SMTP service account unable to authenticate with our exchange server

if you look at that jobs parameters in job queue info it will show what it is using for credentials to connect to the Exchange server. Please ensure that it has the correct credentials.

Yes, I have checked. The credential is correct. Still kept getting this error message

I think that something is wrong with the setup see the error message which points to the server and the component not having matching authentication types: 

Errors occurred Server supported authentication mechanisms: NTLM, LOGIN
Component supported authentication mechanisms: XOAUTH2, SCRAM-SHA-256, SCRAM-SHA-1, CRAM-MD5, DIGEST-MD5, PLAIN, LOGIN

Maybe it is trying to do NTLM which is not supported by the component when it should be using just LOGIN. You could always do a network capture to see what is happening when attempting to authenticate.

Are  you using an encrypted connection to the SMTP server using a certificate?

Hi Troy,

I have done the network capture but there is nothing stood out. How do we just using LOGIN? I don't think we are using a certificate though. Any suggestions?

Which version of OneIM are you using?

8.1 

How did you configure the mail notification system of OneIM? Described in the installation guide https://support.oneidentity.com/technical-documents/identity-manager/8.1.1/installation-guide/11#TOPIC-1250162 .

Did you set the parameter SMTPUseDefaultCredentials? And if so, what credentials is the Job Service, executing the mail tasks, using?

After set the use default credential parameter it works! Same credential, but not working if I put the name and password in SMTPAccount and Password.

Because the Job service is running ok so that credential works with OneID. 

Thanks for your help Markus. It is working now
