I have that constellation up and running here.
Exchange 2016 CU10 and Evo 3.28.4 on openSUE Tumbleweed.

What does the event log on your Exchange server and/or Domain Controller
say?

I'm don't know for sure, but AFAIK there is no dependency between Evo
and samba/windbind or ntlm_auth.
Only libsoup is amongst the requirements for evo and evo-ews.

You have to look at your Exchange settings, especially the requirements
for Outlook Anywhere. You have to check the correct names of the server
you use in Evo for connection and the correct authentication method,
i.e. either "ntlm" or "negotiate".
You also have to check your AD user for permission to use Outlook on the
web under recipients in ECP.
Is Exchange under your control or do you have to ask an admin?
