MS CRM + Auto post on Yammer wall for custom entity

Hello,

We are using MS CRM 2015 Online integrated with Yammer. I have a requirement to post a comment or message on Yammer wall if custom entity status changes and the same time owner of the record should be follower of the post.

As i am new to the Yammer so need some insights here.

-> How to enable post config rule for custom entity to post on Yammer wall.

Thanks in advance.

Regards,

Manish
