Sovereign applications · Roadmap

Keep essential communication and scheduling under organisational control.

Bring email, shared mailboxes, calendars, resources, scheduling and organisational contacts into a customer-operated service designed for interoperable, phased adoption.

Status: Roadmap. This application is being developed for open-source release. Its repository, OSI-approved software licence, model-specific terms, version, provenance and supported deployment modes will be published with the applicable release.

Planned replacement scope

Which enterprise software category is this designed to replace?

Roadmap scope: designed to replace or consolidate enterprise email, groupware, shared-mailbox, calendaring, scheduling and contacts platforms. Transition would be validated against delivery, archiving, identity, mobile access, interoperability, continuity and records obligations before legacy services are retired.

Core capabilities

Designed around accountable organisational work.

Exact coverage, deployment requirements and limitations are documented for the selected version and use case.

Organisational email and shared mailboxes

Support individual and functional mailboxes, controlled delegation, distribution groups and policy-based retention.

Calendars and resource scheduling

Coordinate personal and shared calendars, recurring events, availability, rooms and other organisational resources.

Contacts and organisational directory

Use personal and shared address books alongside an authoritative directory governed by organisational identity rules.

Interoperable, phased adoption

Plan coexistence, supported-client access, migration and export around validated operational and records requirements.

Roadmap · Shared application capability

Customer-controlled improvement loop

Planned local analysis of authorised operational signals can propose better routing, scheduling, resource configuration and support guidance under customer-defined evaluation, approval and rollback controls.

Product boundary

Communication connected to governed work

Identity & Access Management controls accounts and access. The Document Management System governs retained attachments and records. AI Assistants can support authorised drafting and scheduling without bypassing approval or retention rules.

Adoption outcome

Treat migration as critical infrastructure change

Begin with representative users and shared resources, test coexistence, delivery, recovery, archiving and export, then expand through an approved transition plan.
