Email account are 365 and add app in azure are config Azure Tendant ID and Azure client ID

Has anyone experienced this error?

My initial thoughts:

• "Unable to find type [Microsoft.Exchange.WebServices.Data.OAuthCredentials]" sounds like this isn't using the latest version of Exchange Web Services as OAuthCredentials are only supported in EWS 2.2.
• The second error suggests one of the following per the wiki:
  • The Autodiscover URL is not defined
  • The Autodiscover URL is defined incorrectly
