Hello,
I would like to delete incoming messages from my inbox in Odoo 12. In case of deleting a message, which was usually addressed to me, I get the following error message:
The requested operation cannot be completed due to security restrictions. Please contact your system administrator.
(Document type: Message, Operation: unlink) - (Records: [7241], User: 6)
I don't see any restrictions in the database records, nor do I get more detailed information from the log.
Any ideas?
