Question : Overlook in Linux

I've inherited a linux server which looks after email, web cache, internet access and firewall. It had Overlook running on it to access emails from outside the school. However it is now not working. I have no experience in Linux.

Is there a way to check if this is running? What would be the best course of troubleshooting?

Thanks
