German state replaces Microsoft Exchange and Outlook with open-source email
“The German state of Schleswig-Holstein has dumped its government email and calendar systems for open-source software. The six-month migration has replaced Microsoft Exchange and Outlook with Open-Xchange and Mozilla Thunderbird. The transfer covered more than 40,000 mailboxes and over 100 million messages and calendar entries.”
Again, this is not about necessarily having better or flashier functionality (e-mail and calendaring are basically decades old and open standards). It is about digital sovereignty, preventing vendor lock-in, potentially more local economic investment, and not getting locked into annual increases in cost without any end in sight.
All I can say is, be very wary of corporate PR trying to push any organisation into their cloud-owned service. Losing control of your IT is just not a strategy for the long (or short) term.
