Hi, Acccount should be the member of the Delegated Setup management role group or the Organization Management management role group. I recommend you to use the account which you use to install Exchange to uninstall Exchange Server. You can refer to the article below: Install Exchange Server 2010 http://technet.microsoft.com/en-us/library/bb124778.aspx Xiu
