This article discusses the configuration steps and requirements to integrate Exchange Online in Office 365 (with or without an on-premises Exchange Server 2013 deployment in hybrid mode) with Lync Server 2013, Skype for Business Online (formerly Lync Online) in Office 365, or a hybrid combination of both. The following user configurations are considered in this article:
- A user mailbox on Exchange Online integrated with Skype for Business Online
- A user mailbox on Exchange Online integrated with Lync Server 2013 on-premises
- In this configuration, directory synchronization isn't required. However, we recommend it.
- This configuration is partly supported. See the "More Information" section.
- A user mailbox on Exchange Online integrated with Skype for Business 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.
Through integration with Exchange Server 2013, you can provide the following features to your Lync users. However, some features depend on certain steps being taken and therefore will not work until all the steps are finished. This article highlights the features that will be available after that step is finished.
- Connectivity with Exchange Web Services (EWS) provides the following functionality:
- Outlook integration
- OOF messages
- Conversation history
- High resolution contact photos
- Unified contact store
- Outlook Web App instant messaging (IM) and presence.
- Outlook Web App online meeting scheduling.
The following table lists the supported features and configurations for Lync and Exchange integration. For more information about supported Lync hybrid scenarios, go to the following Microsoft TechNet website:
