The state administration of Schleswig-Holstein has taken an important step towards digital sovereignty: After from a six-month conversion process, the Ministry of Digital Affairs completed the migration of the entire state administration email system from Microsoft Exchange and Outlook to the open source solutions Open-Xchange and Thunderbird in early October.
The digital department is talking about a milestone after completing a huge project that involved migrating over 40.000 inboxes with a total of over 100 million emails and calendar entries. From the Chancellery and ministries to the judiciary and state police and other state authorities – around 30.000 employees are now in the world of free software.
