Office Communicator presence unknown.

I have a hosted exchange solution and have recently added OCS to it.  When I add contacts to OCS that are outside of my domain OCS shows them as 'Presence Unknown' and I cannot communicate with them.  The same contacts work fine with Windows Live Messenger.

Of course I have already contacted technical support for my hosting company, but they are of no help.  Is there something I have to change on my end?

Thanks

well, if you want to use OCS to communicate with people on Public IM or on other OCS networks, then you will need the a service called FEDERATION. to do this your gona need an OCS edge server that can not be deployed on the same machine as OCS.
also, federation costs a fee per user (very small some dollers per year per user)

yeah you was mistaken- OCS cant.

out of the box installation will only give you OCS functions within your own network.

since OCS is quiet a comprehensive and heavy application with lotsa features, your gona need to wisely plan your deployment.
OCS can interact with so many hardwaretypes and server functions, that you realy want to plan your structure, or you end up in a total mess, believe me.

here is the OCS deployment guide:
