Export from outlook03 and import in outlook07

No NO NO! this is posted on a daily basis in every Outlook group. Do NOT use
the "import/export" function to move data from one Outlook to another.
Why not?

Importing an entire PST may well corrupt your profile and may create a ghost
PST that you can't close. Importing PST's will lose:
1. Custom Forms
2. Custom Views
3. Connections between contacts and activities
4. Received dates on mail
5. Birthdays and anniversaries in calendar
6. Journal connections
7. Distribution Lists

Opening a PST file will preserve all of these. That is why we do not advise
people to import a native file into Outlook.
