I just installed an OCS 2007 server, moved one user from LCS 2005 and am having a problem connunicating between the moved user and users on LCS 2005.
The LCS 2005 client is using OC 2005 TCP
The OCS 2007 clinet is usin OC 2005 TLS
I can start communication from the 2007 user, the 2005 users receives the chat and replies. The reply opens a new OC client. When the 2007 user types in the new window that just opened it fails to deliver. I can go to the original OC window and keep communicating just fine. Each reply continues to open new OC windows.
I have installed a cert on the 2005 server and changed th 2005 user from TCP to TLS but the same thing still happens.
Shouldn't there be backwards compatability?
I have read that that LCS 2005 should be SP1 & have KB921543 & KB911996 but I am not sure how to tell if any are installed. I do not see them in Add/Remove programs. Could this be the problem?
