Mophead, thanks for your answer, but "overwritten" how? During the 2007 installation, Microsoft Outlook was not marked to be installed. Consequently, Outlook 2003 should not be overwritten. Did you mean it was "uninstalled"? I mean, the new whole installation, the pack, overwrote the whole old installation, therefore Outlook 2003 was uninstalled? Is that so?

By the way, she runs Windows XP on her machine.
