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

Professional communication solutions for a cohesive company

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 organizations to optimize 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 vacation — making light work of joint scheduling and project work.

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 also benefit from the latest security technology — all important security updates are taken care of for you and your data is protected against loss or malfunction.
Your connection to the server is simple via Microsoft Outlook. This allows you to access your emails, 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 IONOS 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 IONOS data centers, 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 centers 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!

And of course, as always, IONOS is there to help you with the configuration. Simply contact your personal consultant — a free service available only to IONOS customers. You can learn more about this service here.

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 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 the cost of tedious licensing.
  • You receive both the server infrastructure and, thanks to Microsoft Outlook, the software solution for remote working.
Yes — that will be possible in the future. We are currently working on providing our customers with the simplest possible migration functionality. However, when exactly this function will be available has 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 good reasons to rely on a professional and reputable email solution for private use also:

  • You benefit from an email solution free from advertising.
  • With the Microsoft Outlook solution, you get a proven, clear and secure software product designed for emails and scheduling.
  • Thanks to the comprehensive spam filter, you are better protected against undesirable emails and dangerous phishing.
  • You gain full access to all Outlook features that also make your personal life easier: for example, when you're on vacation 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 synchronize 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 email can be easily sorted and managed with Outlook. This makes it easier for you to keep track of your correspondence.
  • 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 it contains makes a more credible impression on potential employers. You can also read our Digital Guide article with tips on writing a business email that leaves a lasting impression.
  • 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 list and your chores for the week.
  • 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 picture — 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 emailing solution, you're guaranteed to find a suitable product from IONOS. Do you still require Outlook tools for team collaboration? With our simpler plans, you also have the option of getting your own email address. Or you can opt directly for the complete Microsoft Office 365 package, which is also available from IONOS — both come with expert-level support.
