Don't have access to the wallet or account

If he bought coins, and then moved them to a different address (ie. moved them off the exchange)... then the exchange is not going to be able to assist. The fulfilled their part of the deal when the coins where sent.

If they didn't move the coins from the exchange, then they might be able to recover access to the account... providing that the exchange is still functioning and they have access to the same email address used to register.

You could try: https://www.walletexplorer.com/ and see if the address is linked to any of the known exchanges... it's a long shot tho.

I had this bitcoin wallet address 1DBU8EeoJcTNkfjz6hTTjR1RAH3DEzh9YS

But cannot remember the exchange or email i used when i signed up

I'm not sure that is an exchange address... If you look at the list of transactions here: https://www.walletexplorer.com/address/1DBU8EeoJcTNkfjz6hTTjR1RAH3DEzh9YS

You'll find they all end up sending change back to the same address, like this example: https://www.walletexplorer.com/txid/75dffb286896b9a1b86eb49864a22fb32787ddc5ef2e0ddea43f41f42248793d

That is not generally how exchanges work. So, it seems that this was a "single key" wallet... possibly something like an "imported" Electrum wallet, or perhaps MultiBit?
