Standard Exchange Organization Model Detected

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime.

The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine:

  • The number of mailboxes in the organization.

  • The number of routing groups in the organization.

  • The number of Active Directory sites in the organization.

  • The number of Active Directory forests in the organization.

  • Whether Microsoft Identity Integration Server (MIIS) is installed.

The amount for each item determines whether the Exchange organization model is simple, standard, large, or complex. Any organization that is not classified as simple, large, or complex, is automatically classified as a standard Exchange organization.

Of the four defined organizational models for Microsoft Exchange Server 2007, the standard Exchange organization represents the most common topology into which Exchange 2007 is deployed. As messaging service needs grow beyond the resource limits of a single computer, separation of Exchange 2007 services onto multiple computers becomes the next topological division: the standard Exchange organization. The standard Exchange organization builds upon the simple Exchange organization by deploying multiple computers that are running Exchange.
