Outlook 2007 not sending/receiving

I have a laptop with office 2007, outlook suddenly stoped sending & receiving mails, I have checked the size of the PST file (Just over 1gb.), I have checked PST files with  the scanpst.exe file, I have created a new profile, and I even have uninstalled and re install outlook, but allways the same outcome.

I know it's not a problem with the server, since I downloaded another mail client (mozilla), and this worked just fine, so I think there's something wrong with outlook.

Any other ideas on what could me wrong with outlook? what else should I check? I also downloaded all available upgrades.

This Laptop is running Windows Vista.

Hello lingtrin,

1. Register an important send/receive library file.  Go to Start > Run and type regsvr32 inetcomm.dll

2. Check if antivirus email check is slowing sending and receiving.  Disable it. Check if other programs running in the background is interfering. Disable one at a time the Firewall, antispyware, antispam, and all Norton programs.

3. In the account settings, Advanced settings, change the server timeout time from 1 min to 5 min

Hope this helps!

I'm so stupid,  bever checked the McAffe firewall, wich was blocking this application, never crossed my mind, how come when there's a problem you never check the most simple solutions? I though that it was a PST problem.

Thanks WAR1
