will that combine the old pst and the new pst data, as I've used the new
install of Outlook for a few days.


No - it will open a new personal folders file in your older list. If the
file contains a lot of data, then copy the items from the NEW file to the
old, and in Control panel-Mail-Data Files set the OLD file as the default
delivery location. You can then close the NEW file.
