Skype for Business Mac Download Link:


For the best Mac client experiences and an always up-to-date infrastructure, we recommend all customers migrate to Office 365. Skype for Business Server 2015 customers should at a minimum download and install the Skype for Business Server 2015 Cumulative Update version 9319.272 or higher (coming soon). Lync Server 2013 customers should consider upgrading their installation to Skype for Business Server 2015 or downloading the latest Lync Server 2013 Cumulative Update version 8308.973 or higher (coming soon). Lync Server 2010 is not supported – instead, we recommend customers continue to use the Lync for Mac 2011 client.

Two questions….When will screen sharing be available when you aren’t in a conference call? It gave me an error this morning when someone tried to share their screen one on one with me.

Second question, the calendar tab is not displaying anything, is there something I need to setup? We are Office 365 for Exchange. It prompts me every once in a while that it doesn’t have the correct credentials, but this had been working on the Lync 2011 Mac client with the same credentials I’m using now.

    Screen sharing isn’t in P2P calls today, but it does work once you are in a conference (3 people or more in the call), odd that didn’t work for you?

    If you have Exchange Online I believe the calendar tab should populate. Are you seeing that on one machine/user or lots? Might be worth raising a ticket on Microsoft.
