I am trying to connect calendly to my Exchange calendar. My attempts have so far been unsuccessful.
I am sure that the data entered ist correct.
MS Connectivity Analyzer says that everything is correct.
Accessing EWS through curl is successful
Accessing EWS through Browser is successful
So why the troubles connecting calendly to exchange?

    Hi ​@Andreas01168 - Thanks for reaching out!

    If you’re running an on premise exchange server, there are IP addresses you can white list to allow the Calendly connection through - Have you already implemented these? 

    If you don’t have them on hand, I’d recommend contacting our team at support@calendly.com as these addresses are not posted publicly.

    Let me know if you have any questions!
