Important! Unwanted cloud storage in free "New Outlook" apps

The new free Outlook app for Windows 10 and 11 and the Outlook apps on mobile devices (Android and iOS/macOS) must not be used for information security and data protection reasons, as they transfer unwanted data to Microsoft.

License-based Outlook programs (from Microsoft Office) and the "Outlook on the Web" app (OWA) are not affected and can be used. There are currently no security concerns here, as these applications communicate directly with the RWTH Aachen University mail servers and no data is transferred to the Microsoft cloud.

What is the concern about the free Outlook apps?

The currently available free Outlook apps for Windows 10 and 11 as well as the Outlook apps on mobile devices (Android and iOS/macOS) synchronize access data and emails with the Microsoft cloud.

Users are not informed that their passwords are also stored in the cloud. Outlook apps for Android, iOS and macOS function similarily.

Use of free Outlook apps for business purposes is not permitted!

The use of the Outlook app for mobile devices (Android and iOS/macOS) and the new Outlook app for Windows is prohibited for information security and data protection reasons. We also strongly advise against the private use of the free Outlook apps.

Which Outlook versions can I use?

Instead, we recommend using the license-based Outlook versions (2016, 2019, Office 365) and the Outlook Web App (OWA)..
