Integrated Kerio Connect groupware

Everything in one solution

Email, calendars, contacts and tasks combined in Kerio Connect, securely hosted by walkingtoweb.

We have more than 25 years of experience in hosting groupware, with personal support and smooth migration. Additional services such as a mail gateway further increase the security of your email.

One contact – one platform – full digital sovereignty

What is email groupware?

An email groupware combines everything teams need day to day – email, calendars, contacts, tasks and notes – in one seamless solution. Instead of maintaining several programs, everyone accesses the same shared data. Changes to appointments, addresses or tasks are immediately synchronised across all devices and users.

The real added value lies in sharing: shared calendars for easy planning, shared contacts for the whole company and public folders in which knowledge is stored centrally. A good groupware synchronises reliably between server, browser and mobile device so that your team is always working with the latest information.

Kerio groupware turns individual mailboxes into a central hub for corporate communication.

Kerio Connect is the modern, central email platform for everyday collaboration.

What makes Kerio Connect better?

Kerio Connect excels where large platforms often become too complex: with clarity, stability and fair value for money. The solution runs lean and reliably without time-consuming administration – ideal for small and medium-sized businesses that want modern business email groupware without the complexity and error-proneness of Microsoft Exchange.

Kerio Connect is cross-platform and therefore compatible with macOS, Windows and Linux as well as with common mail clients such as Apple Mail, Outlook or Thunderbird. Thanks to ActiveSync, smartphones and tablets are connected directly, so your emails, appointments and contacts stay up to date everywhere.

The result: a powerful yet easy-to-maintain solution that makes everyday work noticeably easier.

As a secure, high-performance alternative to Exchange and other email servers, Kerio Connect has been the best email groupware solution for businesses for many years.

Why should we use Kerio Connect?

Where your emails are stored determines who is allowed to see them. With hosting in Switzerland, your data remains in a country with one of the strictest data protection laws in the world – out of reach of foreign authorities (e.g. under the CLOUD Act). This is particularly relevant for businesses, law firms, fiduciaries and medical practices that work with confidential information.

Kerio Connect hosted in Switzerland combines this legal certainty with personal support: you know where your data is, you know your contact person and you receive support in your language and time zone. Kerio Connect hosting by walkingtoweb is FADP and GDPR compliant, for demonstrable compliance towards customers and partners.

With a Kerio Connect server from walkingtoweb, you use a secure, data-protection-compliant email service for your daily communication.

What can the mail server do?

Kerio Connect is far more than a mail server. It combines email, calendars, contacts, tasks, notes and shared folders in one integrated environment, synchronised centrally across all devices.

Kerio Connect groupware uses open standards (IMAP, SMTP, POP3, CalDAV, CardDAV) and synchronises mobile devices via ActiveSync. This lets you connect Apple Mail, Outlook, Thunderbird or native apps on iOS and Android without any problems. Alternatively, Kerio Webmail is available in the browser, with no installation required.

Security is ensured by TLS encryption, spam and virus protection, filters, archiving, automatic backups and central, intuitive administration.

Kerio Connect is a mature and dependable email groupware that serves as a complete communication centre for email, calendars and tasks.

Why is digital sovereignty so important?

Email is the memory of a business – contracts, quotations, internal arrangements and customer data flow through it every day. Anyone who gives up control over this communication loses a piece of entrepreneurial freedom. Digital sovereignty means that you decide where your data is stored, who may access it and under which rules it is processed.

Many international providers store data outside Europe, under foreign laws and with potential use for algorithms or advertising. This makes it impossible for you to meet your compliance obligations and applicable laws.

Sovereignty means: open standards instead of dependency, clear locations instead of a black box, data protection instead of data exploitation. Especially with email, this independence is not a luxury but a prerequisite for trust and responsibility towards your customers.

Independence starts with your email.

Why is walkingtoweb the best choice?

Experience, personal support and reliability since 2001 are what set us apart.

FAQ
Frequently asked questions

For further questions and clarification about the functions and possibilities of email groupware hosting with Kerio Connect, please feel free to contact us.

You will find a wide range of further resources on Kerio Connect directly from the developer.

  • What is the difference between groupware and a normal email service?

    Groupware describes a system for collaboration within a team. Groupware therefore covers not only email but also other services that are important for effective collaboration: calendars, tasks, resources (such as rooms, vehicles or equipment), notes, contacts, groups and chat.

    In many companies, information is not edited and used jointly but forwarded. This wastes resources and therefore time and revenue. In a groupware, all areas can be shared with other users or groups with different access rights and edited together. Groupware lets you optimise your workflows.

  • Where are the emails stored?

    walkingtoweb operates exclusively its own infrastructure in a high-security Swiss data centre. All data is stored solely and exclusively in Switzerland. No work is outsourced – we also rely on our own staff for customer support.

    walkingtoweb complies with all Swiss data protection regulations and therefore also with all data protection regulations applicable in the EU / DE / AT, including the GDPR. We have repeatedly passed several compliance audits by customers in the financial, medical and public administration sectors.

    We hold the Swiss Hosting label, which verifies the highest standards of data security.

  • Can I use 2FA?

    Yes, two-factor authentication (2FA) greatly increases the security of your email. We generally recommend enabling this security feature.

    For configuration, you need a 2FA app on your mobile phone to generate a real-time token.

  • Can mailboxes and calendars be shared?

    Yes. You can use the email cloud in webmail or integrate it into your local email apps via IMAP. Each mailbox can be used jointly from any number of devices.
    Via webmail, you can also share individual folders or subfolders with other email accounts. This allows several people to read and reply to emails. Thanks to the IMAP protocol, sent emails are also synchronised to all devices.

  • How many email addresses can I use?

    The basis of the email groupware is the mailbox. A mailbox is, for example, a person for whom a mailbox is created. You can assign any number of email addresses to each mailbox. If you have assigned several domains as alias domains, this account can receive emails for all of these domains.

    In addition to mailboxes, there are groups. Emails to a group are forwarded to the defined mailboxes. A group does not use up a mailbox, and you can create as many groups as you like.

    If a mailbox is deleted, e.g. when an employee leaves the company, you can create aliases. An alias is a forwarding address and can be used, for example, for deactivated email accounts to forward emails to another mailbox. You can create as many aliases as you like.

  • Can I use IMAP and POP3 in parallel?

    Yes, you can access a mailbox with all connection types (IMAP, POP, webmail) at the same time.
    To be able to use the same data on all devices, we recommend IMAP.

  • Are backups of the email servers created?

    Yes, we back up all virtual servers to two separate backup systems. We apply the following backup rules:

    • Backup of all servers: 14 days, 1 x per day
    • Backup of all servers: 4 weeks, 1 x per week
    • Backup of all servers: 3 months, 1 x per month

    If you need a restore, please contact our support team.

  • Can I transfer an on-premises Kerio Connect server to walkingtoweb?

    Yes, we can take over existing email servers based on Kerio Connect 1:1, including licences and directories. The migration can be carried out either as a copy or as an import; please contact our sales team for a detailed assessment.

  • Can I set up an out-of-office message?

    In webmail, open the Out of Office menu at the top right and enter a message there, which is sent once to each sender during the defined period.

  • Is delegation possible, e.g. for scheduling?

    In the Settings / Delegation menu, you can define colleagues who may edit your calendar on your behalf (important for invitations) or reply to emails in your inbox on your behalf. You can grant these rights either for the entire account or only for individual folders / calendars.

  • What limitations are there?

    With Email Cloud Shared, emails including attachments of up to 100 MB are possible.
    For private email cloud servers, we recommend an email size limit of 200 MB.

    The number of stored emails (and events) is limited only by the storage size. Storage is specified per mailbox and you can distribute it freely between all mailboxes yourself.

    Up to 500 emails per hour can be sent from one IP address.
    For business customers with several workstations, a higher limit can be set on request.

    To optimise the performance of the email server and the clients, a folder should not contain more than 10,000 emails. Please note that the Inbox and Sent Items folders are constantly synchronised and indexed. These folders should therefore not exceed the recommended number of emails.

  • Does walkingtoweb manage the DMARC, DKIM and SPF records?

    For all domains managed by walkingtoweb, we also take care of managing the DMARC, DKIM and SPF records for you. If DNS management is not handled by walkingtoweb, you will need to make these changes with your DNS registrar. We also offer management of your email security as an option – you can find more information here.
