Top 5 New Lync 2013 PowerShell Features

Microsoft Lync Server 2013 ships with Microsoft PowerShell Version 3.0 which has many improvements to the PowerShell command line interface. Coupled with new additions in the Microsoft Lync PowerShell module, the two bring a lot of great new things to the Lync Administration table. This blog post contains the top 5 things I have discovered so far.

1] The Show-Command CmdLet

The new PowerShell V3 Show-Command cmdlet bridges a bit of the gap between a CLI and GUI interface – which eases some of the syntax-challenges with a CLI interface.

Running this cmdlet opens a small user interface with a list of all available PowerShell modules in your PowerShell session . . . → Read More: Top 5 New Lync 2013 PowerShell Features

Upcoming Restrictions on Public Certificates

A restriction to public certificates was introduced several months ago that could affect your planning of a Microsoft Lync, Exchange, or other application service deployment. While this change restricts only public certificates that contain an internal name with an expiry date after November 2015, you should be aware of this change for planning and certificate renewal purposes.

The Change: No Public Certificates with Internal Names Allowed

In a nutshell, the change will mean that Public Certificate Authorities (e.g. GoDaddy, DigiCert, VeriSign, Entrust, etc..) will no longer issue public certificates that contain an internal only name – i.e. a name that cannot be publicly verified. For Microsoft Lync and Exchange this . . . → Read More: Upcoming Restrictions on Public Certificates

A Primer on Lync Audio Quality Metrics

The topic of audio quality can be vast and complex. The purpose of this post is to provide some practical and easy to read guidance on the key metrics used in several Lync Server monitoring reports. This will enable IT professionals to quickly gain insight into the audio quality of a particular Lync call or conference and troubleshoot poor audio quality if need be.

Note: this post is focused on audio metrics for Lync Audio – not enterprise voice audio – although some of the same metrics apply.

The Lync 2010 Client Audio Codec Selection in Conferences

An update was recently released to knowledge base article 2614343 which describes a Lync 2010 Client update from November 2011. This update enabled the use of the RTAudio narrowband codec for WAN communication to a Lync 2010 Mediation server without the use of Call Admission Control (CAC).

What is more significant about this update (imho), and easily missed, is that this Lync 2010 client update also affects the audio codec selection used by Lync 2010 client during a conference. The change in codec selection during a conference wasn’t previously advertised in the knowledge base article, so it was updated to reflect that. A more detailed description of the change is . . . → Read More: The Lync 2010 Client Audio Codec Selection in Conferences

Customizing the Join Meeting Experience in Lync

Many Lync organizations and users need to customize certain aspects of joining a Lync meeting such as which participants are given the Presenter role, which Lync meeting client a participant will use, or the default text sent in the Lync meeting request.

Controlling who is a Meeting ‘Presenter’

Lync meeting Organizers are often surprised when the meeting starts and all internal participants are listed as a Presenter.

The Presenter role in refers to what this participant is allowed to do in this meeting. Specifically it enables the participant to share their desktop and applications, present files, and manage meeting options including admitting people into the meeting, but it does not . . . → Read More: Customizing the Join Meeting Experience in Lync

Recent Lync Control Panel Issue (AdminUIHost AppCrash)

March 2013 Update: A fix for this issue is now available. See A Fix for the Lync 2010 Control Panel Crash Issue on VMWare for more information.

I have experienced an issue recently with the Lync Control Panel crashing on several Lync servers. It appears the problem is caused by a recent Silverlight 5 update, but may or may not surface on all Lync servers. The issue is being investigated, but in the meantime, if you are experiencing this issue there are two easy workarounds:

Launch the Lync Control Panel from a web browser using the pool FQDN. This will take the form: https://<pool_FQDN>/CSCP. Don’t forget the “s” or a . . . → Read More: Recent Lync Control Panel Issue (AdminUIHost AppCrash)

Tips for Managing Lync User Policies

On-going user management in Lync typically involves changing, deleting, and reassigning existing Lync user policies to specific groups of users to expose or limit features for such things as Conferencing, External Access, and Client capabilities.

When reassigning Lync user policies, you will likely need to select a subset of Lync users based on their current policy and then make follow-on modifications to those Lync user objects. This blog post contains tips on do this and how to properly delete existing user policies.

Finding and Managing Lync Users with an Existing Policy

User policy management in the Lync Server Management Shell will likely involved the use of the Get-CsUser cmdlet. This . . . → Read More: Tips for Managing Lync User Policies
