Create Trusted App and Trusted App Endpoint

Open Powershell on the Skype for Business (Lync) Server trusted application server you have previously setup.

You are going to need an unused port number. If you don’t know an unused port number, run “get-csTrustedApplication | ft Identity, port” get to see applications and their associated port numbers that are already in use.

Now run: (replacing red values with your environment specific values)

New-CsTrustedApplication –ApplicationId -Port -TrustedApplicationPoolFqdn

Now we will create an endpoint which you will interact with.

New-CsTrustedApplicationEndpoint -TrustedApplicationPoolFqdn –ApplicationId -SipAddress “” -DisplayName “″

Step for Those Using Lync Server 2013

SEFAUTIL Server has been compiled using the latest UCMA SDK which means that we will need to do a small tweak to force UCMA 4 to be use. In the SEFAUTIL Server code folder look for sefautilserver.exe.config and open the file using Notepad. Insert the below code immediately after the close </startup> tag:&lt;runtime&gt; &lt;assemblyBinding xmlns=&quot;urn:schemas-microsoft-com:asm.v1&quot;&gt; &lt;dependentAssembly&gt; &lt;assemblyIdentity name=&quot;Microsoft.Rtc.Collaboration&quot; publicKeyToken=&quot;31bf3856ad364e35&quot; culture=&quot;neutral&quot; /&gt; &lt;bindingRedirect oldVersion=&quot;0.0.0.0-6.0.0.0&quot; newVersion=&quot;5.0.0.0&quot; /&gt; &lt;/dependentAssembly&gt; &lt;/assemblyBinding&gt; &lt;/runtime&gt;

Install SEFAUTIL Server Application

Download SEFAUTIL Server and run the installer.

Next, (Customer Information) Next, (Destination Folder) Next, (Ready to Install the Program) Next

User Account Control: Yes

Finish

Now Sefautil Server should be running. We can verify using the Task Manager”

: Now we need to exit PowerShell and restart so the new SEFAUtil Server commandlets become available.

Next you will register your copy of the perpetually free SEFAUtil Server Community Edition by running the below command. The system will use Azure to immediately retrieve your key:

Set-SefautilServerRegistration –Name –EmailAddress –PhoneNumber –Implement

: If you have been sent a registration key via email: Set-SefautilServerRegistration –RegistrationKey “”

Below are the new commandlets. See More Details Here.
