how to use RRR fields in IMO:

open RRR.pst 
Click on one of the folders in the pst. 
views > current view > define view > select 'RRR' or 'copy of RRR'. Select copy button, change name if desired, apply to all folders. Click ok. 

To apply view, view> current view. select the new view you just created. 

If this doesn't work, you can always copy the RRR folders to your pst and rename. I think. :)
