Microsoft Exchange email by IONOS by 1&1: here’s how it works

Professional communication solutions

Microsoft Exchange is a popular email and groupware server solution used by companies of all sizes around the world. The software includes powerful collaboration features that help organisations to optimise both internal and external collaboration and communication processes.

Microsoft Outlook is also available as client-side software, meaning employees always have full control over emails, appointments and contacts. With Exchange-based Outlook, colleagues can easily see whether you are in a meeting or on holiday – making light work of joint scheduling and project work.

FAQ – Frequently asked questions

In the past, email solutions were often configured and managed in-house, but at the cost of time, money and personnel. Nowadays, however, many companies have switched to external services such as Hosted Email Exchange with IONOS. There are many reasons for outsourcing:

  • You stay flexible by scaling your Exchange resources when needed.
  • You save on the expensive maintenance of an in-house email server.
  • Your IT department has more time to concentrate on projects of higher importance.
  • You save on the cost of licensing.
  • You receive both the server infrastructure and, thanks to Microsoft Outlook, the software solution for working on the go.

Yes – that will be possible in the future. We are currently working hard to provide our customers with the simplest possible migration functionality. However, when exactly this function will be available is yet to be determined. Check back with us for further updates.

If you are already a IONOS customer, you can contact your personal consultant at any time to receive comprehensive advice on migration and upgrade methods.

Although the Hosted Exchange from IONOS is primarily aimed at companies, there are also good reasons for private users to choose a professional and reputable email solution:

  • You benefit from an email solution free from advertising.
  • With the Microsoft Outlook solution, you get a proven, clear and secure software product for emails and scheduling.
  • Thanks to the comprehensive spam filter, you are better protected against undesired emails or dangerous phishing.
  • You will gain full access to all Outlook features that also make personal life easier: for example, when you're on holiday, you can set up an out of office message or set reminders for important events in your calendar.
  • Thanks to countless apps and a separate browser version, you can synchronise your mailboxes and calendars across all your devices in an instant.

There are many good reasons for using Hosted Exchange by IONOS, both for private users and for companies. While the benefits of a mobile, flexible and scalable email solution for businesses are obvious, private use cases may initially seem less obvious. However, there are plenty of scenarios, such as:

  • Study: Private and university emails can be easily sorted and managed with Outlook. This makes it easier for you to keep track.
  • Looking for a job: Applying for a job is done almost exclusively online. A professional email solution makes it easier for you to keep track, and the individual mail domain included makes a more credible impression on potential employers. You can also read our Digital Guide article with tips on writing business emails that leave a lasting impression.
  • Daily family life: Thanks to a synchronised calendar, couples and families can record clearly arranged appointments from any end device – be it children's school events, doctor's appointments or simply the weekly shopping list and the chores for the week.
  • Flat rentals: Flat owners often receive numerous emails from their tenants. Hosted Exchange, which includes Outlook, operates as an efficient software solution that simplifies the general overview – meetings with the owners, flat viewings or flat inspections can easily be organised digitally and without paperwork.

There's plenty more application examples to add to the above list. If you are looking for an alternative emailing solution, you're guaranteed to find a suitable product with IONOS. Do you still require Outlook tools for team collaboration? With our simpler plans, you also have the option of receiving your own email address. Or you can opt directly for the complete Microsoft 365 package, which is also available from IONOS – both come with expert-level support.
