  • 4. Introduction
    Lync Server 2010 can be integrated with Exchange 2010 SP1, so that Exchange Outlook Web App can also act as a Lync web client. Once integrated, users will automatically log into Lync when they log into OWA. The OWA interface changes to include the following new features:
    Sign In and Sign Out - Users can sign in or sign out of instant messaging from OWA. Once signed in, the user will automatically sign into IM every time they sign into OWA.
    Presence - User presence information is available for Lync users, showing a colored Chiclet indicating their availability.
    Contact List - The user's Lync IM contact list is made available in the OWA folder pane. Users can be added and removed, and contact groups can be managed directly from OWA.
    Instant Messaging - Lync users can chat with other Lync users using instant messaging directly from OWA.
    Right-Click Functionality - Right-click menus and actions are updated to include new Lync features. For example, right-click an email address to chat with the user or add them to an IM contact list.

    Exchange Server 2010
    Microsoft Office Communications Server 2007 R2 Web Service Provider from on your Client Access Server.
    Next, download and save the OCS 2007 R2 Web Service Provider Hotfix KB 981256 from
    Download and save the Unified Communications Managed API 2.0 Redist (64 Bit) Hotfix KB 2400399from to the same C:Web Service Provider Installer Package folder.
    If your CAS server is running Exchange 2010 SP1 on Windows Server 2008 R2, you need to download and save the UcmaRedist.msp patch in Microsoft Office Communications Server 2007 R2 Hotfix KB 968802 from The tricky part here is that the file name (UcmaRedist.msp) is the same as the Communications Managed API 2.0 Redist (64 Bit) Hotfix KB 2400399. Just rename this file name to something like UcmaRedist-R2.msp.

    Next configure the Exchange 2010 SP1 Client Access Server for Lync Server integration. Run the following two commands from the Exchange Management Shell on the CAS:

    Get-OWAVirtualDirectory| Set-OWAVirtualDirectory -InstantMessagingType OCS -InstantMessagingEnabled:$true -InstantMessagingCertificateThumbprint $cert
