Note on unauthorized e-mail apps

A number of apps and programs are not permitted to retrieve emails from the University Münster mailboxes (both via Exchange and IMAP or POP).
The list currently includes the following applications:

  • Outlook-App for Android and iOS
  • Outlook for MacOS (when using IMAP with CloudSync)
  • The "new Outlook" or "Outlook (new)" (the Outlook version pre-installed under Windows 11)
  • Edison Mail
  • Newton Mail
  • Spark Mail
  • BlueMail
  • Xiaomi Mail/MiMail
  • Canary Mail
  • myMail
  • Mail.ru
The reason for this is that these programs and apps transmit content data and, in particular, passwords to third parties via cloud synchronization. If you are currently using one of these applications, uninstall it and then change your password in the IT portal. If you have already used such an application in the past and have not yet changed your password, please do so immediately.

Further information on transferring data to a cloud via e-mail applications can be found here.

This note supplements the existing warnings about the Microsoft Outlook app for Android and iOS, and the Edison Mail app, Outlook for MacOS and the “new Outlook” .
