Deleting a client

[TWLaramie]

Can you delete a client out of Meraki that no longer exists. Second question, can you manually add a client with the same name but different MAC Address. 

[Brash · Accepted solution]

There's no simple way to delete clients from the dashboard. However, they will transition out of the dashboard if they haven't been seen in 30 days. You can also give them a 'blocked' policy in the meantime to ensure that they can't access anything if they reappear.

However there was a mention that something like it might be possible leveraging GPDR privacy features

Not sure of manually adding a client with the same name but different MAC (I can't see why it wouldn't work) but you can definitely re-name discovered clients to have the same name.

If your dashboard is based in Europe, you can forge a client by going to Network-wide > Clients, tick a client's box, and click the Forget button on the top left.

You can also pre-configure a client and give it a custom name:
