Hi, In my current installation, I couldn't find the Webmailer, FileManager, Calendar, ContentManager modules. Which version of OTRS has these modules and where are these OPM files available in the OTRS installation? As per the admin guide, The package manager can only handle opm packages, other formats (rpm, deb, e.g.) are not supported Thanks N Ramesh This e-mail and any files transmitted with it are for the sole use of the intended recipient(s) and may contain confidential and privileged information.
