I have a relatively new Odoo 18 Enterprise database (without activities...) with a whole series of completely unknown email addresses in the contacts (see screenshot: https://www.directupload.eu/file/d/9066/kurcc2jf_png.htm).
Where do these come from?
How can I eliminate these contacts?
When I try to delete them, I get the following message:
Validation Error
The operation cannot be completed: another model requires the record being deleted. If possible, archive it instead.
Model: Sales Order (sale.order)
