I tried using the 8.03.0056 build of Exhange profile analzyer against a 2010 Ex org and am getting "Unsupported Exchange Version: 14.0 ....." Is there a build that supports EX2010? Thanks, Chris

As far as I know that tool is not supported in Exchange 2010 (the main purpose of this tool is to size profiles on exchange 2003 / 2007 before migrating to Ex 2010). You can use PowerShell to get some info about user mailboxesWith kind regards Krystian Zieja http://www.projectnenvision.com Follow me on twitter My Blog

Krystian is right ! See below link for more info http://exchangeserverpro.com/planning-exchange-server-2010-deployment-the-exchange-profile-analyzerAnil http://messagingschool.wordpress.com

It is correct. Servers from which you want to collect statistics must be running one of the following: a. Exchange Server 2007 b. Exchange Server 2003 Service Pack 2 or later Here is more information.
