OCS 2007 has a PowerPack which enables an administrator to manage a lot of features of the product using PowerGUI. Here it goes..

The OCS 2007 PowerPack provides access to major OCS 2007 Global, User, and Server objects and settings. This includes Users, Edge and Federation, Servers and Global settings. Some objects add links and actions to view further information and to provision and help administer OCS.

This PowerPack was partially based on the OCS Powershell Scripts found in the companion CD of the “Office Communication 2007 Resource Kit” book (http://www.microsoft.com/mspress/books/10482.aspx).

Note: Edge functionality may not work remotely because of a WMI cross-domain security issue.

The MSExchangeTeam released three new documents about Exchange Server 2007, one of them explains how to monitor exchange Server 2007 without using SCOM, as follows:

Ensuring that servers running Microsoft Exchange Server 2007 are operating reliably is a key objective for daily messaging operations. Therefore, ensuring server reliability should be systematically approached based on the principles outlined in Microsoft Operations Framework. For more information about Microsoft Operations Framework, see Microsoft Operations Framework.

A significant aspect of Exchange 2007 daily operations is monitoring the health of the Exchange components to achieve the following goals:

• Generate alerts when operational failures and performance problems are about to occur or do occur.
  
• Represent the health state of servers and server roles.
  
• Generate reports of operational health over time so that you can estimate future demands based on usage patterns and other performance data.
  

For administrators who do not use System Center Operations Manager to monitor their Exchange 2007 environment, a thorough understanding of the most important performance counters and their thresholds is critical to establishing a performance baseline and monitoring plan to proactively monitor your Exchange 2007 environment and troubleshoot and resolve issues when they arise.
