Hi,

In Odoo (including v15), archiving is not the same as deleting. When you archive a record (users, products, customers, vendors, etc.), it just sets its active field to False, which hides it from all standard menus, searches, and filters. The record and all its history are still there in the database.

Once you find your archived record, just click “Unarchive” (or “Action → Unarchive” in list view). That will set active = True again and bring it back to menus and searches.

In short: archived records in Odoo aren’t gone — they’re just hidden. Use the Archived filter to see them, and then Unarchive to restore.

Hope it helps
