On the Exchange servers of the upTUdate environment, a license plan change (installation of Exchange Server Subscription Edition) for Exchange Server 2019 will be carried out between Monday, October 27, 2025, 10:00 a.m. and Friday, October 31, 2025, 5:00 p.m.
Due to the redundant design of the servers, no continuous service interruption is expected. Nevertheless, email clients may briefly lose connection or display a new login window.
Thank you for your understanding and patience during this necessary license change.
