My OL2007 does not download any more messages and the error message includes
this text: "You could also consider using the new Outlook Personal Folders
file (.pst) introduced with OL2004 that provides greater capacity for
storing items and folders"

I am mystified since all my OL data and archives etc. are stored in .pst
files already. So why am I getting this message and what can I do to free up
OL?
