AFAICS, the text linked from TFA (in German) only mentions MS Teams/Skype as a generic example of a service of a company that, while having an office/subsidiary in EU, does provide fullfillment via its US-based head company, with the general risks associated with US jurisdiction wrt data protection and other legal matters. I don't see how that gives rise to MS sueing the Berlin data protection authority. FWIW, the Mozilla Foundation a couple weeks back, at the height of coronavirus-induced demand for video conferencing, published recommendations for video conference providers here [1], giving MS a pass but not specifically addressing non-US users even though published in multiple languages, including German.
