IMAP stops working after unexpected shutdown of Exchange

Problem Description : 

IMAP connection for Helpstar stops working after unexpected shutdown of Exchange server

 Resolution : 

The IMAP server component maybe in an inactive state...

Open Exchange Management Shell on CAS1

Run command...

Get-ServerComponentState -Identity cas1

If you see the ImapProxy component in an 'Inactive' state when run the command below to re-activate.

Set-ServerComponentState -Identity cas1 -Component ImapProxy -State Active -Requester HealthAPI

Helpstar email should now start working again after a minute or two.

.....

If the Component state is active for ImapProxy on CAS1 then you may want to also check on mbx1 by running...

Get-ServerComponentState -Identity mbx1

If ImapProxy is inactive then run the set command with the -identity mbx1 to activate.
