Hi Michel,You can login on Exchange server and open Exchange Management Shell and enter this command.Besides, can you give more information about your environment? ~ Where are you trying to install Exchange Management Tools? Is it workstation or server? If server, which server is this? ~ MOM 2005 is not required to run Exchange Management Tools so, can you post exact error message here? You can see below article on, how to install management tools.How to Install the Exchange 2007 Management Toolshttp://technet.microsoft.com/en-us/library/bb232090.aspxAmit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

Dear Michel, Thanks for Amit Tanks reply. Exchange Management Shell (EMS) doesnt require MOM agent. You can install Exchange Management Shell on a member server or client such as Windows Vista. Also, please check whether you meet the following conditions: l To perform this procedure, the account you use must be delegated the Exchange Organization Administrator role. l Before installing the Exchange management tools, you must first install the necessary prerequisites for Exchange 2007. l Exchange management tools bit version match operating system and process bit version. For example, you can only install 64-bit EMS on computer that has a 64-bit processor and 64-bit operating system. l Installing Exchange 2007 or earlier (or the associated management tools) on a computer that is running Outlook 2007 or earlier is unsupported. Microsoft does not support installing Exchange Server components and Outlook on the same computer http://support.microsoft.com/kb/266418/en-us Exchange 2007 System Requirements http://technet.microsoft.com/en-us/library/aa996719.aspx How to Install Exchange 2007 SP1 Prerequisites on Windows Server 2008 or Windows Vista http://technet.microsoft.com/en-us/library/bb691354.aspx How to Configure Language Settings for Outlook Web Access http://technet.microsoft.com/en-us/library/aa997435.aspx Regards, Rock WangRock Wang MSFT
