Is there a Lync alternative on a Mac such that I can still use my Microsoft contacts? Note that I desire to keep all my outlook contacts from Lync but simply using a different service to communicate with them. For example, if I could chat with my outlook contacts via iMessages, that would be ideal. However, if there is a 3rd party messaging service which will allow me to chat with outlook contacts, that will be good too.

  • Do you know if you connect to a Lync server hosted by Microsoft or one run internally by your organisation? Commented Mar 24, 2015 at 18:29

I use Adium, there is an extension that lets you connect to Lync servers.

Protocol plugin for Office 365/Lync/OCS

works only with:

A third-party Pidgin/Adium/Miranda/Telepathy plugin for the extended version of SIP/SIMPLE used by various products:

  • Skype for Business
  • Microsoft Office 365
  • Microsoft Business Productivity Online Suite (BPOS)
  • Microsoft Lync Server
  • Microsoft Office Communications Server (OCS 2007/2007 R2)
  • Microsoft Live Communications Server (LCS 2003/2005)

Once you have the Xtra installed, you can add your Lync account as an "Office Communicator" account.

    For me (in September 2015) this Xtra did not work, but using this Adium plugin - and the awesome FAQ and Help pages i got it up and running: sourceforge.net/projects/sipe Commented Sep 17, 2015 at 6:42
  • This plugin recommended by Georg here worked for me as well (Sept 2016) Commented Sep 27, 2016 at 16:48
