I have a helpdesk app that will pull helpdesk tickets (in the form of an email) from a mailbox on my Exchange 2003 server. It's been working fine for years and then stopped. The error message I'm getting is:
[6/11/2013 12:20:01 PM] Connecting to POP3 server "servername:110'...
[6/11/2013 12:20:01 PM] Mail server connection error: An operation was attempted on something that is not a socket.
[6/11/2013 12:20:01 PM] End of log
Support for the app said to check out this KB article and I have followed the steps but it did not fix it. http://support.microsoft.com/kb/817571
Any ideas? I have also tried to create an Outlook profile on the server and use that to connect to the mailbox and pull the tickets in but I get the same error.
