Warning about Outlook apps

These apps send login data (login name and password) to Microsoft, which in particular violates the TU-ID terms of use. The new Outlook app ensures that all emails are sent to Microsoft for analysis. Therefore, the use of the Outlook app for mobile devices (Android and iOS) and the new Outlook app for Windows is prohibited for information security and data protection reasons.

However, the classic licence-based Outlook programme can still be used. This is part of the Microsoft Office package and retrieves emails directly from our servers without storing the login data in the Microsoft Cloud. You can use Outlook under Windows and MacOS in the current versions (2016, 2019 and 2021 as well as M365).

Using the web-based version, the Outlook Web App (OWA), is also not critical.

Classic Outlook is also currently being revised by Microsoft. If there are any restrictions on the use of future versions of the Outlook included with Office, we will inform you.
