BES 5.0.3 and Lync 2010 Integration

With the release of Service Pack 3 for Blackberry Enterprise Server RIM now supports Lync 2010. After searching online i found that there was very little documentation for getting this working properly so i decided to post some information on the steps that worked for me.

I am working with a BES 5.0.3 MR4 (Bundle 107) on Windows 2003 x64Bit server and Lync 2010 is running on Windows 2008 R2 SP1. The Enterprise Messenger client we tried was 2.5.56. Our BES environment was already pointing to a OCS 2007 server and i just needed to point it to the Lync 2010 frontend server. To accomplish this task use the original install files for BES and rerun the setup,but before running the setup a few prerequisites need to be performed. First add the Blackberry Service account to the "RTCUniversalServerAdmins" group. Next install the OCS Core Components on the BES Server. Finally install Unified Communications Managed API 2.0 Download Here. Now run the install and on the "Instant Messaging Settings" screen select "Microsoft Lync Server 2010" and i accepted the default ports as 5061 & 443. Once the setup is finished reboot the BES server.
