Mailboxes and sharing

Overview

In addition to your own mailbox, INGOS Mail also shows folders that other people have shared with your mailbox. This article explains the mailbox selector in the header bar, the Mit mir geteilt (Shared with me) node in the navigation, and who may see and do what.

Requirement: your own mailbox is linked, see Getting started. Shares are set up by the person who owns the mailbox; shares cannot be created in INGOS Mail itself.

Mailbox selector in the header bar

The mailbox selector with an envelope icon and an arrow sits at the top left of the header bar. It shows the address of the currently selected mailbox (without an address, "Eigenes Postfach" (Own mailbox)) and is visible as soon as a mailbox is linked. Its menu offers your own mailbox and every person who shares folders with it, with the number of unread messages.

  1. Click the mailbox selector.
  2. In the menu, choose the mailbox you want:
    • First entry: your own mailbox with its address.
    • Below it: one entry with a person icon and address for each person who shares folders with your mailbox, sorted alphabetically. On the right is the number of unread messages in that person's shared folders.
  3. The navigation then shows the folders of the selected mailbox and opens its Posteingang (Inbox).

The choice is saved in the browser. If a person no longer shares any folders, the selection jumps back to your own mailbox the next time the app loads.

View of a shared mailbox

When another person's mailbox is selected, the navigation shows only the folders that person has shared, without the Mit mir geteilt (Shared with me) node. In the example, Dirk Vater has shared only his Posteingang (Inbox).

  • The person's standard folders appear with their German name and matching icon (Posteingang (Inbox), Gesendet (Sent) and so on).
  • In INGOS Mail, categories can be managed only for your own mailbox, see Categories.
  • In shared Gesendet (Sent), Entwürfe (Drafts) and Geplant (Scheduled) folders, the list shows the recipients instead of the sender, as in your own mailbox.

The storage indicator always applies to your own mailbox, even if another person's mailbox is selected at the top.

Back to your own mailbox: open the mailbox selector and choose the first entry.

The "Mit mir geteilt" node (Shared with me) in your own mailbox

In your own mailbox, the Mit mir geteilt (Shared with me) node appears below your own folders. It lets you open shared folders without switching the mailbox selector. Under Mit mir geteilt are the folders that other people share with your mailbox, expandable per person.

  1. Click Mit mir geteilt (Shared with me). The node expands and shows one entry for each sharing person with the part of the address before the "@", for example "dirk.vater" (tooltip "Geteilt von [Adresse]" (Shared by [address])).
  2. Click the person. Their shared folders appear below (tooltip "[Ordner] — geteilt von [Adresse]" ([folder] — shared by [address])), with the number of unread messages.
  3. Click a folder. The list shows its contents, and the mailbox selector automatically switches to that person.

  • Mit mir geteilt (Shared with me) and the person entries contain no messages themselves. A click only expands or collapses them; by default they are collapsed.
  • They are not a target for moving or dropping messages.
  • The state (expanded or collapsed) is saved in the browser.

Permissions: who sees and may do what

  • Access to INGOS Mail: your company's administration decides who may open the app. Access to the app is enough for reading; actions that change something (mark as read, flag, move, delete, set categories, send, empty folder) also require the permission to make changes.
  • Shared folders: what is allowed in a shared folder (read only, or also change and delete) is set by the person when sharing. The mail server checks these permissions on every action.
  • Only your own link: only the administration links or unlinks other people's mailboxes.

If an action in a shared folder is rejected, ask the person who shared the folder for extended permissions.

Common messages

  • "Dieses Postfach ist für dieses Konto nicht freigegeben." (This mailbox is not shared with this account.): the action is not allowed for your account, for example because a share was withdrawn. Reload the app via Aktualisieren (Refresh) in the header bar.
  • "Der Mailserver hat den Vorgang nicht angenommen." (The mail server did not accept the operation.): the mail server rejected the action.
