Zoho Mail - See sent Calendar Invites

Hello, 

When using Zoho Mail and sending a Calendar invite to someone.
We don't see the mail sent with the invite in the sent or trash forder.
This is a pb when the person does not receive the mail for whatever reason.
You can't check the invite sent to troubleshoot or check history. 

Is there any way to see them ?  

Thanks
