Check your Outlook version, if it is sandboxed and compliant with the new Mac OS X security features. See this thread, i.e. the post by Rishi Garrod:
This seems to be a problem with the sandboxing in Mt. Lion. I do not know of any work-around so far, sorry, until a compatible Outlook version will be available.

I've tried deleting ~/Library/Prefernces/com.apple.iPhoto.plist and the lockfile and relaunching. I needed to reset the iPhoto Menu/Prefenences to use Outlook as the mail app of choice but it still does not work. It launches Outlook then does nothing after that?

Thank you for this thread. I'll revert to sending via iPhoto and/or Apple Mail until a Microsoft fix comes out; assuming it is such. There was no discussion of it that I could find on their KB yet though?

No, but it seems to be a similar situations as with Aperture and iPhoto plug-ins, see for example:

Thanks again -I'll poke around http://support.microsoft.com/ph/15627 and post my issue there in hopes there are other 'App sandbox' related concerns. I'm running the most up to date version of Outlook v14.2.4 .... so just may be be a wait for resolve with the next patch. Want to be sure they are aware of it!
