The trick was changing the changing the Authentication type to Basic:
Why this is, I have no idea. Earlier Exchange versions still work with NTLM authentication.
As suggested in my question, it looks as if something changed with Exchange Online in the same period that I upgraded SOAPUI.
The MS article Authentication and EWS in Exchange dated 9. March 2015:
- says that NTLM is for *Exchange on-premises only* - which definitely was not true during the larger parts of 2015 and 2016, when I used SOAPUI with the NTLM setting;
- suggests that I stop using Basic as well, but for now it's a solution.
