Mail — Replaces Outlook — **Mail** Replaces **Outlook**

A full mail client — folders, search, rich replies — over open JMAP.

How switching works

Bring your files

Existing Office documents open and convert in the Rhaetix editors; legacy formats are imported on the server.

Move mail and calendars

Mail and calendar run on open standards (JMAP, CalDAV) — established migration paths, no proprietary lock.

Run both during transition

Rhaetix works alongside your current suite while your company moves over, department by department.
