on premise Exchange

[cstest cstest]

Hi,

Would like to know whether Microsoft Graph APIs support on premise Exchange. Thanks.

Best regards

No. Graph doesn't even support Exchange Online :)

@Vasil Michev as far as I know Graph API works very well with online Exchange Server.

I think it is possible now (Public Preview) but you need to have a Hybrid Exchange scenario.

This doesn't actually work.

In specific, check out the following statement in the subsequent link of the shared link:
"But we have no plans currently to change the way EWS works on-premises, so using Graph for Exchange Online and EWS for Exchange Server on-premises is the current recommendation."

(this comes with the hint that you can also enable OAuth in EWS for accessing Exchange Online only, if the Graph API switch does not work for you)
