External information from Paul Collins:

• "Microsoft Office Startup" is not required to run at start up. Application which launches common MS Office components to help speed up the launch of Office programs. It's somewhat of a resource hog, and some users claim there's no difference with or without it but it usually isn't required. Note - if you make use of the Microsoft Office Shortcut Bar outside an office program this application will need to be enabled for it to show

Important: Some malware camouflage themselves as osa.exe, particularly if they are located in c:\windows or c:\windows\system32 folder. Thus check the osa.exe process on your pc whether it is pest. We recommend Security Task Manager for verifying your computer's security. It is one of the Top Download Picks of 2005 of The Washington Post and PC World.

It makes computer slower. Hence when anyone wants to run eclipse,weblogic,tomcat or any software development,then make it disable.After disableing eclipse or any software will run fast becauseof consuming 0% cpu usage rather than 100% cpu usage.

Gehört zu Office XP und ist absolut harmlos. Beschleunigt den Start von MS Office XP Anwendungen.

Should speed up MS Office startup. Like every "quick launch" tool, if you're not using the related application every given time you boot your System, you probably don't need it: why consume system resources to improve the performance of something you often don't use? It can be safely disabled. To prevent it from running, choose Start, Run, enter "msconfig" (no quotes) in the 'Open' text box, click OK. Select the 'Startup' tab, uncheck the 'Microsoft Office' item (its line has ...\OSA.EXE in the command value). Hit 'OK'.

Not dangerous, but it consumes too much CPU time & slows down OS. It is useless, as well as FINDFAST. Recommendation: disable it.

my office 2003 don´t opens, it says osa.exe error

osa = office shortcut bar

I have run Ofiice applications with and without OSA.exe and there seems to be no performance difference, (Other than freeing the resources it uses - 4MB Mem, 1.5 MB VM, 0% CPU) I have experienced no crashes, hangs or delays without it. If it is using alot of your CPU, it would be advisable to scan the file for mal-ware.

Win XP, SP2, Office 2003. With osa.exe disabled, C:\Program Files\Common Files\Microsoft Shared\Source Engine\ose.exe does not initiate, which disallows windows update "Update for Outlook 2003 Junk Email Filter (KB925534)" from installing succesfully. Be mindfull of this when choosing whether or not you will disable osa.exe. Link to simple way to enable OSE from command prompt:

Useless resource-hog. I deleted it altogether.
  Veronica  

i was reading this and i clicked the "end task" button and my comps CPU usage went from 99-100% down to 5% then 1%, that might just be my comp but i doubt it, ctrl+alt+delete, processes, highlight it, then click end task

hangs the computer at shutdown

Logging in and running office are faster after I removed the shortcut from the programs- startup folder. I guess it's only good at hogging CPU since office runs better without it. The shortcut was called something like "microsoft office."
