Hi Team

I have two CAS NLB and enable POP3 service

one day I restart all CAS Server (No Windows updates). for CAS01 I found POPProxy component state is Active

but at CAS02, I Found POPProxy component state is inactive after server is up. Before Restart happened, all POP Proxy component state is active

is it possible component state become inactive after I restart my CAS server?

can you explain the root cause?

Thanks Team

Hi,

Many reasons may cause this problem, for example Exchange update, temporarily error, please open event log to get more details about this issue.
Please run below command to double check the server component state: Get-ServerComponentstate <Identity>

If the state is Inactive, please run below command to active relevant component:
Set-ServerComponentState <Identity> -Component component name -Requester HealthAPI -State Active
