Creating and editing appointments

Appointments are created with Neuer Termin (New appointment), directly in the grid or from an email. This article describes quick create, the appointment window with all its fields, the detail window, editing, moving and deleting, and the right-click menu.

Requirement: at least one writable calendar. Without one, the Neuer Termin (New appointment) button is missing, and the N key reports Kein beschreibbarer Kalender (No writable calendar) – „In diesem Postfach lässt sich kein Termin anlegen.“ (No appointment can be created in this mailbox.)

1. Neuer Termin (New appointment) in the navigation or the N key: opens the full appointment window (see below).
2. Dragging in the grid (day and week, mouse or pen only): press on a free area and drag downward while holding the left mouse button. A preview block shows the period, for example „10:00 – 11:45“, in steps of 15 minutes (at least 15 minutes). When you release, quick create opens.
3. Double-click on a free area in the grid (day and week): one-hour appointment starting at the half hour you clicked, with quick create.
4. Double-click in the „ganztägig“ (all-day) row (day and week): all-day appointment on that day, with quick create.
5. Double-click in a month cell: appointment with a time (not all-day), one hour from 09:00, on today from the next full hour, with quick create.
6. Als Termin anlegen (Create as appointment) on an email (see below).

The writable calendar you used last is preselected, otherwise the main calendar, otherwise the first writable one.

1. Create the appointment in the grid as described above. The small Neuer Termin (New appointment) window appears, and a dashed block is shown in the grid.
2. Type the title in the Titel (Title) field; the cursor is already in it.
3. Enter or Speichern (Save) creates the appointment. The reminder is set to 15 minutes before.

Elements:

• Header: „Neuer Termin“ (New appointment) with the calendar color, below it the period, for example „Donnerstag, 12. November 2026 · 10:00–11:45“ or „… · ganztägig“ (all-day).
• Titel (Title): required. If empty: „Speichern nicht möglich“ (Cannot save) – „Bitte einen Titel angeben.“ (Please enter a title.)
• Kalender (Calendar): name of the calendar in which the appointment is created (display only).
• Weitere Angaben (More details): opens the full appointment window with title and time.
• Speichern (Save): creates the appointment.

The window opens next to the appointment, on a phone as a sheet from the bottom. The form scrolls; the header and footer stay in place.

1. Enter the Titel (Title).
2. If needed, adjust Ort (Location), Ganztägig (All-day), Beginn (Start) and Ende (End).
3. Fill in further fields (see list).
4. Choose Speichern (Save). Termin angelegt (Appointment created) or Termin geändert (Appointment changed) appears.

Fields in the order of the window:

• Titel (Title): required, up to 500 characters. Enter in the title saves. If empty: „Bitte einen Titel angeben.“ (Please enter a title.)
• Ort (Location): free text, placeholder „Ort oder Adresse“ (Location or address), up to 500 characters.
• Ganztägig (All-day): switch; hides the time fields. When switched on, Ende (End) shows the last day. When switched off, the previous times return, otherwise 09:00–10:00; the end is at least one hour after the start. Default: off (except when created from the all-day row).
• Beginn (Start, date) and Uhrzeit (Time): time in steps of 5 minutes. Changing the start moves the end along; the duration stays.
• Ende (End, date) and Uhrzeit (Time): for all-day appointments the last day (inclusive). If the end is before the start (for appointments with a time, also if it equals the start): „Das Ende liegt vor dem Beginn.“ (The end is before the start.) If a value is missing: „Bitte Beginn und Ende angeben“ (Please enter start and end).
• Kalender (Calendar): selection of the writable calendars; only appears if there is more than one. The dot in the header takes on its color. Locked when editing: an existing appointment cannot be moved to another calendar.
• Kategorien (Categories): appears if categories exist or the appointment has some. Shows the categories as colored pills or „Keine“ (None). Kategorie wählen (Choose category) or Ändern (Change) opens the „Kategorie“ (Category) menu with a check mark per category; if the appointment has categories, Alle Kategorien entfernen (Remove all categories) appears at the bottom. Up to 20 categories per appointment. See Categories.
• Wiederholen (Repeat): Nie (Never, default), Täglich (Daily), Wöchentlich (Weekly), Monatlich (Monthly), Jährlich (Yearly); details in Recurring series and invitations.
• Erinnerung (Reminder): Keine (None), Zu Beginn (At start), 5 Minuten vorher (5 minutes before), 10 Minuten vorher (10 minutes before), 15 Minuten vorher (15 minutes before, default for new appointments), 30 Minuten vorher (30 minutes before), 1 Stunde vorher (1 hour before), 2 Stunden vorher (2 hours before), 1 Tag vorher (1 day before), 2 Tage vorher (2 days before), 1 Woche vorher (1 week before). If an existing appointment has a different value (for example 3 hours), it is added to the list.
• Teilnehmer (Attendees): invite people, see Recurring series and invitations.
• Konferenz-Link (Conference link): address of an online meeting, must start with „https://“, up to 1000 characters. Otherwise: „Der Konferenz-Link muss mit https:// beginnen.“ (The conference link must start with https://.) An empty field removes the link. In the detail window it becomes the Beitreten (Join) button.
• Notizen (Notes): description, multi-line, up to 20,000 characters.
• Abbrechen (Cancel): closes without saving.
• Speichern (Save): saves; locked while saving.

Closing behavior: clicking outside the window only closes it if nothing was changed. With changes, it stays open and the footer shakes briefly. Save changes with Speichern (Save) before closing.

Messages when saving: Termin angelegt (Appointment created), Termin geändert (Appointment changed). On an error, Speichern nicht möglich (Cannot save) with the reason, for example „Ungültige Teilnehmer-Adresse: …“ (Invalid attendee address), „Unbekannte Kategorie.“ (Unknown category.), „Dieses Postfach ist für dieses Konto nicht freigegeben.“ (This mailbox is not shared with this account.) or „Der Mailserver ist gerade nicht erreichbar.“ (The mail server is currently unreachable.)

1. In the email view, right-click a message or open ⋮ in the reading pane.
2. Choose Als Termin anlegen (Create as appointment).
3. The calendar opens with the „Neuer Termin“ (New appointment) window:
   • Titel (Title) = subject of the message (without a subject: „(ohne Betreff)“, no subject).
   • Notizen (Notes) = „Von: …“ (From), „Datum: …“ (Date), „Betreff: …“ (Subject) and the message text (together at most 8000 characters).
   • Beginn (Start) = next full hour, duration one hour.
4. Adjust the time and other fields and choose Speichern (Save).
