Integrate OWA 2010 and Lync IM

Last few days, I have configured Echange 2010 Outlook Web App (OWA) to integrate the Instant Messaging (IM) of Lync Server 2010.

The objective is to enable communication such as chat with Lync Client and OWA Instant Messaging.

You can also refer this link below:

I also want to demonstrate on how I configure.

On Your Exchange Client Access Server, do the following things below:

  1. Install the Unified Communication Managed API 2.0 Core Runtime (64 bit) in your Exchange Client Access Server (CAS). Click this URL link: http://www.microsoft.com/en-us/download/details.aspx?id=4705
  2. On your Exchange Client Access Server, download the Microsoft Office Communication Server 2010 R2 Web Service Provider. click the link http://www.microsoft.com/en-us/download/details.aspx?id=2310 . Then, it run the file CWAOWASSPMain.msi and it will extract the files.
  3. Go to the folder that you’ve extracted the files and run CWAOWASSP.msi
  4. Download again the hotfix of OCS 2007 R2 Web Service Provider Hotfix KB961256 (http://www.microsoft.com/en-us/download/details.aspx?id=797) and install it in the CAS Server.
  5. Download and install the hotfix Unified Communication Managed API 2.0 Redist Hotfix KB 2647091 (http://www.microsoft.com/en-us/download/details.aspx?id=7557)
  6. Once you have done that, Open the Exchange Management Shell
  7. Run the command Get-ExchangeCertificate  |fl Services, Thumbprint . Copy the thumbprint
  8. Run Get-OWAVirtualDirectory. Please make sure the OWA is currently configured with certificate.
  9. Then run again Get-OWAVirtualDirectory and Set-OWAVirtualDirectory using pipeline. Make sure the thumbprint that you’ve copied is pasted on the command like below: 
  10. While no error is prompted, you type iisreset to restart the IIS service. 

On Your Lync Server, please do the following below:

  1. Open Up Lync Server Topology Builder on the lync server and choose to Download Topology from existing deployment. Then save the tbxml file.
  2. Expand the site, and go to Trusted Application Pool.
  3. Right-click and create New Trusted Application Pool. in the FQDN column, type your exchange FQDN and choose Single Computer Pool. click Next.
  4. Select the Next Hop Pool and site name of the Lync Server 
  5. Then, right click the Site and Publish the Topology.
  6. Open Lync Management Shell and run the command below. “New-CsTrustedApplication -ApplicationId OWAID -TrustedApplicationPoolFQDN net-ex01.netoverme.info -Port 5059”.
  7. Run this comman Enable-CsTopology

Verify the successful Configuration

To verify the successful Configuration that you have done above, simply open your Outlook Web App (OWA) and you will see IM integration as the screen shot below:

Troubleshoot the Problem

From my first configuration, I admit that the IM integration is not working well and the contact of IM in unavailable. So I run the Lync Server Logging Tool and monitor the log.

Here is what I found on SIP Stack.

I went through the Social TechNet Forum and search for the solution. I search through the similar problem and the solution is the SSL Certificate. Then I reissue the SSL certificate of OWA and assigned back to the OWA IIS and reconfigured the OWA using Powershell.

Finally the IM Integration works well.
