Eigentlich hatte ich 13Uhr meinen Feierabend geplant.
Jetzt, 3,5 Überstunden später, ist endlich Schicht. Grund? Das jährliche Hochamt der Microsoft-Lizenzierung. Ein Quell ewiger Freude!
Kosten drücken, Lizenzen jonglieren und beten, dass am Ende niemandem die Funktionalität wegstirbt oder das Kartenhaus kollabiert. Einmal im Jahr immer wieder diese zeitschindende Aufgabe. Wer übernimmt das für mich nächstes Jahr?

Exchange Online Plan 1 licenses generally have a primary mailbox capacity of 50 GB. Exchange Online Plan 2 licenses have a capacity of 100 GB. However, this capacity can be extended by using Online Archive. With Exchange Online Plan 2, this capacity is unlimited. Technically speaking, the capacity is limited to 1.5 TB.
An interesting fact is that Microsoft 365 Business Premium licenses, which by default include Exchange Online Plan 1, are also entitled to this feature.
