In this guide I will continue the installation of the SQL 2012 Mirroring cluster which I will use for my Lync 2013 High Availability installation.

You can see the first part here


When using an SQL mirroring cluster you will need a witness server – This is how to install that.


The specs for my witness server is:

  • 1 x CPU
  • 4 GB RAM
  • 100 GB Disk
  • Windows Server 2012

Microsoft has found a critical problem in the WebReady Document Viewing and Data Loss Prevention modules of Exchange, which can lead to remote code execution in Exchange.

See the Security Bulletin MS13-061 from Microsoft and download the updates to you favorite Exchange version.




If you have ever seen the dialin page in Lync Server 2013, you might found that it looks terrible in its native format, and especially the formatting around the dial in numbers.

Below is an example (which actually looks okay)

But with a little change to the dialin page it’s actually possible to make it look nice. →']);" class="more-link">Continue reading

If you are going to deploy a High Availability solution which you can use for Lync Server 2013, you will need to deploy a SQL 2012 mirroring cluster.

This is a guide on how to deploy the two primary server SQL 2012 servers.


I have in this example I have created two SQL Servers with these specs:

  • 4 x CPU
  • 16 GB RAM
  • 100 GB System Drive
  • 300 GB Data Drive
  • Windows Server 2012

You could also have 100 GB Log drive.

SQL Server loves performance and you should always place in a fast storage system, and give it a lot of memory.

Below is a powershell cmdlet you can use to enable AD users in an OU for Lync.

Get-CsAdUser -filter {Enabled -ne $True} -OU “OU=Lync Users,DC=exchangepro,DC=dk” | Enable-CsUser -RegistrarPool frontend.exchangepro.local -SipAddressType Emailaddress

In the Lync Server 2013 CU2 update and the July update a new great feature has seen the daylight.

(get the updates here)


So the great new feature is a Q&A manager for Lync meetings.

I often participate in large Lync meetings where someone is making a great presentation with for example powerpoint.

And then sometimes I have questions or the other participants have questions which they write in the chat window, and then the presenter at some point tries to answer all the questions from the chat window, however until now this have not always been a great experience – You will know if you have tried it.

There can be many reasons why Lync cannot contact external contacts. I have put a checklist together on the most common thing you should check to successful connect to federated partners.

Even if you are setting Lync up for the first time or you have done it several times, you might end up making a mistake in the configuration or forget something in the setup.

So use this guide to check if you have configured everything correct – which you might not have, since you are looking at this blog J

1. Topology Builder

Edit properties at the site level and make sure that federation has been enabled in the topology builder. →']);" class="more-link">Continue reading

If you have a domain and you need to exclude it from the Lync address book, the way to do it is with this powershell

Set-CsUserReplicatorConfiguration -Identity global –ADDomainNamingContextList @{remove=”dc=south,dc=exchangepro,dc=dk“}

You can check which domains Lync will replicate users from with: Get-CsUserReplicatorConfiguration

If you at a later time need to add the domain again simple just use the powershell

Set-CsUserReplicatorConfiguration -Identity global –ADDomainNamingContextList @{add=”dc=south,dc=exchangepro,dc=dk“}
