-Two Enterprise consolidated Lync servers in a single pool,
-Two Edge consolidated Lync servers in a single pool,
-One Microsoft Office Web Apps server, and
-One reverse HTTP(S) proxy server. Microsoft Exchange 2010/Microsoft Outlook 2013 are used for internal email and Unified Messaging. The email solution has been used within the company for an extended time without any issues. Unified Messaging has been configured and set
up as part of the Lync 2013 implementation project. You plan to deploy Enterprise Voice for all users, including users who have Lync Phone Edition (LPE) devices that are connected by using a LAN cable and a USB cable. You begin migrating test accounts. When a test user signs into Outlook 2013 and Lync 2013, all communications appear to be working as expected.

The test user enters his credentials and the phone signs into Lync; however, after a short period of time, a yellow warning triangle appears on every test LPE device. In reviewing the LPE device for errors, you discover that Exchange integration is failing with the following error: "Connection to Microsoft Exchange is unavailable. Please contact your support team." Logs from the LPE Device are displayed in the Exhibit 1. (Click the Exhibit button.)
