You receive both with IONOS: a useful online version and 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. 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 Microsoft 365 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 using while travelling through regions without network connection on the train or when in airplane mode.
