Germany's infosec office (BSI) reports that 92% of Exchange servers in the country are still operating on software that is no longer supported. This situation follows Microsoft's termination of support for Exchange versions 2016 and 2019 on October 14, 2025, despite prior warnings issued by the company. The findings affect approximately 33,000 public Exchange servers across Germany.
