I reply here to make it more visible to other for future references.
I opened a SR to MS and after some months of investigation, here the result:
“It seems that neither cloud hosted nor on-premises D365 are compatible with On premises Exchange.
According to Product Group Team this is not supported for now and there are no plans, at least for now, to remediate this.” (September 2019)

Going a bit more in detail:
D365 tries to send an authenticated request, with an authentication method that Exchange Web Services (EWS) does not support. D365 uses Claims (ADFS) and EWS does not, by design. EWS supports only Basic, NTLM or OAuth.

Still, both D365 ffo cloud/onPrem support Exchange Online
