outlook 连接 exchange 2013 RRS feed

  • 问题

  • 大家好,

    环境:同一个域多站点

    DC:2008R2,

    server:exchange 2013 2台 只做DAG 没做cas高可用(两台都是安装CAS+MBX角色安装在cn站点内 名字分别为cnexch01 和cnexch02,cnexch01是处于active状态。)

    情景描述:

    在cn站点内按住outlook ctrl键  发现部分outlook连接到cnexch01部分连接到cnexch02

    问题:

    1.在站点内outlook 会优先通过autodiscovery 到AD找到SCP然后连接到cas服务器,cas角色安装后exchange 默认会自动在ad 站点scp列表里面创建scp对象。scp对象里有优先级。请问为啥有的outlook连接到cnexch01有的是连接到cnexch02.而不是全部连接到cnexch01或者cnexch02?

答案

  • 您好,

    因为outlook 在启动时候就像你提及一样,客户端通过scp记录寻找服务器(http://blogs.technet.com/b/kristinw/archive/2013/04/19/controlling-outlook-autodiscover-behavior.aspx), 因此AD 返回到的SCP 记录会有所不同,同AD 的DC 响应时间有关,所以客户端会根据随机访问得到的SCP记录访问不同的CAS 服务器。

  • 你好,

    SCP的优先级是指SCP进程在查找范围上的定义,并不是针对具体的SCP记录的优先级定义,

    像你这里的两台CAS服务器,在SCP进程查找的时候,优先级是一样的,只是看哪个记录先被检索到,客户端就使用哪个,

    具体的信息,建议你参考下面这篇文章:

    Start with SCP lookup

    Autodiscover endpoints that come from an SCP lookup should have top priority in your list. Administrators can configure SCP objects to route your client to the closest or most efficient Autodiscover endpoint, so it is a good idea to start with these endpoints. Because the SCP lookup process has its own prioritization scheme, the results of an SCP lookup are already prioritized, as follows:

    1. Autodiscover endpoints from SCP objects scoped to the Active Directory site that the client computer belongs to.

    2. Autodiscover endpoints from SCP objects not scoped to any Active Directory site.

    3. Autodiscover endpoints from SCP objects scoped to a different Active Directory site than the site that the client computer belongs to.

    After you have the results of the SCP lookup process, you can add endpoints that derive from the user’s email address. These can serve as a default set of endpoints and a fallback in case there are no SCP results or the endpoints returned from the SCP lookup are not sufficient

    谢谢!
