How can I sync the replies of previous emails from Office 365?

Assume you click on an email and you do not find any lead or contact records in your CRM that match the sender’s email address. Then you can create related Lead or Contact records by clicking the Create Lead or Create Contact buttons.
Here we will explain how to create a contact. The same steps apply to creating a lead.

Follow these steps to create a contact:

1. Log in to your Outlook.
2. Open an email. 
3. Click the Vtiger for Outlook gadget on the top right of the email. The Vtiger CRM pop-up appears on the right.
4. Click the Create Contact button to create the record.
   • Note: During the contact creation, details such as contact names and email addresses are automatically pulled from the email. 
5. Click Save.

The contact will be saved in the CRM.
