Lync to Skype Connectivity Now Available

Microsoft have recently announced that Lync to Skype connectivity is now available. Meaning you can now send IM and make audio calls to Skype users (provided they are logged into Skype using their Microsoft account). Video calling is not yet available unfortunately.

This integration is achieve using your existing Lync to Windows Live PIC (Public IM Connectivity) federation, hence the requirement for the Skype user to be logged in with their Windows Live/Microsoft address.

Once you’ve added the user’s Windows Live/Microsoft address, you can IM them like this:


Then you can place a call, which looks like this from the Skype side:


Once the call is up, it looks like this from the Lync side:


And it looks like any other call in Skype:


Required Server Changes

One thing to note is that Microsoft’s blog post shows an option to add a Skype contact from the “Add a Contact not in My Organisation”. This isn’t in the Lync client by default and requires a change to your environment.

add to contacts

To enable this, you need to remove your existing MSN public provider and create a new Skype provider. You will need CsAdministrator rights to carry out these cmdlets:

Remove-CsPublicProvider -identity MSN
New-CsPublicProvider -ProxyFqdn -VerificationLevel UseSourceVerification -Enabled $true -IconUrl -Identity Skype

Once you’ve run it, it’ll look like this in LSMS:


Once you’ve completed the above and signed out of Lync and back in, you’ll see the option to add a Skype contact under “Add a Contact Not in My Organisation”.

Thanks to the always helpful Jens Trier Rasmussen for this information.

    I cannot get this working with Lync Server 2010 (the edge is deployed correctly and used to have MSN PIC setup fine).

    The URL parameter is not supported in the Lync Server 2010 version of New-CsPublicProvider – should I expect the icon to show up in the Lync client then?

    I tried setting this up today and the IconURL didn’t resolve for me even in a browser, the domain doesn’t seem to exist.

    After trying a few permutations, I found that works, with http and https. If you change the -IconURL parameter to, the Skype icon starts showing up in the Lync client.

    My apologies for the above information, the original URL works fine – the problem was specific to my environment. While the alternative URL does work, it’s not necessary.
