Just a heads up.
(in case this has been posted elsewhere, I’m sorry)
We experienced issues with ‘unconventional’ families and naming in Office 365 that is a step back from prior versions of Microsoft Office.
For example, calling the Italic Kursiv, will lead to double slant, when opening a MacOS Word 365 document in Windows Word 365. We fixed this with Default Style Name Italic, Localised Style Name: Kursiv.
Another issue; the Bold won’t show up and be replaced with Calibri, when it is not linked to Regular, but Light or Medium. I will report theses things to Microsoft.
