    As I explained in a previous post, the address book component of Lync underwent major changes in Lync Server 2013, but the basic functionality remains the same.  Address Book is a deceivingly simple component.  While how it works is easy to...

    • 0 Comments
    For those of you familiar with the address book from previous versions of Lync, you will find the address book feature in Lync 2013 very familiar. On the outside we have made very few changes. The Powershell cmdlets used to manage the address book are...

    Why is UCMA telling me my session is not established when I add a contact?

    Recently I found myself in the situation where I need to add a contact to a user using UCMA but did not care about what contacts currently existed. I did the standard plumbing to create a CollaborationPlatform and register the user, then added the contact...

    Running UCMA 2.0 applications on Lync Server 2010

    • 0 Comments
    While the most ideal scenario is to only run UCMA 3.0 applications with Lync Server 2010, for many of you this is simply not possible. You may own an application that was written for UCMA 2.0 and you want to upgrade to Lync Server 2010, but the application...

    The Complexity of Simple Urls

    • 0 Comments
    One of the many new features in Lync Server 2010 is a change to how meeting Urls are formatted. The name of this feature is "Simple Url", but in truth this this elicits a smirk from anyone on our team who has dealt with them, as simple Urls are anything...

    Why Get-CsTopology can be evil

    • 0 Comments
    Recently while performing a web search, I came across a blog that recommended that users read the topology Xml returned from Get-CsTopology in order to provision a UCMA application. This is really not a good practice and we actually seriously considered...

    More about manageability changes in Lync Server 2010

    • 0 Comments
    In yesterday's post, I glossed over the small fact that pretty much every single line of manageability code has been rewritten in Lync Server 2010. In today's post, I thought it would be a good idea to explain this further. Almost every single line...

    • 1 Comments
    We are almost at the point where our Powershell commandlet will be useful, but first we need to learn about establishing the session protocol. You see, SIP stands for “Session Initiation Protocol”. The key here is the word “Initiation”. Yup, SIP just...

    UCMA 2.0 - Part 1.5 Setting up a session

    • 0 Comments
    In our next iteration, we will add to our commandlet to create a signaling session. In essence we will send an INVITE to the other party so that we can send a message later. There are a number of steps involved in setting up a session but for now we will...

    Today, we will get started with coding UCMA applications. First though, I would like to cover again the Signaling namespace exposed by UCMA. While much of this is not necessary when using the new Collaboration namespace, I feel that it is still important...

    • 1 Comments
    Before you really start coding in UCMA 2.0, or even UCMA 1.0, it is extremely important that you understand the asynchronous pattern. UCMA is designed for server applications, meaning it supports many operations occurring at the same time. In order to...

    UCMA 2.0 - Part 1.1 - High level architecture and design of UCMA

    • 1 Comments
    Let’s be honest, UCMA 1.0, while very useful, was a bit lame. The frustrating thing about it was it opened up many new possibilities, but didn’t give you the chance to take advantage of them. You could send messages to another party, but could not determine...

    The "new" blog

    In truth, this is now a new blog. I'm not sure what we will be covering in the next several months, short of the already stated UCMA 2.0 APIs. However, there are some sharp differences between this blog and my old one. First, it already has a new look...

    Over the past several months I have come to realize that I needed to change the way I blog. The primary issue is that everything that comes from this blog is often interpreted as coming from Microsoft itself. This has created a number of challenges and...
