Does anyone know how to get hold of the tool called "fbdubfix2.exe" It is mentioned in the article below: http://www.microsoft.com/technet/prodtechnol/exchange/guides/E2k3TechRef/df552c03-a2e9-429f-ac2d-2cc8d26fb4ac.mspx?mfr=true an excerpt from the article: Server-Side Cleaning To clean free/busy data on a server running Exchange Server 2003, a tool named FBDupfix2.exe can be used. FBDupfix2.exe compares free/busy data between different Exchange organizations and marks it as either valid or invalid. I allready contacted dutch microsoft support, but they told me that, if i don't have a MS KB article number the tool doesn't exist. Can anyone help me?
