Show name details Lotus Notes

I have a user that don’t are able to ‘show name details’ on a #group that he write in the “To” field in a new message.

He sad that this wasn’t a problem on the old mailserver (Domino R7). Now we have Domino 8.0.2 server and Notes 8.0.2 clients.

He have the same ACL as before on the names.nsf on the server.

I as administrator can see name details on a #group
