Hi,

Actually the problem that you have faced was no more longer in the updated versions of Odoo. Instead of archiving the contact, you can create a custom field to mark the contact as inactive. This way, the contact remains in the system, but you can filter or flag it as needed.

1. Create a custom field 'x_is_inactive' in the customer template.

2. For the contact that is no longer active, set this field to True.

3. Update your views and filters to exclude contacts where 'x_is_inactive' is True.

Thanks.
