I am sorry if this is really newbish question but....
I am just setting up OCS2007 with Com2007 (completely new to OCS). Everything seems to be working fine but when I log into Communicator 2007 and add a contact it comes up as Prescence unknown for that user.
When I try to send a text message I get
This message was not delivered to <user> due to an error: More details (ID:1003)
I am sure I am just missing something stupid. Any help and explaination would be very much appreciated.
Thank You
