Unverified paypal accounts are very limited to things you can do with them. Sending and receiving money is one of those things.
The account can easily get limited as well if they notice huge transactions being made to/from that account.
All he has to do is add a CC to it to get it verified and he can send upto 2,500 euros/year with it and withdraw as much as 500 euro/day.
Adding a bank account will remove any limits (available only for USA)
If he can't get a CC for some reason, he can use a VCC. There are some sellers here on MPGH offering that service.
