oops I double imported to Outlook from OE

[MrsGrey]

I have always used OE, and now need to switch to Outlook. I have somehow managed to import everything twice from OE -- Addresses and messages.  :-[Is there any way i can undo the last import process? I have hunted around but I guess it doesn't cater for such daftness. There are LOTS of messages, so I don't see how I can delete half of them manually... Any ideas, clever people?
Thanks

uninstall/remove outlook, reboot, re-install outlook and
import stuff ONCE...

Even this might not work since the .PST file where messages are stored does not, I believe, get deleted when Outlook is uninstalled.  In other words, the messages might just re-appear upon reinstalling Outlook. So, you could just delete all messages and then start with a fresh import.

yup, seen that before...delete/removing that profile from outlook usually takes
care of that...!!!
