"Microsoft Outlook's personal folders (*.pst) react quite badly to
oplocks."
This statement got to me. So I created a share on the local drive of
the server and wallah..Outlook can write a .pst file. So it has to do
with doing it over nfs. I could understand this from an OS level, but I
cannot wrap my head around why only outlook? Every other application
works fine.
