I am using Outlook 2003 with Windows XP Pro SP2. Occasionally the system
tray icon remains for Outlook once I close it. It remains there until I
reboot. I do not have the item checked to hide when minimized. Also, if I
close Outlook and the icon remains in the tray, right clicking on the icon
and choosing Open Outlook does not bring up the program. I also check the
task manager and see Outlook.exe listed and when I remove that, the problem
icon disappears.
