Outlook 2010 on Windows 7 will not connect to POP3 unless set to SSL

Hi,

I recently setup two new workstations running Windows 7 32-bit SP1 and Office 2010. I migrated over two users from Windows XP SP3 workstations using Office 2010.

After setting the users up in Outlook, I am unable to connect to the POP3 account, unless I set incoming to SSL. The email provider does not support SSL, so when I set it up this way, I constantly receive an Internet Security Warning "The server you are connected to is using a security certificate that has not been verified" error 0x00000057. Now this makes sense, as the email host does not support SSL and thus does not register a certificate.

Now I am still able to receive emails in this fashoin, with no issues other than the certificate error.

I am not able to connect to POP3 using non-SSL on port 110. I have verified all settings with the email host.

I have gone to a Windows XP machine and setup the same accounts under Outlook 2010 and am able to connect with no issues.

I receive this error when attempting to connect through port 110

"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)." which seems indicative of a blocked port...

On the Windows 7 machine I have tried the following:

Remove and re-add the email account

Uninstall and reinstall Office and reconfigure the email account

Turn off Windows firewall

Attempted to setup a different email account

All of these produce the same problem.

I have an older 64-bit Windows 7 machine and I can setup the email accounts on this box and they work fine. The issue is isolated only to the new 32-bit Windows 7 machines.

The only difference I can think of is the new machines are fully updated using Windows update (including Office updates). However after I uninstalled and reinstaleld Office I did not apply any Office updates, which still did not fix the issue.

Hopefully someone has a few suggestions here.

Thanks.
