I'm trying what I thought would be a simple import of my 2003 Contact List
into 2007... Is there actually a simple way?
Simplest is with Outlook closed to open the Mail applet in Control Panel,
click Data Files, Add the original Outlook 2003 data file, set it as the
delivery location, remove any other PSTs (except, perhaps, an Archive PST),
then start Outlook. Everything will be exactly as it was in Outlook 2003.
You may have to redefine your mail accounts.
When transferring data from one Outlook to another, never use export/import.
