I like to know how to delete list of users that appers in menu File _ Open
- Other users folders.
As administrative acess some times users request us to delete emails, or
access emails to read.
But historic remains and i like to know how to clean file, without
re-install everthing!

I tried to delete configurations files, and access register, but no sucess.
