The autostart shortcut to OSA.EXE was added while installing Microsoft Outlook 2002.

"What Does the Osa.exe File Do?
The Osa.exe file does the following:
* Initializes automation.
* Initializes some of the common fonts installed by Office XP.
* Handles certain commands (New Office Document, Open Office *Document, Help, and Screen Saver) on the Start menu and on the Office Shortcut Bar.
* Displays Microsoft Outlook notifications when the Office Assistant is available.

What Are the Advantages of Running the Osa.exe File?
The Osa.exe file initializes the shared code that is used by the Office XP programs. When you use the Osa.exe file to initialize shared code, the Office XP programs start faster. If the Office programs, instead of Osa.exe, initialize the shared code, the programs take longer to start."
