I mistakenly installed Office 2007 last week and I absolutely loathe it, Outlook seems to randomly take up 100% of the CPU usage and I'm getting random error messages in Word and Excel, I'm planning to downgrade back to Office 2003 but I have around 2000+ emails in Outlook which I can't afford to lose as they're for work, I've tried backing up the PST file, uninstalling Office 2007, reinstalling 2003 and importing it but predictably it tells me the PST is for a different version and won't import. Anyone have any ideas?
