exchangelib: Call to https://servername/EWS/Exchange.asmx fails

Hi,

I stumbled over your project and I love it. Before I tried to hack around the old Office365 API to work with my Office365 Calendar which was kinda ugly.

Now I want to include the Calendar of my work Exchange Account as well (which is not hosted on Office365 and therefore not availlable over the Office365 API)

Your library works just fine with my Office365 Account (even adding attachments - I never figured that out using the Office365 API)

Now when I try to connect to the mail server at work I get an exchangelib.errors.TransportError: Unknown failure

After some research I found that for some reason the client should ignore certificate warnings? The Status Code is 500.

Hope that helps Best regards
