Cant view emails from one of my group members in CRM contact

Hi all,

I cant see the emails sent to various contacts, that were sent from one of my members of staff.
The user called Rosana doesnt seem to apear and neither do the mails she sent.
Is she is some way not 'associated' with the crm from her zoho mail account perhaps?
I have attachedd a screen shot...
