We have OCS 2007 R2 in my client's organization. They are only using Front End servers (no Director), and we have had no issues with ~5000 users.
We are using Office Communicator 2007 R2 Version 3.5.6907.221. No issues, except *one* user whose status always shows as "Away".
I see nothing in the event logs, and we tried resetting free/busy using Outlook 2007 command line options. I don't see anything in the server logs or local computer logs. I looked at his Communicator diag logs and didn't see anything of note.
Any suggestions are welcome.
Regards,
Paul
