Warning About Free Outlook Apps

Attention! Microsoft has released new free apps for Outlook. However, the new Outlook apps store your login data (login name and password) in the Microsoft cloud. Emails are also transmitted to Microsoft without your consent.
Therefore, business use is prohibited for information security and data protection reasons. We also strongly advise against private use.
License-based Outlook programs, for example from Microsoft Office, and the Outlook Web App (OWA), which can be opened via a browser, are not affected. These may continue to be used. There are currently no security concerns, as these applications communicate directly with the RWTH Aachen University mail servers and no data is transferred to the Microsoft cloud.
We have put together a short FAQ for you on what you should know about this.
