They need to allow it on their end as well. Talk with the admins on the other side, make sure they have added your domain.

You need to coordinate federation between both parties. They need to add your company as a federated partner and you need to add them as a federated partner.

Since you are talking Lync Online, it also depends on which plan you have as to whether or not federation is enabled or available.
