How do I check the email sync settings and edition requirements to view received emails in Contacts?

To check the email sync settings and edition for visibility of received emails in contacts on Vtiger CRM, you need to consider the following:

Email Sync Settings
The visibility of received emails in your CRM can be affected by the Email Sync Settings. For instance, the One Pilot Edition of Vtiger CRM does not support two-way email sync, meaning only sent emails are tracked.

Edition
Ensure you are using an edition that supports two-way email sync to see received emails in your CRM. Different editions of Vtiger CRM have varying features and capabilities, so make sure you are using an edition that supports tracking received emails in the Contacts module. By configuring the appropriate Email Sync Settings and using the right edition of Vtiger CRM, you can ensure that received emails are visible and tracked in the Contacts module of your CRM.
