Hi Nila,

Email and conferences is the only module you need.

Go to:
System>>settings>>configuration>> Tab:cash and see if "Email and conferences " and External Email is checked.

This can only be done by the administrator of this system.

If you have issues in setting up the e-mail functionality we recommend that a consultant has a look at your system and helps you with it, to make sure everything is in order. Please visit our partner page for a list of partners who could assist with such consulting.
