Exchange 2013 IMAP Cert error.
ok so I have resolved the issue with my exchange 2013 email server. I am trying to get the IMAP to work but everything checks out except for this.
Testing the SSL certificate to make sure it's valid.
The SSL certificate failed one or more certificate validation checks.
Additional Details
Elapsed Time: 323 ms.
Test Steps
The Microsoft Connectivity Analyzer is attempting to obtain the SSL certificate from remote server mail.fitzpro.com on port 993.
The Microsoft Connectivity Analyzer wasn't able to obtain the remote SSL certificate.
Additional Details
The certificate couldn't be validated because SSL negotiation wasn't successful. This could have occurred as a result of a network error or because of a problem with the certificate installation.
Elapsed Time: 298 ms.
I have verified that the cert is good because it works with IIS and Active sync, and SMTP.
anyone had any ideas?

Yeah, you need to buy a third party certificate bro!
Did you apply your certificate to your IIS and IMAP?

I know the cert is good because it all worked just fine before and all of the sudden after some windows updates it broke.
After checking the event logs I located the following error message under the Application logs.
EventID: 1011
Source: MSExchangeIMAP4
Description: The IMAP4 server’s Online status has changed to False.
IMAP4 Event log error
After performing some further research I determined that the IMAP Proxy had stopped on the server. To check this perform the following
Open the Exchange Management Console
Run the following command Get-ServerComponentState -identity Servername
You will notice that the IMAPProxy state is set as inactive
Server Component State
To resolve this issue you must perform the following
Open the Exchange Management Console
Run the following command Set-ServerComponentState -Identity Servername -State Active -Requester HealthAPI -Component ImapProxy
IMAP should now be working again on the Exchange 2013 server.
after I restarted all the component states all is tested and up and working.
