I am having problem fetching emails from exchange 2010 pop3, suddenly servicedisk starts fetching emails as request but without mail body and it does not delete the fetched mail from the mail inbox so it always adds the same email as request and without email body, I am forced to delete the email from inbox manually and then the same problem happens with the other email in the inbox, I read the Serverout log file and there is something on the log that says: Problem in process mail content java.io.IOException: error fetching pop3 content.
This problem is resolved when I restart exchange server.
