The Small Firm Owner

Weighted verdict

Runs a tax and accounting firm of twelve in Lower Saxony. Every member of staff lives in Outlook, the shared "kanzlei@" mailbox is the busiest address in the office, and the meeting room is booked by shouting across the corridor. Wants mail on the firm's own domain that arrives, a shared calendar and address book on every phone, a move from the old provider that does not lose a single client thread, and a per-user price that is still the price in the second year.

Same scores as the panel view — this lens weights them the way this judge cares.

Mail, domains & deliverability

How this is scored

How well the mailbox itself works: custom domains and their DNS set-up, aliases, catch-all, shared and functional mailboxes, distribution lists, mailbox and attachment size limits, IMAP, POP3, SMTP and Exchange ActiveSync or MAPI for Outlook, web and mobile apps, spam and malware filtering, SPF, DKIM, DMARC and MTA-STS, out-of-office and server-side rules, send limits, and the delivery reputation of the sending infrastructure. A self-hosted groupware is judged on the mail server it ships; a suite whose mail app is only a client for another server scores at the level of that client.

0 — No mailbox at all; a product that only sends transactional mail or only reads another provider's mail without a server of its own or a documented one to pair it with.

3 — Mailboxes on a custom domain with IMAP and SMTP and a webmail; aliases, shared mailboxes, filtering and DKIM or DMARC are basic or not described.

5 — Several custom domains with a documented DNS set-up, aliases and distribution lists, shared or functional mailboxes, IMAP and SMTP plus mobile apps, spam and malware filtering, SPF and DKIM signing, mailbox size per plan stated, server-side rules and out-of-office replies.

8 — Exchange ActiveSync or native Outlook (MAPI) support, DMARC reporting and MTA-STS or DANE, catch-all and plus addressing, delegated access and send-as, quarantine an admin can review, send and attachment limits stated, and the deliverability of the outbound infrastructure documented.

10 — A mail platform a large organisation runs on: every protocol above with feature parity stated per client, inbound and outbound gateways configurable, journaling, DANE and MTA-STS enforced, delivery monitoring and bounce analysis for admins, and mail flow documented end to end.

Report an error

The Small Firm Owner

Custom-domain mail is fully documented with IMAP on port 993 (SSL) and authenticated SMTP on 587 with STARTTLS, SPF, DKIM and DMARC plus anti-spam and anti-virus are stated, and the address model lets several of my staff work one shared mailbox each with their own revocable device password — that is exactly how our kanzlei@ address runs. Send limits (500 E-Mails / 24H paid), a 3 GB attachment ceiling and unlimited mailbox storage on paid plans are published. We found no public information on Exchange ActiveSync or native Outlook (MAPI) access — the documented Outlook set-up runs over IMAP — nor on catch-all, distribution lists, out-of-office replies or server-side rules. 2 3 6 7 13 17 19

Calendar, contacts & office apps

How this is scored

What the office plans and writes with: shared and team calendars, free/busy lookup, meeting invitations across providers, room and resource booking, shared address books and a company directory, CalDAV and CardDAV or ActiveSync for phones, Outlook calendar sync, tasks, online office documents with co-editing, file storage that comes with the suite, video meetings and chat inside the bundle, and the desktop and mobile apps.

0 — Mail only, with no calendar or contacts of any kind.

3 — A personal calendar and address book in the webmail; sharing, resources, sync protocols and office apps are basic or not described.

5 — Shared calendars and address books, meeting invitations with free/busy lookup, CalDAV and CardDAV or ActiveSync sync to phones and desktop clients, a company-wide address book, tasks, and either online office documents or a documented integration with an office suite.

8 — Room and resource booking with approval, delegated calendar access, Outlook calendar and contacts sync documented, co-editing of documents and spreadsheets in the browser, file storage with sharing, video meetings in the bundle, and apps for desktop, iOS and Android.

10 — A full office suite that replaces Microsoft 365 for a whole organisation: every function above with Microsoft file formats edited without loss, scheduling across organisations, resource planning, offline editing, an accessible interface stated against a standard, and feature parity across web, desktop and mobile documented.

Report an error

The Small Firm Owner

CalDAV and CardDAV sync reaches iPhone, Android (via kSync), macOS and Windows Outlook through a documented configuration wizard, meeting rooms can be created with capacity and location, searched for a chosen time slot and carry a shareable calendar each, and OnlyOffice co-edits Word, Excel and PowerPoint formats in the browser with kDrive storage, kMeet video and kChat in the bundle. We found no public information on booking approval workflows, delegated calendar access, a company-wide address book or tasks. 1 2 7 15 16 17

Report an error

Security, encryption & compliance archiving

How this is scored

How mail and documents are protected and kept: TLS enforced in transit, encryption at rest, end-to-end encryption or S/MIME and PGP, who at the provider can read a mailbox, two-factor authentication and passkeys, phishing, malware and account-takeover protection, audit-proof archiving that meets GoBD, retention policies and legal hold, eDiscovery, backups and restore of deleted mail, a transparency report on authority requests, and certifications (ISO 27001, BSI C5, SOC 2) with their scope.

0 — No security information of any kind; no encryption, two-factor sign-in or archiving stated.

3 — Encrypted connections and a password login; encryption at rest, two-factor sign-in, archiving and certifications are basic or not described.

5 — TLS in transit and encryption at rest stated, two-factor authentication, spam, phishing and malware protection, restore of deleted mail for a stated period, archiving offered (built in or as an add-on), and a certification such as ISO 27001 stated for the data centres or the service.

8 — End-to-end encryption, S/MIME or PGP supported, GoBD-compliant archiving documented, retention policies and legal hold, enforced two-factor or passkeys for all users, a transparency report on authority requests, and certifications such as ISO 27001 or BSI C5 published with their scope and auditor.

10 — Security that holds up in an audit of a regulated organisation: zero-access or customer-held keys where the provider cannot read mail, eDiscovery, tamper-proof archive with documented verification, every certification published with its report or attestation available, independent security audits or open-source code reviewed, and incident disclosure documented.

Report an error

The Small Firm Owner

Encryption at rest and in transit, one-click mail encryption with OpenPGP and ECC, two-factor with backup codes, anti-spam and anti-virus, 30-day mail restoration, ISO 27001 covering the information security management system, annual penetration tests, a bug bounty and a GDPR/FADP data processing agreement are all on the record, with a stated policy of no access to customer data without an explicit request. We found no public information on GoBD-compliant archiving, retention policies or legal hold — which matters to a Steuerkanzlei — nor on a transparency report on authority requests or admin-enforced two-factor. 3 6 7 10 17 18 19

Report an error

Administration, identity & partner management

How this is scored

How an IT team or an IT service provider runs it: an admin console for users, groups, mailboxes and domains, admin roles, single sign-on (SAML or OpenID Connect), sync with Active Directory, Entra ID or LDAP, SCIM provisioning, mobile device policies and remote wipe, audit logs of admin and user actions, usage reports, a documented API for provisioning, multi-tenant or reseller accounts for partners managing several customers, and the support channels and response times per plan.

0 — No administration; one login per mailbox and nothing managed centrally.

3 — A web console to add mailboxes and aliases; roles, single sign-on, directory sync and audit logs are basic or not described.

5 — An admin console for users, groups, mailboxes and domains, admin roles, two-factor sign-in enforceable by the admin, password policies, a documented API or command line for provisioning, an activity or audit log, and business support by phone or ticket stated per plan.

8 — Single sign-on (SAML or OpenID Connect), Active Directory, Entra ID or LDAP sync, SCIM provisioning, mobile device policies with remote wipe, audit logs exportable, delegated administration, partner or reseller accounts that manage several customer organisations, and support response times stated.

10 — Administration that scales across many organisations: every setting reachable by API with parity stated, granular role scopes, policies by group, logs streamed to a SIEM, white-label partner offerings with separate billing, and an SLA with service credits published.

Report an error

The Small Firm Owner

The manager offers roles from legal representative down to external users with limited rights, an activity log, unified account security review and a documented REST API with an OpenAPI file and OAuth 2.0; single sign-on via SAML 2.0 and automated provisioning via SCIM 2.0 work with Microsoft Entra ID and Okta on the Enterprise tier, and support answers by phone and ticket seven days a week. We found no public information on mobile device policies with remote wipe, exportable audit logs, stated response times, or partner and reseller accounts managing several customer organisations. 2 5 7 19 21

Migration, open standards & exit

How this is scored

How the organisation gets in and out: migration from Exchange, Microsoft 365, Google Workspace or another IMAP provider with a documented tool or service, mail, calendars and contacts carried over, coexistence during a move, standard protocols (IMAP, CalDAV, CardDAV, JMAP, open document formats) rather than proprietary ones, export of a mailbox and of the whole organisation in standard formats (mbox, EML, PST, ICS, vCard), open-source code or a self-hosted edition, what happens to data when the contract ends, and how domains and DNS are handed back.

0 — No way to bring mail in or take it out; a proprietary store with no IMAP access or export.

3 — IMAP access to mail; a migration path, calendar and contacts export and the end-of-contract handling are basic or not described.

5 — A documented migration from Exchange, Microsoft 365 or Google (a tool, an import or a service), mail, calendars and contacts imported, IMAP, CalDAV and CardDAV or ActiveSync access, export of mail, calendars and contacts in standard formats, and the deletion of data after the contract ends stated.

8 — A migration service or tool that moves whole organisations with calendars and permissions, coexistence with free/busy during the move, open document formats supported natively, export of the whole organisation by the admin, an open-source code base or a self-hosted edition, and a data return period after cancellation stated.

10 — An exit that costs nothing but time: every record exportable in open formats with the method documented, a self-hosted open-source edition with feature parity stated, migration in and out documented with the same tools, and a contractual data return and deletion with confirmation.

Report an error

The Small Firm Owner

A free expert migration moves domain names, websites and email addresses with the old service running until the transfer completes — the advice to cancel the old contract only after migration fits, old emails and folders transfer automatically, calendars and contacts move by ICS and vCard files, IMAP, CalDAV and CardDAV keep everything on standard protocols, and deletion of data including backups after termination is stated. We found no public information on a documented tool that moves a whole organisation from Microsoft 365 or Exchange together with permissions, on admin-side export of the entire organisation, or on a stated data-return period. 2 3 4 10 16 21 22

European sovereignty

How this is scored

Who the contracting entity and the parent company are, where mailboxes, calendars, contacts, documents and backups are stored and processed, who at the provider or its subprocessors can access them, and who the subprocessors are (data centres, spam filtering, support, payment, AI features). Independently sourced by the sovereignty pipeline. An EU data region offered by a non-EU parent is part of the chain, not the whole of it. A self-hosted or open-source edition the customer runs on its own European servers counts as the customer's chain, whatever the vendor's seat.

0 — Non-EU vendor and contracting entity, hosting unstated, subprocessors unnamed, and no data processing agreement offered.

3 — A privacy policy and a data processing agreement exist, but hosting location is unstated or non-EU and the subprocessors are not listed.

5 — EU hosting available and an EU contracting entity or EU representative, but parts of the chain (spam filtering, support, backups, AI features) run through non-EU providers or a non-EU parent without a stated safeguard.

8 — EU hosting on named infrastructure, EU contracting entity, subprocessors listed with their locations, a data processing agreement published, and security certifications (ISO 27001, BSI C5) stated — or a self-hosted edition documented that keeps every mailbox on the customer's own servers.

10 — Sovereign end to end and evidenced: European ownership, entity, hosting and every subprocessor, or a self-hosted open-source edition with no call home, data export and deletion documented, and certifications published with their scope rather than implied.

Report an error

The Small Firm Owner

Everything sits in the company's own Swiss data centres with a stated policy of never transferring data outside its own infrastructure, the firm is employee-controlled with a foundation protecting its independence, the legal framework is described as GDPR and Swiss FADP with protection from the Cloud Act, an ISO 27001 certificate and a published data processing agreement are on record, and subcontractors for payments, two-factor SMS and website forms are named. The contracting entity and hosting are Swiss rather than EU, however, and the named subcontractors appear without their locations. 6 8 9 10 12 17 18

Pricing transparency

How this is scored

Whether a buyer can compute the real annual cost from public pages alone: price per user or mailbox per tier, storage per user, what shared mailboxes, aliases and extra domains cost, which features (archiving, office apps, SSO, advanced security, more storage) cost extra, the first-year discount and the regular price after it, minimum users and term, monthly versus annual billing, and VAT.

0 — No public prices at all; every customer is a sales call.

3 — A starting price per user exists, but how cost scales with storage, users, add-ons or after the first year is unclear.

5 — Tiers are public with their price per user and main inclusions, but at least one commonly needed piece (archiving, extra storage, shared mailboxes, SSO, the price after the introductory period) is unpriced or "on request".

8 — Every tier priced publicly per user with storage, add-ons priced, the regular price after any introductory discount stated, minimum users and term stated, monthly and annual billing compared, and VAT treatment stated.

10 — Complete price computability: annual cost derivable for a given number of users, storage and add-ons, with every support, migration and archive fee and the cancellation and data-return terms published.

Report an error

The Small Firm Owner

Every tier is priced per user in Swiss francs with storage, address counts, room counts, version history and send limits attached, the regular price after the first-year discount is printed plainly — "Business -50% im ersten Jahr CHF 7.34 3.67 pro Benutzer / Monat" — an optional kDrive starts at CHF 5.35 / Monat, and prices are stated exclusive of VAT. We found no public information on minimum users or term, a monthly-billing option, or the price of Premium Support, and the captured pages give different figures for what a CHF 1.76 per-user plan includes. 1 2 3 7 9
