 From the Horde FAQ (http://www.horde.org/faq/admin/config/index.php):

4.2.12 Why doesn't the Options button show up in IMP?

[IMP 3.x]: In order for the Options button to show up,
you need to make sure you
have created a preferences storage container. This means
you must have either a
database or LDAP backend in place and configured. For
more information see the
file horde/docs/INSTALL.

You will also have to configure Horde to use the
preferences container. This is done
in the Preference System Settings section of the file
horde/config/horde.php
