Email Service, Learning Platform and Unified User Identities – Bremerhaven Digitizes School IT

As a media center in Bremerhaven, we support a total of about 40 schools, 1,700 teachers and 17,000 pupils in the use of IT and other media. When we began implementing our digitization strategy in early 2015, the introduction of a learning management solution was at the top of our list of priorities. But even then, we were already considering offering further services, such as a service e-mail address for teachers. At that time, however, there was still no standardized database in which the data of all pupils and teachers was available to which a learning management solution or a e-mail server could be connected.
