There are a few mailbox.org and tuta.com are both in Germany.

I havent used either but their website leads me to believe they are similar experiences

They are a very very very basic alternative.

Microsoft 365 gives you email, Teams, Office suite, Central AD, Microsoft Windows Licenses, Microsoft Defender, and central device management.

As much as I hate Microsoft, and even though all our company servers run Linux, the mass majority of employees are using Windows, Office Suite, Teams, Defender, and it's all managed through Office365.

Thats microsofts moat- its legacy applications are just part of peoples lvies

i think things like CDNs should be easier to shift
