Good afternoon,

Recently, I started to work with Odoo 11, community version.  I've been doing some test and see how this program work and in the test data base everything was ok, so i started to work in the final data base. However, in this new data base when i try to send an invoice by email, I cant. There is the following error:

Odoo Server Error - Access error
The operation could not be completed due to security restrictions. Contact your system administrator.

(Type of document: Message Notifications, Operation: write)

I tried everything, I compare with the test data base and all the data and user are the same and have the same permissions.

Can anyone help me?

Best regards
