Microsoft Exchange hosting — FAQs

Why should I not run my email environment in-house?

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 or exiting the data center:

  • 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.

If I opt for Hosted Exchange, can I upgrade to Microsoft 365 any time?

Yes, that will be possible in the future. We are currently working on providing our customers with the simplest possible migration functionality. However, the exact date of when 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.

Is the product only suitable for small businesses?

No, 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 home and personal use. Here's why:

  • 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.

Can you be more specific about non-commercial uses for Hosted Exchange?

Yes! While the benefits of a mobile, flexible and scalable email solution for businesses are obvious, non-commercial use cases may initially seem less obvious. However, here are a couple of common scenarios:

  • Microsoft Exchange for education: University email can be easily sorted and managed with Outlook. This makes it easier for you to keep track of your correspondence. Due to Outlook's familiarity with educators, MS Exchange is also a great solution for schools and administrators too.
  • MS Exchange for personal use: Applying for a job is done almost exclusively online. A professional email solution makes it easier for you to keep track, and an individual email domain makes a more credible impression on potential employers. You can also read our Digital Guide article with tips on writing business email that leaves a lasting impression.
  • Microsoft Exchange for home use: Thanks to a synchronized calendar, families can record and share appointments or to-do lists from any device. 
  • Exchange for non-profits: Hosted Exchange is also a great product for non-profits, charities, places of worship or other institutions. Exchange is fully scalable — you can add more users at any time — so as your organization grows, Exchange grows with you.

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.

Which backup features does Microsoft Hosted Exchange offer?

With the Microsoft Hosted Exchange by IONOS, you can rely on extremely high security and backup standards and all data is stored georedundantly. This means:

  • All data is stored in two independent data centers.
  • Your data is always available as exact copies and is replicated from the primary data center to the secondary data center in another location.
  • Our emergency power generators, state-of-the-art fire control and strict security ensure maximum protection against failure in every data center we operate.
  • Even in the event of natural disasters on site, georedundant storage ensures that you do not lose any data.

What is Microsoft Exchange?

Technically speaking, Microsoft Exchange is a groupware server that powers email hosting and Microsoft's most popular productivity tool, scheduling assistant and email client, Outlook. Outlook is connected to Exchange, which works as a server application that is hosted on physical servers like those that reside in IONOS's proprietary data centers in the US and Europe.
