Answer 1

SOLUTION: I have added https://www.nuget.org/packages/Microsoft.Exchange.WebServices.NETStandard nuget and then RUN apt-get update && apt-get -y install gss-ntlmssp into Dockerfile(for Ubuntu, maybe needs for Debian). Also for Linux need to set UseDefaultCredentials = false for ExchangeService.
