【问题描述】
=======================

两台CAS服务器中有一台CAS服务器POP3无法连接。经过测试有问题的CAS服务器:
1telnet 127.0.0.1 110的端口有回显:


2、但是如果连接网卡绑定的IP则连接上没有回显:


3、其它服务都是正常,比如smtp25


【解决方法】
=======================

经过分析造成这个问题的原因,可能Managed AvailabilityMA)对应Componentinactive造成的,需要手动激活:

1.     使用以下命令检查CAS服务器的ServerCommponentstate状态

Get-ServerComponentState -Identity mail01

2.     使用以下命令将State为非Active的组件进行激活:

Set-ServerComponentState -Identity mail01 -Component PopProxy -Requester HealthApi -State Active


3.     再次检查该组件状态:


4.     测试telnet是否正常:
