CRM for outlook 2015 add email to case.

Hi,

I have an issue with CRM for Outlook.

When trying to add an email to a case through the outlook client nothing happens. It works with other entities. I have tried this using CRM for Outlook 2015, and CRM for Outlook 2013.

Steps to taken:

-Connect outlook to CRM 2015.

-Go to cases.
-Go to the "Add" tab.
-Select a case.
-Click the "Email" button.
-Nothing happens.

Has anyone had this problem before? Any ideas?

Thanks,

Zoe
