Share and connect calendars

There are two ways to share your calendars with others:

1. Publish the calendar with a link anyone can subscribe to in their own calendar app
2. Connect external apps over CalDAV — so Apple Calendar, Thunderbird, DAVx5, or Outlook shows your events in their own view

You'll find both under Settings → Calendar sharing.

Publish a calendar

When you publish a calendar, we create a subscription URL that anyone can add to their calendar app. They see the events but can't edit them.

1. Go to Settings → Calendar sharing
2. Under PUBLISHED CALENDARS, find the calendar you want to share
3. Choose a level of detail:
   • Busy times only — others see when you're booked, but not the title or description
   • All event details — others see the title, description, location, and so on
4. Turn on publishing — we'll show a subscription URL
5. Copy the URL and send it to the people you want to share with

Help text in the panel: "Anyone with the URL can subscribe to this calendar in their app. They can't edit your events."

Revoke a publication

Turn off publishing in the same panel — the URL stops working immediately. If you publish again later, you'll get a new URL (the old one stops working for good).

Connect an external calendar app

To open your onmeil.eu calendar in Apple Calendar, Thunderbird, DAVx5 (Android), or Outlook with a DAV extension:

You'll need:

1. An app password — create one under Settings → App connections (or directly from the calendar sharing panel)
2. The Server URL, username, and app password from the Calendar sharing panel

In the CONNECT AN EXTERNAL CALENDAR APP panel you'll see:

Field	What it is
Server URL	The URL your calendar app should connect to
Username	Your email address
Password	Use an app password (not your main password)

Click Copy next to each value to paste it into your calendar app.

Help text: "Use these settings to open your onmeil.eu calendar from Apple Calendar, Thunderbird, DAVx5 (Android), or Outlook with a DAV extension."

Step-by-step setup per app

Under STEP-BY-STEP SETUP you'll find instructions for each client:

• Apple Calendar (macOS / iOS)
• Thunderbird
• DAVx5 (Android)
• Outlook (via DAV extension)

Click the client you use to expand the instructions.

More details in CalDAV setup.

Publishing vs. CalDAV

	Publishing	CalDAV connection
For yourself or others?	Others (one way)	Yourself (two way)
Requires an app password	No	Yes
Can edit	No	Yes
Synced	One time (the recipient refreshes periodically)	Continuously

Use publishing to show your calendar to others. Use CalDAV to open your own calendar in Apple Calendar / Thunderbird, and so on.

Invite a guest to a single event

Want to share just one event, not the whole calendar? Invite them as a guest in the event dialog — see Events. For people without an onmeil.eu account, create a shareable link.
