This webcast includes a brief demonstration on the usage and capabilities of the Microsoft Exchange Troubleshooting Assistant (formerly known as the Microsoft Exchange Server Disaster Recovery Analyzer). This suite of tools is also available in the Microsoft Exchange Server 2007 Management Console toolbox. We provide a walkthrough of the recovery storage group options available from within the tool. We demonstrate setting up a new recovery storage group, adding databases to this it, mounting these databases from within the tool, and merging mailbox contents. Additionally, we show the database repair functionality of the tool, and also include a question and answer session and the chance to provide feedback and suggestions.

Presenters: Chris Gregson, Support Escalation Engineer, Microsoft Corporation, and Mike Hendrickson, Support Escalation Engineer, Microsoft Corporation
