Cannot send mail via Splunk

[neok-g]

Hi,

I have configured Splunk email via Server Settings  - Email Settings:

Mailhost: smtp-mail.outlook.com:587

Enable Ssl: true

Username: xxx@outlook.com

Password: xxx

I am trying to test this mail configuration via the following command:

index=main | head 5 | sendemail to="my-email" server="smtp-mail.outlook.com:587" subject="Here is an email notification" message="This is an example message" sendresults=true inline=true format=raw sendpdf=true

The error I got is: command="sendemail", ('No cipher can be selected.',) while sending mail to: my-email

It does not seem a SMTP error. Anyone who can help?

Thanks!
