Unable to send email

Elastic Stack Elasticsearch
1

I am trying out one of the watcher examples given here: https://www.elastic.co/guide/en/watcher/current/watching-marvel-data.html#watching-cpu-usage.

I have configured exchange using the guide: https://www.elastic.co/guide/en/watcher/current/email-services.html#exchange.

watcher.actions.email.service.account:
    exchange:
        email_defaults:
            from: from@domain.com
        profile: outlook
        smtp:
            auth: true
            starttls.enable: true
            host: email.host.server
            port: 443
            user: username
            password: "password"

I get the following error message when the watch triggers an alert:

[2015-06-13 14:16:34,871][ERROR][watcher.actions.email    ] [transport_client_host] failed to execute action [cpu_usage/send_email]

Not sure what is missing. One thing that I do notice is that my exchange server host in my mail client (like apple mail or outlook) is actually defined as email.host.server/EWS/Exchange.asmx but when I used this I get the following error:

Any idea what could be missing?

For server urls like email.host.server/EWS/Exchange.asmx should there be another path parameter defined so that one can configure the path separately?

something like:
smtp.host: email.host.server
smtp.host.path: /EWS/Exhange.asmx

Based on this link: https://scottlinux.com/2014/06/05/check-for-smtp-tls-from-command-line-with-openssl/, it appears like my mail server does not support SMPT-TLS. Does it mean that watcher cannot work with my setup?

Any suggestions?

Alright... the following setting works for me:

watcher.actions.email.service.account:
    exchange:
        email_defaults:
            from: $your.from.address
        profile: exchange
        smtp:
            auth: false
            starttls.enable: false
            host: $your.mail.server
            port: $your.port
