20Gb + if using the new, default, pst file type of Unicode which is the
default in Outlook 2003 and later
If however you upgraded outlook from a pre 2003 version, then it maybe that
you are still using the old outlook format data file which has the size
limitation.
Within Outlook, select Personal Folders, rt click, propertiesAdvanced
If under format/type it states 97 - 2002 then it is the old format

Can outlook 2007 have mail stores (PST) greater than 2 GB? I have a friend
who keeps all for his business and is pushing the limit. I was told that
Outlook 2007 raised the limit.

Any clarification is appreciated.
