Furthermore, you can check if the service account can access EWS externally using the following Microsoft Connectivity Tool website: https://testconnectivity.microsoft.com/#&&Jtn0NnPPEC4GA7XXbfXtBsFMMpLP/1L9WRZephR4rWelHOpg2VRYAX7jbAcDJs4ZkdyCar8vg26eu7AkKZoYKtOM31mA5mwffO0Ze13OWZIryQ46PWeIbQB3OqBpKnvJl++a3peWGzuLYsJsGT+II2Uze06Yh2pDRKO3CtarEfKtDVl0HmxLhPN9JKIZe9pwmeaScw==
