Hello all,

I have the following setup: (Odoo 16)

I created an Odoo project that creates tasks by sending an e-mail to a certain e-mail address. 

This is working 99% of the time. But sometimes Odoo does not create a task, when an e-mail is send to the certain address. I checked if the e-mail was well received in the inbox of the e-mail account. The e-mail was read, this normally means that Odoo processed the message. 

Is there a way where I can see the E-mail history which has been send to Odoo to this project?

I checked the following places: 

Incoming E-Mail Server ->  (Mail Server) -> Action -> Messages. 
But this place is empty, even though  E-mails are getting processed. 

I tried to find the model for the incoming E-Mails but there is only the model mail.mail, which is for outgoing e-mails. 

The issue is, that I need to prove what happened to the E-mail and why there was no task created. 

Thank you all for your help in advance. 

Michael
