Error with outlook 2007 0x800CCC0F : The connection to the server was

I am running Outlook 2007 enterprise on Windows 7. I am getting an error when trying to send mail. I can receive mail and it is okay but not send.

Email server setting and account username and password are all correct.
Incoming is pop.gmx.com
outgoing is mail.gmx.com

The error I'm getting is 0x800CCC0F : The connection to the server was interrupted.

I googled the error and the consensus is that anti visus software or firewall is causing the error so I uninstalled my antivirus and firewall software but no luck

This is getting frustrating Any suggestions would be greatly appreciated please!!!!!!!

SOLVED.

Okay here's what I did in case this helps anyone else.

My ISP is telstraclear so I substituted their smtp settings so instead of mail.gmx.com I used smtp.clear.net.nz

I can't believe I couldn't find this solution on the net!!!

sorry, not solved

just got this from mail-daemon

Your message cannot be delivered to the following recipients:

Recipient address: scott.xxx@gmx.com
Reason: SMTP transmission failure has occurred
Diagnostic code: smtp;550 Message rejected
Remote system: dns;mx1.securemx.biz (TCP|203.97.37.64|44754|203.84.134.2|25) (mx1.securemx.biz ESMTP server ready Wed, 28 Jul 2010 07:59:51 +0000)


so again, any suggestions?

Try setting your SMTP server to smtp.paradise.net.nz (advised in Telstraclear online documentation). Hope it works now :)

no luck =( was returned again. I wish I could just use gmx outgoing mail server mail.gmx.com

Anyone know why I can't or how to fix so I can?

Try running Outlook in safe mode; type outlook.exe /safe into the run box under the Start Orb, then hit Enter.
