Lync Server 2013 and Lync 2013 can securely and seamlessly communicate with other applications and server products, including Office 2013, Exchange 2013, and SharePoint, if you integrate these products. Integrating Lync Server 2013 and Office provides users with in-context access to the instant messaging (IM), enhanced presence, telephony, and conferencing capabilities of Lync. Office users can access Lync features from within the Outlook 2013 messaging and collaboration client and other Office programs or from a Microsoft SharePoint Server 2010 page. Users can also view a record of Lync conversations in the Outlook Conversation History folder. When integrated with Exchange 2013, Lync Server 2013 also supports the following the following:

Lync Server 2013 supports integration with previous versions of Microsoft Exchange Server and SharePoint, but not all functionality is supported with these previous versions, such as integration of Archiving storage with Microsoft Exchange.

If you are migrating your users to Exchange 2013, you can use both Exchange storage and Lync Server storage on an interim basis, while you complete the migration. Permanent use of both Exchange and Lync Server storage is not supported.

Integration of Lync Server 2013 with Exchange 2013 and SharePoint Server requires server-to-server authentication between servers running Lync Server 2013, Microsoft Exchange Server, and SharePoint Server. Lync Server 2013 supports OAuth (Open Authorization) protocol for server-to-server authentication and authorization. For on-premises server-to-server authentication between two Microsoft servers, there is no need to use a third-party token server. Lync Server 2013, Exchange 2013, and SharePoint have a built-in token server that can be used for authentication purposes with each other. For example, Lync Server 2013 can issue and sign a security token by itself, and use that token when communicating with Exchange 2013. In this case, there is no need to use a third-party token server.

Lync Server 2013 supports the two server-to-server authentication scenarios. These include configuration of server-to-server authentication between the following:

Server-to-server authentication between an on-premises server and an Office 365 component is not supported in this Lync Server 2013 release. Among other things, this means that you cannot set up server-to-server authentication between an on-premises installation of Lync Server 2013 and Microsoft Exchange 365.

For details about server-to-server authentication, see Managing Server-to-Server Authentication (Oauth) and Partner Applications in the Deployment documentation or Operations documentation.
