Exchange-Mailboxen nach Office 365 migrieren und Parallelbetrieb lokaler Exchange-Server (2) [11.11.2019]

Office 365 spielt in Unternehmen eine immer größere Rolle, auch weil Exchange Server 2013/2016 Hybridumgebungen erlaubt, die Office 365 integrieren. So können Unternehmen auf lokale Exchange-Server setzen, aber dennoch Anwender nach und nach in die Cloud migrieren. Konfiguration und Betrieb solcher Infrastrukturen zeigt dieser Artikel ebenso wie die Migration der Mailboxen und zahlreiche unterstützende Tools. Im zweiten Teil zeigen wir, wie Sie mit dem Hybrid Configuration Wizard Exchange und Office 365 verbinden, Office 365 mit der PowerShell verwalten und eigene Domänen anbinden. [mehr]

Virtualisierung von Exchange Server [19.12.2018]

Exchange Server 2016 ist von Microsoft offiziell für die Virtualisierung freigegeben. Es gibt also Support, wenn Probleme auftreten sollten. Wenn die Virtualisierungs-Hosts entsprechend ausgelegt sind, stehen auch virtuelle Exchange-Server performant zur Verfügung. [mehr]
