I have been hunting around for a while for an easier way to keep my Outlook mail and calendar synced between my Vista and XP installs. Right now my method involves manually exporting my personal folder to a .pst file on a different drive. I have two files in the backup folder, xpversion.pst and vistaversion.pst, so I periodically export a newer version of the file, and import the version from the other OS partition. Is there an easier way to do this?
