Hello, I have problems installing OMA in a new HTPP-virtual server on a Frontend server. I can install OMA in a new HTTP virtual server on a Backend server, that works correct. Using OMA in the "default web site" on a Frontend server also works correct. Installing a new HTTP virtual server with OMA does not work. The errors we see are: from a client: Server Error in '/OMA' Application. Runtime Error from the Frontend-server: Server Error in '/OMA' Application. Directory '\\.\BackOfficeStorage\smtp-domain' does not exist. Failed to start monitoring file changes. Thanks in advance, Peter Kerkhofs
