New to Dynamics CRM Online - outlook case email subject and to field

Hi,

When we raise a case against a contact/customer in CRM [outlook], if I click "email" on the "add" menu at the top it opens a tracked email but the TO and SUBJECT fields aren't populated?

This seems odd... Anyway, is there a way to have these populated with the customer/contact email address and populate the subject with the case ID and/or title?

Thanks!

Aaron
