Hi Peter,
Microsoft lync free download - Lync, Microsoft Teams for Windows 10, Microsoft Lync 2010 (64-Bit), and many more programs. May 10, 2017 Overview Microsoft Lync is the new rich client for Lync users on the Mac platform and offers integrated functionality for instant messaging, presence, conferencing and voice. Lync for Mac is designed to work with both Lync Server 2010 and Lync Online to help you.
I used this solution below and my MBP back to login in my Lync server:

To resolve the 'Sign in to Microsoft Lync failed because the service is not available or you may not be connected to the Internet.' you need to reimport your Lync server certificate.
Ask your system administrator of the Lync server to export the server certificate and provide to you:
- Log into Lync server
- Open MMC > Add/Remove Snap-in > Select Certificates > Click Add > Select Computer account > Click Next > Local computer > Finish > OK
- Expand Certificates > Personal > Certificates Best photo database software mac. Download music from mac app free.
- Click on the certificate with the fully qualified domain name (i.e. Lyncserver.xyz.com) with the intended purpose 'Server Authentication'
- Right click > All Tasks > Export > Next > No, do not export the private key > Select Base-64 encoded X.509 (.CER) > Next > Give it a name (fully qualified domain name) > Next > Finish
Once provided with the .cer file, exit Lync on your Mac, double click the .cer file to import it into your keychain. Once imported, double click the certificate in Keychain and in the Trust section change 'When using this certificate' to 'Always Trust'.
Start Lync back up, and you should be able to log in.
