Zoho hosted email for business and Outlook

Zoho hosted email for business and Outlook

Introduction:
We are currently using Zoho CRM and zoho mail add-on.  However, we use outlook to send emails to clients. Currently we can get those emails sent via Outlook back into Zoho if we remember to use the Zoho BCC dropbox.  


My Question:
If we migrate from our current email host to Zoho Mail for all of our email hosting, will we still need to use the Zoho BCC dropbox if we are sending email to clients via MS Outlook.  Or does hosted Zoho Mail automatically tie into the Zoho CRM and flag sent messages to the appropriate lead or contact within ZCRM?

Thank You,

Owen
