This problem is not specific to laptops. I’m running Outlook 2003 on a desktop and a laptop at home and a desktop at work running XP (none with an Exchange server), as well as Outlook 2000 on a second machine at work running Windows 2000 (with an Exchange server). All of them have this problem. I do have ActiveSync on two of the machines, but not all. No spyware or browser toolbars on any of them, and the problem started manifesting itself before I installed my anti-virus software. What makes this problem particularly irritating is that it’s intermittent. On all of the machines, Outlook shuts down all the way about 50% of the time with nothing in the systray and no processes running, so I know it has the capacity to properly shut down.
Sorry for just posting another ‘me too’ message. I’ll keep researching and post if I find anything useful. This has been an annoyance since I started using Outlook. As much as I love the new features of 2003, I had hoped that MS would have fixed this.
