I am trying to rename the schema-root folder in \NON_IPM_SUBTREE to coax Exchange into rebuilding the Public Folder structure. (EXOLEDB error in propagating schema). Here is the command-line: Set-PublicFolder -identity "\NON_IPM_SUBTREE\schema-root" -name "schema" The error is "Cannot save the object '\NON_IPM_SUBTREE\schema-root'. Please make sure you have specified the correct Identity and that you have the necessary permissions to save it." I have Enterprise Admin, Schema Admin, Domain Admin, and Exchange Organization Administrators membership. Is there something else I need in order to run this command? This is the problem I am trying to fix: http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=1110224&SiteID=17
