I am getting an autodiscover error when configuring the Outlook Input Tool weather i go with the defaults or manually select service URL. The only potential issue I see is that the available Exchange Server Version provided maxes out at 2013 and we are on 2016. Could this matter and if so how can i update that component in the tool.
Could you please upload your workflow and some sample data?
If possible, please send a screenshot of the output tools setup, and a screenshot of the error message.
