Sharing photos via Outlook for Mac 2011

I am using iPhoto 11 v 9.1.1 (527) and Microsoft Outlook for Mac 2011 v 14.0.2 (101115). I have Microsoft Entourage selected for "Email photos using" in the General Preferences dialog box (Outlook is not available as a choice).

When I attempt to share photos via Outlook email via:
Share> Email >Compose Message

I get the following error message:

Microsoft Outlook got an error: Can't make {subject:"8 great iPhotos"} into type property of draft window.

Is there some way to make this work so that I can share photos via e-mail using Outlook?

I know I can use the media browser, but that doesn't allow you to add captions, or to control the size of the image.

Thanks, Dave
