Hii,  
I am trying to setup alerting in Kibana. I started elastic cloud instance with GCP as provider, with version 8.4.3 of stack. When I run test connector configuration I am getting below error

 ![error](https://us1.discourse-cdn.com/elastic/original/3X/c/a/cacc8d1e1da8360d42ab8f6c1c74e77700b30638.png)  
I am doing this setup in corporate network and want to send the mail to the receipt inside this network. I guess I have to configure recipients and sender is the Kibana or in the Outlook service which I am using. But did not find any information related this in documentation.  
As I researched, this error is from outlook.
