I have a trial of OCS 2007 running with about 75 users. Every single one of them can be set up and sign in fine using the 2007 Client.
One user (which happens to be our MD!) cannot sign in, when he tries he is given the error:
"Cannot sign into Communicator because this sign-in address was not found".
Turning on Client Logging I get the following error logged:
"ms-diagnostics: 4005;reason="Destination URI either not enabled for SIP or does not exist";source="cct-moc.hq.
cct""
I understand the meaning of the error, however there is nothing different about his account than anyone elses. People who were set up before him are fine, people I set up after are fine. If I log someone else into his client, they can get in, if I log him into a client elsewhere, same problem.
I have tried everything except recreating his actual AD account, because that seems a little overkill and is obviously fraught with other issues. But removing him and re-adding his OCS settings do nothing.
Really looking for some more in-depth troubleshooting/solutions I can work on please!
