I had this question after viewing RPC Proxy can't be pinged.  I am preparing for the staged migration to O365 from Exchange 2003,  the Outlook Connectivity test , manually specifying server settings, using basic authentication, fails with the following, but with different exceptions from the previous question.  Our inside domain name is the same as outside. I am able to successfully use https://  public IP address/owa.  Any help will be appreciated.
