Odoo 12 : Incoming Mail route to user alias not working

Question

• Configure the Incoming mail Server
• Creating Alias :

Name	alias@domain.com
Aliased Model	Users
Record Thread ID	(ID of the user you wish to assign this alias to)
Default Values	{} (default)
Alias Contact Security	Everyone (default)
Owner	Administrator
Parent Model	Users
Parent Record Thread ID	(same as Record Thread ID)

• Add Alias to user : User -> Preferences -> Messaging and Social :
  • Notification Management : Handle in Odoo
  • Select the Alias

While testing the configuration, no mails are received by the system. 

The mail does not arrive to Odoo. When I check the logs I see the following error:

ValueError: Mailbox unavailable - model res.users does not accept document update

Any idea ?

This is not working anymore since Odoo V12.
