If I let user use outlook to send receive email, will the emails show up in Contacts and Leads

Hi,
We currently do not let our users use Outlook. We use the feature in Zoho for Leads and Contacts to view the emails sent or received by our users form the Email section under Leads or Contacts.

If I let them use the Outlook plug in, will the emails they send and receive to leads and contact form Outlook be added, stored, and available for review from inside the email section of Leads and Contacts in Zoho?

Thanks
Steve
