Lync contacts

[StfC]

Hi,

We have purchased a T41S Skype for Business device to test on our Lync 2013 server environment. Logging in works perfectly (user/pin or user/password) but in either way I don't have the possibility to search in the Lync contacts. I only can dial to a number, or search in local contacts on the phone. Is this normal behaviour? Do I have to configure something?

Thanks,
Stefan
