Enable Skype federation with Skype for Business 2015

One of the very handy features of Skype for business is the ability to federate with the standard Skype network.  This did exist in Lync 2013 but it was kind of clunky.  The federation within Skype for Business is greatly improved.  Below is a guide on how to enable Skype federation with Skype for Business 2015.

First you need to ensure that you have at least one policy set to allow external user access.

Open the Skype for Business Control Panel
Click on “Federation and External access” on the menu to the left
Edit the Global Policy (You can create a new policy if required)
Federation and External Access Global Policy

Tick the box “Enable Communication with public users”
Commit the configuration

Enable communications with public users

 

Now to configure the public provider.

If you have upgraded your Lync 2013 server to Skype for Business you will need to delete the previous public provider.  To do this run the following command from within the Skype for Business Management Shell

Remove-CsPublicProvider -Identity <identity-name>

Replace <identity-name> with the name setup on the old Skype public provider.  This is generally called “Skype”.

To configure the new public provider run the following command from within the Skype for Business Management Shell

New-CsPublicProvider -Identity Skype -ProxyFqdn federation.messenger.msn.com -IconUrl https://images.edge.messenger.live.com/Messenger_16x16.png -NameDecorationRoutingDomain msn.com -NameDecorationExcludedDomainList “msn.com,outlook.com,live.com,hotmail.com” -VerificationLevel UseSourceVerification -Enabled $true -EnableSkypeIdRouting $true -EnableSkypeDirectorySearch $true

Create Skype Public Provider

Now simply restart your Skype for Business client and you will be good to go.
