Lync Mac 2011 not connecting

We are using Lync in a secondary college through the Education Department's Mail exchange. The PC's on the network all work seamlessly, but a Mac running OSX 10.7.4 will not connect, failing with the message "Sign in to Microsoft Lync failed because the service is not available or you may not be connected to the Internet". The Internet works on the machine and so does e-mail through the Exchange Server. The Lync server is set to automatic as are all the PC's. Any ideas?

You might have a look at this thread. Make sure you are using the latest Lync client. Apparenly the one that came with Office 2011 would not work, but an update has been posted.

I have tried the above. Installed the latest Lync and tried adding the server addresses, (sipdir.online.lync.com:443) to both internal and external. Also tried with just the internal and just the external. Same result all the time.
Is the address global, or would it be different in Australia?

Hi jackd1,

Are you able to telnet on the 443 ports from this client .I suggest to enable logging on the client and check the logs.

BR,

Sorry I haven't checked back for a while. I've been on holidays. I can telnet on port 80 but not 443. Which logs should I be checking?

Can you go here and test your Lync server's configuration? Check the Lync autodiscovery and other settings, it will help you shed light on what is wrong...
