I have been complaining about a problem I have had with Outlook ever since I installed Zone Alarm Security Suite 6.5 (I am now up to version 6.5.737). The problem occurs usually when my computer is unattended. I have these same versions of ZA on three computers. On one computer I have unchecked the Automatic Send/Receive in Outlook. On this computer I have never had the Outlook must shutdown message. The other two computers are set to check for mail every 5 minutes. These two computers are burdened with the Outlook must shutdown message.
In now believe I know what is causing this problem. When I check for mail Outlook is pinging 3 different POP accounts. If for some reason one of these POP accounts is not responding, Outlook should timeout and check for mail 5 minutes later. When I increased my sever time out to 2 minutes on one POP account the problem seemed to diminish. Yesterday there was some problem on the second POP account which had the timeout set to 1 minute and I received the Outlook must shutdown message.
I now have the timeout for both POP accounts set to 2 minutes and will monitor this.
I consider this a ZA bug that needs to be fixed.
