This tool does a couple of additional tasks other than just the regular administrative tasks that you can do via Exchange System Manager (ESM):
1. Determine which Exchange Stores in the entire Exchange organization have a Full-Text Index associated with them.
2. Get the status of any existing Full-Text Indexes on a specified Exchange Server. This status information goes beyond what is displayed in Exchange System Manager to include such things as the file locations and whether or not the index is enabled for searching.
3. Detect and repair any known misconfigurations on a Full-Text Index a) Index location path stated in ESM is not correct. b) Crawl seed no longer correct due to either the Domain being renamed or a change to the Primary SMTP Address for the Default Recipient Policy.
