Answer from Microsoft Support:

你的行为看到的是，由于呈现订阅优化到Lync客户端，以便直到必要的联系信息是由Lync客户端所需要的订阅被延迟。照片是这种优化的例子。另一个例子是ContactEndpoints。请看看联系状态订阅变化迁移的部分文档在MSDN文档的Lync 2013页。
具体来说，你必须创建和维护你自己的，你需要的所有ContactEndpoints联系人ContactSubscription。

The behavior you are seeing is due to presence subscription optimization to the Lync client so that the subscription is delayed until the necessary contact information is required by the Lync client. Photo is an example for this optimization. Another example is ContactEndpoints. Please take a look at Contact presence subscription changes section of the Migration doc for Lync 2013 page in MSDN docs. Specifically you must create and maintain your own ContactSubscription for the contacts that you need all the ContactEndpoints.
