The state of Schleswig-Holstein has efficiently migrated its complete public administration e mail infrastructure from Microsoft Change and Outlook to open supply platforms. Over the course of six months, greater than 40,000 mailboxes—holding in extra of 100 million emails and calendar entries—had been transferred to Open-Xchange and Thunderbird, protecting roughly 30,000 staff throughout ministries, judiciary, police and different companies.
Dirk Schröder, the state’s minister for digital affairs, framed the transfer as a pivotal step towards “digital sovereignty”, arguing that it reduces dependence on massive tech corporations and boosts transparency and management over IT infrastructure. Earlier phases of the state’s open supply agenda had rolled out LibreOffice as the usual workplace suite. With the e-mail migration now full, plans are underway to part out Microsoft Workplace totally and change Home windows with open supply working methods corresponding to Linux. The state additionally intends to substitute Microsoft SharePoint with Nextcloud for collaboration and undertake open supply telephony and video conferencing platforms.
The heimliciNor Schleswig-Holstein will not be the primary German state to discover open supply transitions, however the scale and comprehensiveness of this challenge have drawn consideration. Analyses in tech coverage circles now view it as a benchmark for public sector IT reform in Europe. Critics and observers observe that though the targets are formidable, the method has uncovered gaps in planning, stakeholder engagement, and sensible resilience.
Police unions have voiced sharp criticism of the implementation. Torsten Jäger, head of the Schleswig-Holstein department of the German Police Union, described the rollout as “disastrous,” warning that essential data could have been misplaced and asserting that the transition was rushed. In the meantime, senior judicial our bodies raised alarms about disruptions in courtroom operations and subpoenas when e mail entry lagged or failed altogether. In response, Schröder issued formal apologies to employees in a letter, acknowledging that the size and complexity of the migration imposed heavy burdens on customers.
At a session of the Schleswig-Holstein Landtag, the FDP parliamentary group led requires stronger oversight and higher communication from the digital ministry. Lawmakers cited prolonged durations throughout which judges reportedly lacked entry to their mailboxes and police stations that had been successfully lower off from important digital methods. The FDP proposed a movement demanding a extra user-centred strategy, insisting that staff be consulted and totally supported—by way of coaching, interface optimisation and contingency mechanisms.
Proponents argue the state’s daring strategy is now yielding informational returns: having full management over software program stacks allows extra agile adaptation to native wants and safety strengthening. The federal government has already dedicated to sharing its migration instruments and experiences with different states and public establishments, positioning Schleswig-Holstein as a de facto standard-setter in open supply governance.
Nonetheless, technical challenges persist. Customers report latency in mailbox syncing, occasional outages, and hurdles in archiving judicial information in compliance with archival legislation. State officers say a devoted activity pressure has been assembled to observe efficiency, resolve bugs, and stabilise supply. They emphasise that the primary weeks of operation stay a stress check of the system’s robustness.
