Frequently Asked Questions
Are there European alternatives to Microsoft 365?
Yes, there are European alternatives to Microsoft 365. Headquarters, hosting, encryption, and compliance are separate facts, so compare features and verify each provider's current privacy, security, and hosting documentation.
Why switch from Microsoft 365 to a European alternative?
