The Microsoft 365 alternative from Switzerland
A Swiss alternative to Microsoft 365: chat, mail, documents, spreadsheets, presentations, Drive and meetings. Managed in Switzerland or deployed on your own infrastructure.
What a Microsoft 365 alternative for businesses needs to cover
A replacement must support the working day, not just open Office files. Your team needs shared documents, mail, calendars, files, communication and meetings with one identity and clear access controls.
Rhaetix brings those tools into one workspace that you can run in Switzerland or on your own infrastructure. Evaluate your essential Microsoft integrations and complex workflows alongside the feature checklist.

Word, Excel, PowerPoint, OneDrive and SharePoint workflows
Collaborative Office tools, file sharing and team documentation in the same workspace. The encryption boundary is stated precisely below rather than hidden behind a suite-wide E2EE claim.
Real-time collaborative documents with comments, tables, images and clean PDF export.
Formulas, charts, filters, validation and live recalculation in the browser.
Collaborative decks with layouts, shapes, charts, speaker notes and presenter view.
Files, previews, versions and sharing that follows workspace and channel membership.
Structured handbooks and project documentation linked to channels. Review complex SharePoint sites, workflows and permissions before migrating.
Outlook, Exchange and Teams counterparts
Mail, shared calendars, encrypted team messaging and video meetings are part of the same workspace, not separate add-ons.
Business email with folders, labels, search and rich replies over JMAP, with standard mail protocols for existing clients.
Shared calendars, availability and meeting invitations through open calendar standards.
Channels, threads and direct messages with end-to-end encryption by default, built on Matrix.
Channel huddles and scheduled meetings with screen sharing and a self-hostable media path.
Microsoft 365 is a mature suite with deep Excel, Windows, SharePoint and Teams integration. Rhaetix is not a feature-for-feature clone. Macros, add-ins and specialised Microsoft workflows need a migration review. Rhaetix is the stronger fit when Swiss operation, encrypted messaging, open protocols and self-hosting matter most.
Encryption: exactly what is protected
Chat messages and files shared in encrypted channels, plus call signalling, are end-to-end encrypted by default. Messaging keys remain on your devices. Call media is encrypted in transit and relayed by the media server.
Mail, Office documents, Drive files and calendars are encrypted in transit and at rest, but their content is processed or readable server-side. Self-hosting puts that server-side processing under your control.
Data location and provider jurisdiction
A European or Swiss data centre determines where data is stored. It does not by itself determine which laws can reach the provider. Microsoft is headquartered in the United States; Rhaetix is a Swiss company.
Compare the provider, contract, subprocessors and legal requirements together. Your legal and compliance teams should assess your specific obligations rather than rely on a hosting-location label.
Managed in Switzerland or self-hosted
Managed Rhaetix runs in Swiss data centres with updates, monitoring, backups and migration support handled by us. It suits teams that want Swiss operation without running servers.
Self-Hosted Rhaetix runs on your hardware or private cloud. Your team controls the infrastructure, identity integration and server-side processing while we provide deployment and upgrade support.
How switching works
Use a pilot to test the Microsoft workflows your organisation depends on before moving a whole department.
Inventory and pilot
List your users, data, devices, integrations and essential workflows. Start with one team and a representative set of files.
Bring your files
Import existing .docx, .xlsx and .pptx files into Rhaetix. Check complex formatting, formulas, macros and linked documents during the pilot.
Move mail and calendars
Plan accounts, aliases, DNS and calendar migration with your administrator. Open JMAP, IMAP, SMTP and CalDAV standards keep the path portable.
Run both and validate
Move department by department while the existing suite remains available. Verify data, permissions and daily workflows before retiring the old service.
Questions to answer before you switch
Is Rhaetix a complete Microsoft 365 alternative for businesses?
Rhaetix covers chat, mail, calendars, documents, spreadsheets, presentations, files, wiki and meetings in one suite. It does not reproduce every Microsoft feature, add-in or enterprise integration, so start with the workflows your teams actually need.
Can we keep existing Word, Excel and PowerPoint files?
Existing .docx, .xlsx and .pptx files can be imported and converted. Test complex formatting, formulas, macros, add-ins and linked content during the pilot because those areas need particular attention.
Can Rhaetix replace OneDrive and SharePoint?
Drive covers shared files, versions and access through workspace membership. Wiki covers structured team documentation connected to channels. Complex SharePoint sites, custom workflows and permission models need a specific migration review.
Is every part of Rhaetix end-to-end encrypted?
No. Messaging and files in encrypted channels, plus call signalling, use E2EE. Mail, Office documents, Drive and calendars are encrypted in transit and at rest but are server-readable. The security table publishes the full boundary.
