Microsoft Lync is one of those fantastic products that I yearn for. It cross cuts the entire communication eco-system and gives you fantastic integration across the Microsoft stack including SharePoint and the Office application suite, however much to my dismay we don’t use Lync in my place of work and instead use the mediocre Cisco CUCM. To this end, my only experiences with Lync in a real-world ‘anger’ situations are when participating in calls hosted by other companies using Lync, Microsoft themselves being the main player for me.

For a long time now, there has been speculation of a Lync Client for Windows Phone 7 being released and this week it finally hit the marketplace not only for Windows Phone 7, but also for Apple iOS devices, Android and Symbian.

The app looks great in the screenshots, showing the features on offer well, however one huge feature is missing for me. The ability to use the app as a Lync Attendee Client: See Lync offers two different clients. The full blown corporate use client and the Lync Attendee Client. If you use Lync in a corporate scenario you will have the full client, however if you are like me and only use Lync to participate in sessions hosted by others, you use the lighter Lync Attendee Client which doesn’t require credentials and is designed around guest access.

Sadly, the Lync Client app for the mobile handsets released this week is only suitable for full client use scenarios as told by the app guidance notes in the Windows Phone Marketplace:

IMPORTANT: Microsoft Lync 2010 for Windows Phone requires a Lync Server or Office365/Lync Online account and will not work without it. If you are unsure about your account status, please contact your IT department.

He being me, I decided to install the app and try it anyway, but sadly the prescribed guidance was correct. This was a sucker-punch to me, and I think it will limit somewhat the ability for people to use the Lync Client. My only hope is that a separate client is released which does give you the ability to participate in Lync sessions as a guest.

If you are lucky enough to use Lync in a full deployment, you can get the app for Windows Phone 7 from http://www.windowsphone.com/en-US/apps/9ce93e51-5b35-e011-854c-00237de2db9e.
