Cannot Authenticate
Hello,
We have a MS Exchange 2007 server running. In addtion we have another server in the same domain that runs the Web Help Desk (www.webhelpdesk.com) software. This software connects to an e-mail account on the Exchange server and downloads messages every few minutes.
This has been working fine. We have an e-mail account called 'itsupport' and all e-mails sent to itsupport@domain.com and put into the help desk for technicians to deal with.
It has been set up as a POP3 connection using port 995. This has been running well for almost a year until a recently the help desk software stopped downloading the messages.
It does not seem to be authenticating with the Exchange server anymore.
I either get an error message of 'Authentication Failed' from the help desk if I set the port to 110 or an error of 'Unrecognized SSL message, plaintext connection?' if I set the port to 995.
We do have the POP3 service running on Exchange.
I have also tried connecting to an account using POP3 in Outlook but also get an error:
Log onto incoming mail server (POP3): The operation timed out waiting for a response from the receiving (POP) server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP). The server responded: -ERR Command is not valid in this state.
Any ideas?

Did you recently update or change your Certificate on Exchange?

No however I did notice that the certificate that the server generated itself has expired. The certificate has the same name as the server.
Do you think this is the problem? How would I rectify it? There is a mail.domain.com certificate installed as well but the other has expired recently.

Yes. You have to have a valid Certificate for all this to work correctly. Is there a reason you have not installed a Public Key Certificate? Exchange 2007 requires a special Certificate that supports Multiple Domains (UCC) also know as Subject Alternate Names. On a standard installation with only one public Domain Name you will actually have about five dn entries in the Certificate.
I have found GoDaddy offers the easiest solution for obtaining this special Certificate, and the cheapest.

Can I just install certificate services and issue a certificate?
External clients are accessing the mail fine it's just for the help desk software using POP3.

Certificate Services is already there (setup with Exchange 2007) you can create a new certificate.
