All log files from the user chats are located in:

\\Gw\GWDATA\NOVELL\NM\aa\store

If i take a look in this folder, i see only two files (40221F81, 40221F81.
MAI) and another folder named QFIDX.

Its possible to delete chat logs between 1-2 people or not?

I made two different policies. The first policy log all from 99% of my
users and the second dont log from the last 1%. The members from policy 2
are not member from policy one, but if i take a look in the archiv, i see
the chats. What do i wrong?
