Error messages and limits

Overview

This article lists the messages INGOS Mail can show, with the likely cause and the next step. The fixed limits of the app are listed at the end.

Messages usually appear as a notice at the top right (title and text) or as a box Etwas ist schiefgelaufen (Something went wrong) with the Erneut versuchen (Try again) button. If none of the steps helps, contact INGOS support with the exact wording of the message and the time.
