Necessary updates will be installed on the Exchange servers in the upTUdate environment from Tuesday April 21, 2026, 8:30 a.m., until Thursday, April 23, 2026, 5:00 p.m.
Due to the redundant connection of the servers, no service interruptions are expected. However, email clients may briefly lose their connection and may display a login window.
Thank you very much for your understanding and patience during this necessary maintenance work.
