I just created a new dummy user in my Office 365 E3-Plan. When I login for the first time with this dummy user, a welcome screen is shown. It looks like the following screenshot. For all the pages of this kind of wizard, I would like to suggest to add a dot at the end of the sentence.
On the second page, there is a translation issue. It should be Dokumenten instead of Dokumente.
On the last page, there is an untranslated or unused placeholder.
