Install Exchange 2013 Service Pack 1

Joachim Dissing : 10/03/2014 22:05 : Exchange, Exchange 2013

In this post, I will guide you through the process of installing Exchange 2013 Service Pack 1 on either Windows Server 2012 or Windows Server 2012 R2.

I have in my time as consultant installed a service pack on quite a lot Exchange servers, and before I’m installing a service pack, I also have a “checklist” which much be in place before I start the installation.


So what you need to do, is:

  1. Calculate approx. 1-2 hours for the installation depending on how fast your server is.
  2. Make sure you have a backup, also on your CAS servers. more »

How to handle many SIP Domains

Joachim Dissing : 13/01/2014 23:41 : Lync, Lync Server 2013

I have in the last couple of month’s two customers, who wanted almost as many sip domains as possible in Lync, besides the usual 2-3 sip domains I normally see.


This post is what I found and what I had setup up, at one of the customers.

I found these restrictions:

  • An internal SIP certificate has a limit of 4096 characters.
  • Globalsign (my public cert provider) has a limit of 100 SAN names.

First of all 100 names sub in a public certificate – that will cost a million $ K more »


Use Location Service on a Wired Network

Joachim Dissing : 08/01/2014 23:25 : Lync, Lync Server 2013

As a continuation to my previous post (Use Location Service on Wifi in Lync), I will in this post tell you what is hot and what is not so hot when using location service on a wired network.


So as I my previous post a customer asked me to enable location service in Lync so that the colleagues could locate each other in there fine new building.

Before I started, I might have promised the customer that Location Service was the 8 wonder in world and it was SO cool – I knew only the theory – or most of it K

Back to the customer, which is located in Denmark, Europe – so we can’t use location service for cool stuff like E911 (it’s a wonder that the ambulance can find us J)

Use Location Service on Wifi in Lync

Joachim Dissing : 05/01/2014 13:46 : Lync, Lync Server 2013

Before Christmas, I had a customer, which want to use location service in Lync to display where the users is located within the building.

Because we are located in Denmark, and we don’t have Enhanced 911 or Enhanced 112 as it is called in Europe, the location information is only information to the colleagues.


You can define location service in different ways – by Wifi Access Points, By Switch, Switch port or by Subnets.

I will in this post only show how to define the locations on wifi – but with location service it’s also possible to assign polices which restrict the users bandwidth usage.

Use Web Application Proxy to publish Lync Server 2013

Joachim Dissing : 15/11/2013 01:30 : Lync, Lync Server 2013, Powershell

Windows Server 2012 R2 contains a new feature called Web Application Proxy. WAP is a very simple reverse proxy which can be used to publish the Simple URLs in Lync Server 2013.

In this post, I will guide you through how to setup and use it as a reverse proxy for Lync and the Office Web Apps Server.


I have in my setup defined these public DNS names:

  • Csweb.exchangepro.dk (Frontend Server external name)
  • Cswebapp.exchangepro.dk (Office Web App External name)
  • Cswebdir.exchangepro.dk (Director Server external name)
  • Lyncdiscover.exchangepro.dk (Lync Discover url) more »

Install the Office Web Servers – Part 9

Joachim Dissing : 13/10/2013 22:06 : Exchange 2013, Lync, Lync Server 2013, Powershell

We now have our backend servers up and running and one of the frontend servers, so in this post we will install the two WAC servers in a farm. (see the topology in http://exchangepro.dk/2013/09/21/creating-the-lync-server-2013-ha-topology-part-6/).


The Office Web Apps Servers or WAC is used in Lync Server 2013 for streaming PowerPoint content from Lync meetings to the participates. This means that the participants can see the nice features like animations, sounds, videos that might be inside the presentations.

When a presenter starts a presentation from a Lync meeting the content is uploaded to the Lync FileStore. From there the WAC servers will access the content, and begin to stream the PowerPoint to the participants.

The same WAC servers that we use in Lync can also be used by Exchange 2013 and SharePoint 2013, to provide an web experience for the Office applications. For now, I will only use them for Lync. (but keep coming back and I will show you how to use them with Exchange 2013).

Joachim Dissing : 06/10/2013 20:53 : Lync, Lync Server 2013, Powershell, Windows Server 2012 R2

Windows Server 2012 R2 is soon reaching the GA state, so I decided that I would test how Lync Server 2013 behave on a Windows Server 2012 R2 RTM Server.


So this guide will take you though on how to install Lync Server 2013 on a Windows Server 2012 R2 Server, RTM.

I have created a virtual server in my HyperV lab with these specs:

  • 3 vCPU
  • 8 GB RAM
  • 100 GB Disk space

Install Exchange 2013 on Windows 2012 R2 in a Lab

Joachim Dissing : 01/10/2013 23:09 : Exchange 2013, Windows Server 2012 R2

Windows 2012 R2 reached the RTM state back in august 2013, and is going to be GA on October 18th. 2013.

New software from Microsoft is always exiting and because I love my Exchange very much, and is so lucky to have access to the RTM version from MSDN, I wanted to test if Exchange 2013 CU2 could run on the brand new server platform.


February 2014 Update

With the release of service pack 1 for Exchange 2013, you are now good to go for using Exchange 2013 on Windows Server 2012 R2.

Get Service Pack 1 here


November 2013 Update

CU3 Works fine with the latest updates to Windows Server 2012 R2.


PLEASE NOTE: Microsoft DO NOT support Exchange 2013 on Windows Server 2012 R2 yet – support will come with SP1 which is scheduled to be released in the start of 2014.

Because the support from Microsoft is not there yet, I created a new lab environment to test the installation of Exchange.

The guide is how to install Exchange 2013 CU2 on Windows 2012 R2 (STILL NOT SUPPORTED BY MICROSOFT – so install on your own risk)

Troubleshoot: Presence Unknown on External Contacts

Joachim Dissing : 26/08/2013 23:41 : Lync Server 2010, Lync Server 2013, OCS & Lync

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. more »

Howto Exclude a domain from Lync addressbook

Joachim Dissing : 21/08/2013 09:37 : Lync Server 2013

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“}
