Moving from Outlook 2003 to Outlook 2007

1. Transfer emails from Outlook 2003 to Outlook 2007 on new computer

Start Outlook on the old computer. File>Export - follow the Export
Wizard to export your emails (and contact, calendar, notes if desired)
to a .pst file. Save the exported file somewhere you will find it. Now
put the .pst file on whatever media you have that is large enough to
hold it - usb thumbdrive, burned cd-r, dvd-r. Take that media to your
new computer. Copy the .pst file to your User directory; in your
Documents folder is a good choice. You might need to make sure the file
isn't read-only and that you own it. Right-click it and look at its
Properties.

Start Outlook on the new computer. File>Import - follow the Import
Wizard to import the .pst file saved in your Document folder.

For more questions about using Outlook, please post in one of the
Outlook newsgroups such as microsoft.public.outlook or
microsoft.public.outlook.general.
