Getting started

Overview

This article describes how to start INGOS Mail: opening the app, linking your own mailbox if that has not happened yet, and the buttons on the right of the header bar.

Requirement: an INGOS account on my.ingos.com with access to the Email app.

Opening the app

  1. Sign in to my.ingos.com.
  2. Open the E-Mail (Email) app.
  3. While loading, Postfach wird geladen … (Loading mailbox …) appears. Then the Inbox of your own mailbox opens.

On the INGOS desktop, the app runs in its own window; the window title shows its name. If the app runs on its own in a browser tab, INGOS E-Mail with the app icon also appears at the top of the navigation.

The app always opens in the E-Mail (Email) area. It does not remember which area was last open across a reload. Within a session, switching back to E-Mail takes you to the folder you last opened.

If no mailbox is linked yet

If no mailbox is linked to your account yet, the card Kein Postfach verknüpft (No mailbox linked) appears instead of the list and reading pane. The navigation then shows only Posteingang (Inbox) and Einstellungen (Settings); Neue E-Mail (New email) is missing. The Calendar, Contacts, Notes and Tasks areas also show this card, because all areas belong to the mailbox.

The text below it depends on whether you may link your own mailbox yourself:

  • Eigenes Postfach unten verknüpfen. Danach erscheint es hier. (Link your own mailbox below. It will then appear here.) Below it is the card Eigenes Postfach verknüpfen (Link your own mailbox) (steps below).
  • Die Zugangsdaten des Postfachs hinterlegt die Administration in der Administrations-App. Danach erscheint es hier. (The administration stores the mailbox credentials in the administration app. It will then appear here.) In this case, your company's administration links the mailbox. As soon as that is done, choose Aktualisieren (Refresh) or reload the page.

“Kein Postfach verknüpft” (No mailbox linked) card with the “Eigenes Postfach verknüpfen” (Link own mailbox) form

Linking your own mailbox

Linking is done on the Kein Postfach verknüpft (No mailbox linked) screen in the Email area, separately under Einstellungen (Settings) › Postfach (Mailbox).

  1. Under Postfach-Adresse (Mailbox address), check the address of your own mailbox. It is prefilled with the address you used to sign in to my.ingos.com.
  2. Under Passwort des Postfachs (Mailbox password), enter the mailbox password.
  3. Choose Verknüpfen (Link). During the check, Anmeldung am Mailserver wird geprüft … (Checking sign-in to the mail server …) appears.
  4. After a successful check, the app reloads and shows the Inbox.

Fields:

  • Postfach-Adresse (Mailbox address): email address of your own mailbox. It must be in the same domain as your sign-in address, and that domain must belong to your company.
  • Passwort des Postfachs (Mailbox password): checked once against the mail server, stored encrypted and never shown again.

Possible messages:

  • Bitte Adresse und Passwort angeben. (Please enter address and password.) A field is empty.
  • Bitte eine gültige E-Mail-Adresse angeben. (Please enter a valid email address.) The address does not have a valid format.
  • Bitte das Passwort des Postfachs angeben. (Please enter the mailbox password.) The password is missing.
  • Postfach-Zugangsdaten ungültig. (Mailbox credentials invalid.) The address or password is wrong.
  • Das eigene Postfach muss unter der Domäne der eigenen Anmeldeadresse liegen. (Your own mailbox must be in the domain of your sign-in address.) An address from a different domain was entered.
  • Die Domäne der eigenen Anmeldeadresse gehört nicht zu diesem Mandanten. (The domain of your sign-in address does not belong to this tenant.) The domain of the sign-in is not assigned to your company at INGOS; your administration or INGOS can clarify this.
  • Die Anmeldung gehört zu einer anderen Adresse als angegeben. (The sign-in belongs to a different address than the one entered.) The password belongs to a different mailbox.

Note

After five failed attempts within ten minutes, linking is briefly locked. After waiting a few minutes, you can try again.

Only your own mailbox can be linked this way. The administration links other people's mailboxes. An existing link is shown, and can be removed, in Settings under Postfach (Mailbox).

Buttons on the right of the header bar

Buttons for new email sound, dark mode, and refresh

From left to right:

  • Ton bei neuer E-Mail (Sound for new email): turns a short alert sound for new mail on or off. Default: off.
  • Dunkler Modus (Dark mode) or Heller Modus (Light mode): switches the appearance. Default: dark.
  • Aktualisieren (Refresh): reloads the mailbox, folders, categories and storage indicator.

Light or dark

  1. In the light design, choose the button with the moon (Dunkler Modus (Dark mode)); in the dark design, choose the button with the sun (Heller Modus (Light mode)).
  2. The app switches immediately, without a menu and without reloading.

The choice is saved in this browser and applies there to all INGOS apps.

INGOS Mail in the dark theme

In the dark design, messages also appear dark with light text. You can turn this off in Settings › Anzeige (Display), or change it per message using the sun in the reading pane.

Sound for new email

  1. Choose Ton bei neuer E-Mail (Sound for new email). The icon changes from a crossed-out to an active speaker, and the sound plays once as a test.
  2. Choose it again to turn the sound off.

The setting applies to this browser and all its tabs. When the sound plays is described in New messages and notifications.

Refresh

Aktualisieren (Refresh) rebuilds the app with fresh data without reloading the page. An open message is closed in the process. For the open folder alone, Aktualisieren in the header of the message list is enough. New messages appear automatically anyway.

The "Neue Fassung verfügbar" notice (New version available)

If a new version of the shared foundation of the INGOS apps is released while you are working, the notice Neue Fassung verfügbar (New version available) appears at the bottom. Neu laden (Reload) loads the app in the new version; the X (Hinweis schließen (Close notice)) hides it. The app checks for this when you return to the tab and every 15 minutes. Reloading the page always fetches the latest version.

WARNING

Before "Neu laden" (Reload), save open drafts with "Entwurf speichern" (Save draft). A draft is not saved automatically.
