I got the iPad from work when it was replaced after going out of service after 3 years. I had my apple account set on it, but initially it was activated with the work address. Now it's under "Activation lock" unless I input my old address and password.

It says "This iPad is linked to an Apple ID. Enter the Apple ID and password used to set up this iPad"

Obviously I don't have the receipt.
