Microsoft 365 — FAQs

This is a very simple transition: Office 365 business plans will now become Microsoft 365 business plans. This means it’s a new name, but still the same great plan at the same price. In terms of the IONOS package changes, please keep in mind the following:

  • OfficeBusiness will now be called Microsoft 365 Business Basic
  • OfficePremium Plus will now be called Microsoft 365 Business Standard

These name changes are to display the excellent range of features and benefits in this subscription model more clearly. Microsoft 365 still has everything great about Office 365, including the useful products, cloud service, and cutting-edge security, but the name change will assist customers to find the perfect plan for the right situation. This means a business enterprise, a small to medium-sized business, or an individual, can all find the right plan faster and easier.

Despite the fact that the business plan names have changed, IONOS will keep the products and prices the same. The same deals will simply be available under a new name. If your business already has an existing Office 365 Business subscription, then the name change to Microsoft 365 still means no action is needed from you. Your Office 365 subscription will simply now be called Microsoft 365. You will be able to see the updated name via your admin portal and monthly billing reports. Microsoft 365 will continue to be a powerful cloud-based subscription model for Microsoft Office products such as Word, Excel, PowerPoint, Outlook, and much more. This subscription means that you’ll always have the latest Microsoft product version whenever it’s released and there’s no need re-purchase any update. Microsoft 365 is designed so that documents can be accessed from any device no matter where you are. This helps you to finish work efficiently and return to what matters most in your life. Microsoft 365 comes with the best office apps, modern cloud functionality, and top-of-the-line security.

An Microsof 365 subscription includes the complete current range of Microsoft Office products, including individual applications such as Word, Excel, PowerPoint, Outlook and more. The latest version is Office 2021. Rather than having to constantly buy the latest version of Office, the subscription only needs to be purchased once. You then pay a monthly fee for Microsoft 365 and benefit from complete flexibility, with the latest versions of all applications at your disposal. Continuous updates also protect you from any security risks that leave you vulnerable to viruses and malware. Additionally, the Microsoft 365 subscription allows you to access your documents, tables, emails and files from web browsers or mobile apps, affording you maximum mobility. This brings your office to you, wherever you are. How you use Office 2021, and from which device, is entirely up to you.

Microsoft 365 is a monthly subscription service, meaning you pay a small fee every month rather than one large initial payment, as the traditional Microsoft Office requires. As you also no longer have to purchase newer versions of Office thanks to the updates, the subscription service actually saves you money. Administrative tasks and time spent on installing and setting up new software versions are also greatly minimized. Furthermore, maintenance effort is reduced as the Microsoft 365 subscription guarantees you will automatically receive the newest software available in just a few clicks. This payment structure is particularly beneficial if you always want to be up to date and need an easy, yet comprehensive solution. This makes Microsoft 365 suitable for companies and private users who need a professional office solution. Beginners also profit from an Microsoft 365 package with IONOS: they receive a more affordable Office 365 package, while enjoying the same high standard of service from our 24/7 expert hotline.

You receive both with IONOS: a useful online version and the Office 2021 offline installer for your devices. This means you can access your documents, spreadsheets and emails via a web browser from anywhere, and also install an offline version of the software. With just one subscription, you can install Microsoft 365 on up to five devices of your choice. If you are working from a device that doesn't belong to you without an installed version of Microsoft 365, simply use the web browser to access the online version. This means you can be flexible and productive, no matter where you are or whether you are connected to the internet or not. What's more, our packages also include the Office mobile apps, so you can install your Office 2021 on your Android or iOS device. The apps enable you to continue to work using up to five mobile devices, even without a working internet connection — perfect for while traveling through regions without network connection on the train or when in airplane mode.

IONOS offers an appropriate Microsoft 365 plan for all users regardless of skill level or budget.

Our entry-level plan includes a suite of Office applications such as Word, Excel and PowerPoint, with fully functional online and mobile app versions. This plan also includes a professional email solution with a large inbox capacity based on Exchange technology, as well as OneDrive for Business cloud storage solution, featuring extensive online storage space that helps you store and access your files from anywhere. Finally, Microsoft Teams keeps you connected to your partners or colleagues. What is not included in this package is the possibility to locally install your favorite Office applications on desktops or laptops.

Our high-end plan is an all-inclusive productivity solution. It includes everything that mentioned in the previous package. Office applications that can be installed locally on up to 5 devices per user or used online through a browser or with mobile apps, a professional email solution based on Exchange technology as well as OneDrive for Business cloud storage and Microsoft Teams. You can make use of an individual domain (needs to be purchased separately), so that you can convey professionalism when sending emails. The email software included in this plan, Outlook 2021, allows you to easily manage all your emails, appointments and tasks.

Ultimately, the choice is yours, as our plans are ideal for a wide range of uses. All our Microsoft 365 plans meet the requirements of a business, but are also suited for private users and freelancers. If you still have questions about our Microsoft Office 365 offer, simply give us a call. Our experts are happy to help you choose the right plan.
