Is there a difference between MS Outlook and Outlook Express? What are their file extensions? What is the distinction between system tray and quick launch?
Yes, there is a difference between MS Outlook and Outlook Express. The Outlook express is am email client from Microsoft that is built in or integrated with the operating system such as Windows Xp , Windows Vista and Windows 7. The Microsoft Outlook is a program that is included in the Microsoft Office Suite and you cannot install this without buying a license because it is not bundled with the OS.They are both .exe programs used for email clients.They also both supports .eml files.
Quick launch is found in the taskbar that is used for easier launching of frequently used applications. You can add a shortcut of  a program in the quick launch.This will save you time to switch to the desktop to find the icons specially when you have many programs listed. The System tray  or also called as notification area is found in the lower right corner of the screen where you can see the system time and other applications usually running like the antivirus.
Hi,
Both programs are Microsoft Property. I give you properties of both separately so that you can understand better.
1. Outlook Express:Â
2. Ms Outlook:
Now I come to the second part of your query. Quick launch is the area where you are working. It is made for the users so that they can get fast access to any of the program that frequently uses. You can add any program to that area and have fast access to that. Otherwise programs are available in their installed locations.
While notification area is the windows own working area. If something happens it is sent to notification area. All errors, Alerts and software activities can be seen in notification area. Some software also uses to send alerts to notification area.
So both areas are different with different roles in windows.
