Yesterday, while minimized, Outlook generated an error message saying an error occurred, Outlook was closing and a log was created. This happened several more times. Outlook only runs for a few minutes before the error occurs. Rebooted the PC (XP Pro SP1 256meg) with no luck. Ran detect and repair - nothing. Checked with NAV, Adaware, Spybot and PestPatrol for problems - none found. Ran the scanpst with no problems. I checked for new security patches. The Task Manager shows the usual processes running. The PST file is about 70M in size. When Outlook is running, all features are available and functioning. Everything else on the PC is running just fine. I have been unable to find the log file it says is being generated to pinpoint a problem. Any suggestions would be appreciated.
