Lync – Exchange 2010 SP1 OWA integration

I just realized I am missing something from my Lync lab deployment: Lync – Exchange 2010 SP1 OWA integration. I will begin by installing the required prerequisites on my Client Access server.

First, I will download and install “OCS 2007 R2 Web Service Provider” http://www.microsoft.com/downloads/details.aspx?familyid=CA107AB1-63C8-4C6A-816D-17961393D2B8&displaylang=en

 The files will be unpacked here:

Let’s now install the files in the required order:

1. vcredist_x64.exe
2. UcmaRedist.msi
3. CWAOWASSP.msi

Time for “Unified Communications Managed API 2.0 Redist (64 Bit) Hotfix KB 2282949” http://www.microsoft.com/download/en/details.aspx?id=7557

…and "OCS 2007 R2 Web Service Provider Hotfix KB 981256" http://www.microsoft.com/download/en/details.aspx?id=797

At this point, just to be sure I have not missed anything, I will run Windows Updates before proceed further. But of course – Visual C++ update…

Now I can proceed with configuration of OWA virtual directory integration. First I need to obtain the thumbprint of my Exchange certificate by running “Get-ExchangeCertificate | fl” form Exchange Management Shell:

 

I will get the Identity of my OWA with the command"Get-OwaVirtualDirectory | fl"

…and use it to construct my command:

Set-OwaVirtualDirectory -Identity "EX\owa (Default Web Site)" -InstantMessagingCertificateThumbprint 8F9D12B0B143689DD34D55B04CB063A418124FA3 -InstantMessagingServerName fe.lynclog.com -InstantMessagingType OCS -InstantMessagingEnabled $True"

Where “EX\owa (Default Web Site)” is the Identity I obtained from the previous command, the Thumbprint is from “Get-ExchangeCertificate | fl” and “fe1.lynclog.com” is my Lync Standard Edition Server.

Lastly, I will restart the IIS with “iisreset” command.

Now, when I run “Get-OwaVirtualDirectory | fl”, the required parameters are set:

Time for Lync Server configuration.  From Lync Management Shell let’s get the SiteId:

…and construct my command to create Trusted Application Pool – “New-CsTrustedApplicationPool -Identity ex.lynclog.com -Registrar fe1.lynclog.com -Site 1 -RequiresReplication $False”

As instructed, I will run “Enable-CsTopology”

Next step – to create New trusted Application. The command will be “New-CsTrustedApplication -ApplicationId ExOwaAccess -TrustedApplicationPoolFqdn ex.lynclog.com -Port 3800” where ApplicationId is a just a name, TrustedApplicationPoolFqdn is the FQDN of the CAS server and Port – an unused port. Lastly, “Enable-CsTopology” as required.

…and test our setup:
