**How to export contacts from Outlook 2003, 2007**
Open Outlook 2007 -> Select File and then Import and Export.
From the list, choose Export to a file and then click Next.
From the list, choose Person Folder file (.pst). I prefer to export it out as a PST file so that it can easily be imported into another Outlook, even of a different version.
Now you’ll get a list of all of your folders, including the Inbox, Calendar, RSS feeds, etc. Click on Contacts as we want to export Outlook contacts only. If you have created other contact folders inside the main contact folder, be sure to check off the Include subfolders box.
Click Next and then choose the location for your backup file. Make sure to browse to some other location as Microsoft defaults to a hidden folder. Click Finish and the contacts export is complete.
