here is some simple information: Coremail is the first one in china which supports EAI. Coremail has sold many EAI systems, which has supported almost one million users. for example, cnnic's email system have been upgraded to support eai. One of the top email service providers (163.com or neteasy) with around 400 Million users has updated his basic email system to support EAI. In the near future, 163.com will porvide public eai service. So around 1 million users in China has already enjoyed the eai service. So our customer service center normally have the following questions from users: 1, Where can I apply the eai account? 2, why does my email client not support eai? 3, which software does support eai? 4, When will the non-eai email service provider support EAI?

Do you have any statistics you can share?

Many companies and organizations' systems in China have been upgraded to support EAI (The wording Brent suggests. :)). Our customer service centers get many complains about their email clients which can not support EAI. So many customers are waiting for outlook's upgrading to support EAI because outlook are very popular in China and the world.
