How to fix email authentication unsuccessful?

[vinod743374]

Alerts suddenly stopped in my local instance, i am getting the error like in the above image, can anyone please suggest the solution for this, i didn't change my email password, its same when it is in working and now also.

I configured my outlook mail with an app password.

I recreate the app password and configure but i am still facing the issue.

Thankyou.

The error seems very clear - the credentials are wrong.  Verify the values at Settings->Server settings->Email settings are correct.  Consider changing the SMTP password and updating the settings in Splunk.

Even if I entered the correct password,
I am getting the error like above image.

I tried numerous times and got nothing.

even I reset the mail password and then recreate the app password.
