Email and instant messaging (IM) are both forms of communication that are frequently used in businesses around the world. As workers are becoming more mobile, IT departments are challenged with providing more ways for the mobile workforce to communicate. Now you can integrate Lync 2010 with Exchange 2010 using Outlook Web Access 2010 (OWA 2010), providing users with the ability to see each other’s presence and have Lync IM sessions. This added feature can be a real benefit to the mobile workforce as they can start Lync IM sessions with any device that has a supported browser for OWA 2010 and Internet connection.
The Lync integration with OWA 2010 provides some basic Lync functions and does have limitations on what capabilities are available to use while logged into OWA 2010. Browsers that only support OWA Light version will not have the Lync features available. So for those thinking they can use this to Lync chat on their iPhones – sorry, it won’t work, but there is a Lync iOS app that provides the same capabilities.
The following features are available using Lync 2010 though OWA 2010:
The following Lync 2010 features are NOT available through OWA 2010:
To get started with Lync using OWA 2010 you’ll need to make several changes on your Exchange 2010 Client Access servers (CAS) and the Lync 2010 servers. If you have an array of Exchange 2010 CAS servers you will need to make the modifications across all the servers. You will also need a certificate that is trusted by both the Lync and Exchange servers that contains the CAS namespace on the subject line. Typically you can use the same certificate that you are currently using for your existing OWA 2010 site.
Get-OwaVirtualDirectory | Set-OwaVirtualDirectory -InstantMessagingServerName <name of Lync Server or pool to connect to> -InstantMessagingCertificateThumbprint <certificate thumbprint> -InstantMessagingEnabled $true -InstantMessagingType 1
You will need to create an Outlook Web App pool entry on the Lync Server 2010 server. Using the Lync Server Management Shell complete following steps.
New-CsTrustedApplicationPool -Identity <OwaPoolfqdn same as what is used in SN of cert> -Registrar <OCS Pool Fqdn> -Site <siteId> -RequiresReplication $false
New-CsTrustedApplication -ApplicationId <ApplicationIDForOWA> -TrustedApplicationPoolFqdn < OwaPoolfqdn same as what is used in SN of cert> -Port <some available port>
Once you’ve configured the integration between Lync 2010 and OWA 2010, the users who are already enabled for Lync will start seeing the new enabled feature the next time they login to OWA 2010. Providing these extra features to users gives them different forms of communication to utilize while on the go. Lync integrated with OWA 2010 has its limitations but it does provide basic IM functions for users.
