Strange error in auto-discover using EWS... RRS feed

  • Question

  • Hi,

    The test environment:

    Parent domain: parent.domain.

    Child domain: child.parent.domain

    SMTP domain: smtp.domain

    SIP domain: sip.domain

    Test PC join the "child.parent.domain" and login with "child\test1", this account's email address is "test1@sip.domain", outlook in this PC works fine, but EWS raise a exception about getting user settings.

    EWS auto-discover code:

    AutoDiscoverExchangeWebServices

    {

    ...

    _ExchangeService = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
    _ExchangeService.TraceEnabled = true;

    _ExchangeService.AutodiscoverUrl("test1@sip.domain", AutoDiscoverValidationCallback);

    ...

    }

    Logs:

    This looks like some error in server configuration. How is exception raised? Where to check the configurations?

    Thanks very much.
