SUMMARY

This article discusses the configuration steps and requirements to integrate a Microsoft Exchange Server 2013 or Exchange Server 2013 hybrid deployment with Microsoft Lync Server 2013, Microsoft Lync Online in Office 365, or a hybrid combination of both. The following user configurations are considered in this article:
  1. A user mailbox on Microsoft Exchange Server 2013 on-premises integrated with Microsoft Lync Server 2013.
  2. A user mailbox on Exchange Server 2013 on-premises integrated with Microsoft Lync Online.
    • Directory synchronization is required.
    • This configuration is partly supported. See the "More Information" section.
  3. A user mailbox on Exchange Server 2013 on-premises integrated with Lync Online through a Lync Server 2013 hybrid deployment.
    • Directory synchronization and single sign-on (SSO) are required as part of setting up a Lync hybrid deployment.

DEPLOYMENT

  1. Make sure that the Domain Name System (DNS) records for Lync federation and Lync client discovery are always configured so that Microsoft Outlook Web App can determine where the user’s Lync server is located.

    Make sure that DNS records all point to Lync Online. For more information, go to the following Microsoft Knowledge Base article:

    Make sure that DNS records all point to on-premises. For more information, go to the following Microsoft websites:

  2. Make sure that Exchange Online has access to the user’s Lync SIP address. Exchange uses the Active Directory ProxyAddresses attribute to determine the user’s Session Initiation Protocol (SIP) address. If the attribute doesn’t contain the user’s SIP address, Outlook Web App won't be able to connect.

    No additional action is required.

    • Directory synchronization is required for this scenario.
    • Connect to the Exchange Admin Center (EAC), and then add the user’s SIP Address by using the following Microsoft TechNet article for guidance:
      Add or Remove Email Addresses for a Mailbox (http://technet.microsoft.com/en-us/library/bb123794.aspx)
      Note Make sure that the SIP address is added by using the correct format (for example, sip:user@contoso.com, where user@contoso.com represents the email address of the user).

    • Directory synchronization is required for this scenario.
    • No action is necessary beyond implementing DirSync. The msRTCSIP-PrimaryUserAddress attribute is set on-premises and is fully available to Exchange Server 2013.

  3. Make sure that Lync has access to the user’s Exchange email address.

    • Directory synchronization is required for this scenario. Because Lync Online users don’t have a mailbox in the cloud, there's no other way to manually specify the MAIL attribute.

    • Directory synchronization is required for this scenario. Because Lync Online users don’t have a mailbox in the cloud, there's no other way to manually specify the MAIL attribute.
    • Directory synchronization is already a prerequisite for a Lync Server 2013 hybrid deployment.

  4. Add trusted applications. 

    Note This step applies to Exchange Server 2013 or Exchange hybrid customers who are trying to integrate with Lync Server 2013 or Lync hybrid deployments.

    This step isn't possible with Lync Online. This is why some advanced Exchange and Lync integration features are unavailable in this scenario.

    Lync Server 2013 and Exchange Server 2013 must be configured to use OAuth for server to server authentication. For more information, go to the following Microsoft TechNet website:
    Both Lync and Exchange must be added as partner applications. For more information about how to configure Exchange Server 2013 and Lync Server 2013 as partner applications, go to the following Microsoft TechNet website:

  5. Configure the on-premises Outlook Web App virtual directory. The configuration has to include the IM server name and IM type.

    Outlook Web App has to be added as a trusted application to Lync, and the Exchange Server virtual directory for Outlook Web App must be configured by using the correct settings to work with Lync. For more information, go to the following Microsoft TechNet article:

  6. In a Lync hybrid deployment, make sure that the on-premises Lync Server trusts the Office 365 authentication service.
