Provide the ability to create custom User Profile properties using CSOM/REST
Customers usually creates multiple custom User Profile properties. And there is always a need to script this so that it can be repeated across the environments. Today, the only way is to create these using Web UI. This is a huge problem for customers who are dependent on a large number of custom user profile properties.
Thanks for your feedback! Although we appreciate your time and effort to give us this feedback, it’s not something we’re planning to do right now.
We are targeting our API efforts on the Graph API side and due to internal prioritize are not planning to allocate resources to new CSOM capabilities.
