Like most applications Outlook 2002 (from Office XP) will normally minimize to the taskbar. This tweak changes the default behaviour so that it will minimize to the system tray (next to the clock) instead.
1.Open your registry (Click on Start->Run and type regedit and press OK) and find the key below. You may need to create the key if it does not already exist.
2.Create a new DWORD value, or modify the existing value, called 'MinToTray' and edit the value according to the settings below.
3.Exit your registry, you may need to restart or log out of Windows for the change to take effect.
Value Name: MinToTray
Data Type: REG_DWORD (DWORD Value)
Value Data: (1 = System Tray, 0 = Taskbar)
Note: Backup your registry before you try this tweak or any other tweak that makes use of the registry. Changing the values in the registry might cause serious problems.
If you want to minimize more programs to the system tray, take a look at the program PowerMenu. Its a program that runs and allows you to right-click and minimize almost any program to the system tray. It really comes in handy.
