Finder: All my Files I have Outlook 2011 installed, and in the finder "all my files" shows me my e-mail messages, contacts and events. Are these Items saved as files on my mac? can I disable this?
The Finders function "All my Files" will show you all files that are saved on your hard drive.

If you delete them they are deleted. How ever, your email could download them again from the email server (like gmail) if you kept them there.
