My desktop PC, which ran Windows XP Pro SP 2, has died and with it MS Office and Outlook. I have treated myself to a new laptop, running Windows Vista Home, with Mozilla Thunderbird. The installation disk from my PC won't install MS Office on my laptop. I have a fairly recent backup of my Outlook pst files but how do I import them into Mozilla? Mozilla won't do it unless you also have Outlook installed, are there any 3rd party applications that will do the job?
