Hi,

I am using EWS Java API 2.0 to access user mailboxes from Exchange 2019 and O365 using autodiscoverUrl() method as EWS URL might change with new Client Access servers.

PFB the code snippet:

 private static ExchangeService exchangeService;

    private static void usingAutodiscovery() {
        exchangeService = new ExchangeService();
        try {
            exchangeService.setTraceEnabled(true);
            exchangeService.setCredentials(new WebCredentials("username", "password", "domain.com"));
            // Set the URL.
            exchangeService.autodiscoverUrl(username@domain.com, new RedirectionUrlCallback());

            Folder inbox = Folder.bind(exchangeService, WellKnownFolderName.Inbox);
            System.out.println("messages: " + inbox.getTotalCount());

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        usingAutodiscovery();
    }

    public static class RedirectionUrlCallback implements IAutodiscoverRedirectionUrl {
        public boolean autodiscoverRedirectionUrlValidationCallback(String redirectionUrl) {
            return redirectionUrl.toLowerCase().startsWith("https://");
      }
    }
}

But I am getting the below error:

microsoft.exchange.webservices.data.autodiscover.exception.AutodiscoverLocalException: The Autodiscover service couldn't be located.

We have below details configured:
AutodiscoverInternalUri = https://autodiscover.domainname.com/Autodiscover/Autodiscover.xml
External EWS URL = https://domainname.com/ews/exchange.asmx

    Hi @ExchangeOnline444 ,

    Try to replace 

    exchangeService.setCredentials(new WebCredentials("username", "password", "domain.com"));

    with 

    exchangeService.setCredentials(new WebCredentials("emailAddress", "password"));

    Also test the autodiscover service with ECRCA
    Regards,
    Lou
