I just noticed that my Outlook 2007 pst file is in the old 97-2002 format. I guess that's because it was just copied over when we upgraded several years ago. Is there a fairly easy way to convert it to the newer format? I'm assuming the new format is more reliable, right? Two ways occurred to me: Export everything to the new pst. Create the new pst, make it the default, then import the old one. Is one safer or better? Are there any details I need to make sure to do (or not do) or any caveats?
