Hosted Microsoft Exchange by 1&1 IONOS: Here’s how it works

Professional communication solutions for a strong company:

Microsoft Exchange is a popular email and groupware solution among companies of all sizes worldwide. The software includes powerful collaboration features that help organizations to optimize both internal and external collaboration and communication processes. Microsoft Outlook is also available as client-side software: employees always have full control over emails, appointments and contacts. With Exchange, colleagues can easily see whether you are in a meeting or on vacation – this makes light work of joint scheduling and group work.

  • Thanks to our geo-redundant infrastructure, your company’s important data is optimally protected against failure and loss.
  • Your data is stored in accordance with US data protection regulations

Combine maximum productivity with maximum availability:

How does the Hosted Exchange email solution work and what do customers need to know?

Administration of MS Exchange server

There is no need to worry about the administration of the email Exchange server, because we provide a “managed” Exchange server: while you and your colleagues take care of driving your business forward, we take care of server maintenance and security for you. You can also benefit from the latest security technology: you will get all important security updates and your data is protected against loss or malfunction.
The connection to the server is simple for you and your employees via Microsoft Outlook. This allows you to access your mails, contacts and appointments from all your devices via apps and the browser anytime, anywhere.

Connecting email accounts to Exchange

You can easily connect both existing and new email accounts with the Hosted Exchange email server in just a few clicks. Since the 1&1 Exchange solution is a flexible and easily scalable product, you can add more email accounts and mailboxes at any time. As your business grows, your hosted Microsoft Exchange environment grows with you!
All you need to do is purchase another license and add it to your existing account. This way, you can ensure in the long run that every new employee receives their own email address and an individual domain.

You can rely on top-class service

The Exchange technology is developed by Microsoft and is used worldwide – including in the 1&1 IONOS data centres, which are operated and professionally maintained exclusively by us.
You benefit not only from the world’s most important groupware solution from Microsoft, but also from our leading server technology and the highest standards. All of our high-security data centres guarantee maximum reliability thanks to geo-redundant mirroring of all data at independent locations. And should you have any questions about the server or any difficulties, you can reach us around the clock!

Microsoft Exchange Hosting

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 Exchange with 1&1 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 have more time to concentrate on projects of higher importance.
  • You save the cost of tedious licensing.
  • You receive both the server infrastructure and, thanks to Microsoft Outlook, the software solution for mobile work.
Yes – that will be possible in the future. We are currently working hard to provide our customers with the simplest possible migration functionality. When exactly this function will be available, however, is currently undecided.

If you are already a 1&1 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 1&1 IONOS is primarily aimed at companies, there are good reasons to rely on a professional and reputable email solution for private use also:

  • You benefit from an advertising-free email solution.
  • With the Microsoft Outlook solution, you get a proven, clear and secure software 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 private life easier: for example, when you're on holiday you can set up an out of office message or personal reminders for important meetings and tasks in your calendar.
  • Thanks to countless mobile apps and a separate browser version, you can synchronize your mailboxes and calendars across all your devices in an instant.
There are many good reasons for using Hosted Exchange by 1&1 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 mails can be easily sorted and managed with Outlook. This makes it easier for you to keep track.
  • Job Seeking: Today, applications are mainly submitted online. A professional email solution makes it easier for you to keep track, and the individual mail domain it contains makes a serious impression on potential employers. You can also read our Digital Guide article with tips on writing business mail that leaves a lasting
  • Daily family life: Thanks to a synchronized calendar, couples can record clearly arranged appointments from any end device – be it children's school events, doctor's appointments or simply the shopping and cleaning plan for the week.
  • Private apartment rentals: Apartment 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, apartment viewings or apartment inspections can easily be organized digitally and without paperwork.

There's plenty more application examples to add to the above list. If you are looking for an alternative mail solution, you're guaranteed to find a suitable product with 1&1 IONOS. Do you still require Outlook tools for team collaboration? With our simpler tariffs, you also have the option of receiving your own email address. Or you can opt directly for the complete Microsoft Office 365 package, which is also available from 1&1 IONOS – of course both with our proven expert support.
