Solution – 

  • Make sure Outlook Anywhere succeeds with test account.
  • Make sure you enter the credentials with domain\username in all locations while creating endpoint.
  • Make sure internal and External host name is in the certificate (In a strange case user ad multi domain wild card cert were we move internal and external hostname to the primary FQDN of the cert)
  • Make sure HTTP redirect is not set EWS virtual directories.

  • Make sure Basic and Windows auth is enabled on EWS virtual directory.
