The Office Communications Server Remote Connectivity Analyzer is a web site for IT Administrators to validate and diagnose end-to-end Office Communications Server scenarios. The site simulates multiple Office Communications Server client access scenarios from outside the customer’s infrastructure and reports whether the test was successful. If the test fails, we inform the IT Admin exactly where in the process it failed as well as provide troubleshooting tips on resolving the issue.
In this beta version, the tool provides the following end-to-end tests:
· Office Communications Server Remote Connectivity
· Office Communications Server Remote Connectivity w/AutoDiscover

Using backup and restoration procedures for site disaster recovery as described in the Microsoft Office Communications Server 2007 R2 documentation library topic Backup and Restoration, can entail some downtime for users.
This white paper describes a site resiliency solution for Office Communications Server 2007 R2. The solution includes an Enterprise pool that spans two geographically separate sites. The solution provides a failover mechanism between the two sites to ensure that Office Communications Server functionality such as instant messaging, presence, and conferencing remains available even if one of the sites becomes unavailable.
This white paper is divided into three main sections:
- The Solution section provides an overview of the tested and supported site resiliency solution described in this paper.
- The Test Methodology section describes the testing topology, expected behavior, and test results.
- The Findings and Recommendations section provides practical guidance for deploying your own failover solution.
To successfully follow this paper, you should have a thorough understanding of Office Communications Server 2007 R2 and Windows Server 2008 Failover Clustering.

The authentication protocol that is used by Microsoft Office Communications Server 2007 and its clients has been updated to require a signature in all messages. This includes the first message that carries the challenge response.
The version number of the protocol that is advertised in the challenge response has increased to version 4. Challenge responses that use version 4 of the protocol must contain a signature. The signature is a digest of the identifying headers in the message. The signature is calculated by using the session key.
Client applications that are built by using the Unified Communications Client API SDK must use this update to register and to work with Communications Server 2007. Communications Server 2007 requires the first challenge response message to contain a signature.

The Microsoft Exchange Server Protocols documentation provides detailed technical specifications for Microsoft proprietary protocols (including extensions to industry-standard or other published protocols) in the Microsoft Exchange Server system.
The Microsoft Exchange Server Protocols documentation provides specifications for protocols that are implemented in the Microsoft Exchange Server system software and that are used to communicate with other products.
The documentation is designed to describe each protocol in detail as it is used by the Microsoft Exchange Server system. Each protocol specification documents the technical requirements, limitations, dependencies, and Microsoft-specific protocol behavior.
The documentation also includes a set of companion overview and reference documents that supplement the technical specifications with conceptual background, overviews of inter-protocol relationships and interactions, and technical reference information, such as common data types and error codes.
