After my system crashed, the only way to get it up and running again was to reinstall Windows 7. Then I reinstalled Office 2010. I want to restore all my email messages, folders, contacts, calendar and account information, but I cannot find the *.pst or *.pab containing all my personal data and I had A LOT. I didn't make a recent backup because this was an unplanned reinstallation. Doesn't Outlook 2010 keep these files somewhere? Or when you reinstall does it delete or overwrite all the existing data? I reinstalled it to the same location as it was previously. it shouldn't have just blatantly overwritten or deleted all my previous data. If so, that is unacceptable.
