Am 14. Oktober 2025 endet der Support f\u00fcr Microsoft Exchange Server 2019. Diese Software ist damit am Ende ihres Lebenszyklus (End of Life oder EOL) angekommen. Ab diesem Datum stellt Microsoft keine Sicherheitsupdates, Fehlerkorrekturen oder neue Funktionen mehr zur Verf\u00fcgung.<\/p>\n\n\n\n

Am 10. Februar ist mit Exchange Server 2019 CU15 das letzte kumulative Update f\u00fcr Exchange Server 2019 erschienen. Besonders wichtig sind dabei die Unterst\u00fctzung von Windows Server 2025 sowie von TLS 1.3. Au\u00dferdem hat das Update Exchange Server 2019 auf die gleiche \u201eCode Base\u201c wie Exchange Server SE gebracht. Diese Software ist der Nachfolger von Exchange Server 2019.<\/p>\n\n\n\n

F\u00fcr Hosting-Kunden von Skyfillers \u00e4ndert sich durch diese Umstellung zun\u00e4chst einmal nichts. Unsere Experten haben schon jetzt die n\u00f6tigen Vorbereitungen f\u00fcr die Umstellung getroffen. Anpassungen auf der Seite der Kunden sind nicht n\u00f6tig. Vielmehr l\u00e4uft die Umstellung komplett im Hintergrund ab.<\/p>\n\n\n\n

F\u00fcr Unternehmen, die selbst noch Exchange Server 2019 einsetzen, ist die Situation hingegen anders. Hier sollten die Verantwortlichen so schnell wie m\u00f6glich daf\u00fcr sorgen, dass die Planungen f\u00fcr eine Umstellung<\/a> auf Exchange Server SE oder auf eine andere L\u00f6sung<\/a> vorangetrieben werden. Unser Team ist schon jetzt t\u00e4glich damit besch\u00e4ftigt, Unternehmen und andere Organisationen rund um dieses Thema zu beraten.<\/p>\n","protected":false},"excerpt":{"rendered":"
