outlook.pst too big, but cannot reduce

[Mark]

Hi,
A friend is getting the Outlook error saying the outlook.pst file is
too big. They have deleted lots of unwanted emails from the inbox, and
created a new .pst file called archive, and dragged the remaining
emails there. Now the inbox is empty and the archive database is
around 600 MB. They also compacted all their folders. But Outlook is
still saying the outlook.pst file is too big. Any ideas what could be
going on here? Any advice gratefully appreciated.

How big is the PST file in question? Can they open it at all?
