Where does Outlook 2007 store attachments by default?

This question can have two answers

1. All attachments are stored within their respective emails and emails are stored in personal storage file (PST , your data file)

2. The temporary attachment that you open in an open email is saved in a folder with name similar to “OLKxxxx” (where x may be some number)

This folder is saved in “temporary internet files” folder located in c:\documents and settings\\local settings\temporary internet files
