Overview
By default, Odoo allows multiple partners to share the same email address.
This module adds a uniqueness constraint on res.partner,
so every email in your system belongs to exactly one partner.
No core code is modified - the module uses clean inheritance to apply validation on create and write operations.
Features
- Inherits
res.partnerwithout modifying Odoo core - Validates email uniqueness on every create and write
- Case-insensitive check -
Test@mail.comandtest@mail.comare treated as duplicates - Clear user-friendly validation error on duplicate entry
- Zero configuration required after installation

This email address is already used by another partner.

custom_addonsdirectory - Restart the Odoo server
