Each time I upgrade to a new version of Outlook (or switch to a new computer), I always configure Outlook to minimize to the System Tray. This way, I do not have the Outlook button on my taskbar, especially given that I have Outlook running for most of the day. When I have several different things open, I feel like it is taking up valuable space on my taskbar.
By creating a new registry entry, as I describe below, Outlook is minimized to the System Tray instead of the Taskbar. You can then maximize the program by double clicking the icon.
To accomplish this: open your Windows registry (type regedit at the run command). Locate the following registry key: HKEY_CURRENT_USER Software Microsoft Office 12.0 Outlook Preferences. Create a new DWORD value by clicking Edit, point to New, and click DWORD value.
Type in MinToTray for the value name. Open the new DWORD value and change the value to ‘1’. Close your registry editor,
