Hi all,

I'm trying to send alerts via email.

This is the configuration that I added to elasticsearch.yml

```
xpack.notification.email.account:
    exchange_account:
        profile: outlook
        email_defaults:
            from: email@company.com
        smtp:
            auth: true
            starttls.enable: true
            host: exchange-server
            port: 25
            user: MyID
            password: xxxx

```

I get always this error in my watch:

```
  "caused_by": {
    "type": "messaging_exception",
    "reason": "Could not convert socket to TLS",
    "caused_by": {
      "type": "s_s_l_handshake_exception",
      "reason": "sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target",
      "caused_by": {
        "type": "validator_exception",
        "reason": "PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target",
        "caused_by": {
          "type": "sun_cert_path_builder_exception",
          "reason": "unable to find valid certification path to requested target"
        }
      }
    }
  }

```

Can anyone help me ?
