I have a question and I can't find the answer...

I work for a company (windows) as an external supplier (mac and no network) and they would like to get in contact with me with this lync software. I downloaded it but now i'm a bit lost already in the beginning with the login. what login data do I have to fill out there? where can I register myself? or isn't it possible to use it from the outside of a company?

thanks a lot for your help!

Hi,
Microsoft Lync Server (previously Microsoft Office Communications Server) is an enterprise real-time communications server, providing the infrastructure for enterprise instant messaging and other many communication features. If your company deploy on premise Lync Server or sign up for Office 365 and your account and password should be provided by your company, then you would be able to connect and sign in Lync Server that your company deployed or Office 365 from Microsoft.  It is different with Windows live account which you can sign in Microsoft Message server as Windows live account is designed for personal users.
