How can we see ALL email correspondance for contacts, not just user by user

How can we see ALL email correspondance for contacts, not just user by user

Hi there, 

In the contact view we can see email correspondance with a contact, however it is separated by Zoho user and we cannot see a chronological list of all correspondace, I have to click through each of our users one by one.

How can I set it to simply list all correspondance?

Thanks!

Nick
