Microsoft Outlook is a multi-function program, providing users with email, contact logs, calendars and task tracking. Essentially, Microsoft Outlook and is an all-in-one time-management tool. Some users find its features useful, but others become annoyed with Outlook's pop-up schedule reminders or one-click email access. If you use other methods for scheduling and emailing, you may want to turn off Microsoft Outlook altogether. Simply pressing the red X in the corner doesn't always do the trick, as Outlook processes can run in the background.
Right-click on the Outlook icon if it appears anywhere on your computer's taskbar or system tray notification area. Actively running program icons appear somewhere along this bottom area of the screen for easy access. The Outlook icon appears as a yellow piece of mail with a small clock in front of it.
Select "Exit" or "Close Window" from the options. This usually turns off Outlook completely, but in some cases the program continues to run and you must take further action.
Press the "Ctrl," "Shift" and "Esc" keys simultaneously to open the Task Manager.
Click on the "Processes" tab at the top of the Task Manager. From this tab, you can turn off any lingering Outlook processes.
Scroll through the list and select the process called "outlook.exe." If you do not notice any processes with this label, then Outlook is already completely shut off.
Click "End Process" to shut off Outlook.
