I cannot get my ePo server to be able to send email through my Exchange 07 server. My server requires authentication but not matter what username and password I try it will not authentiate. I am using ePo version 4.0. This is the error I am getting.
An error occurred while trying to send the test email. Failed messages: com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.1 Client was not authenticated
