From ZoneAlarm

We now have a solution and its ben posted in several area and floated to the top of the boards.

Here is the solution

Some users of free ZoneAlarm have inadvertently had Anti-spam enabled. This can cause interference with Outlook and Outlook Express, or possibly with Outlook crashes.

To turn off the anti-spam filtering, please click on the following link. Select Run. Once it runs, you will get a popup asking if you really wish to add this information to the registry, click Yes. Then REBOOT your system. Antispam should now be disabled.
