Fogive me for the (probably) inappropriate placement of this question. I have tried many an avenue to have this clarified and have been unable to gain a authoritive and definitive answer to my question so far.
We are about to replace OCS with Lync (not sure of version) and the question has been asked around the funtionality of an enterprise address book. The answers I get from the Tech guys and their managers differ. The main question is around whether there is an offline mode. Obviously things such as pressence will not work offline, however will the contact details i.e. telephone number, title, address etc found in the address book still be available through the lync client while the client is offline?
