For your convenience we added specific configuration for some of the most used applications. Calendars that support CalDAV will work using a server URL address or your full email address. The server URL address is specific to your domain — instructions on how to find it are below.

The correct server address is domain-specific and can be found in your calendar settings. If you're using a third-party app and the first CalDAV URL doesn't work, try the second CalDAV URL — depending on the app's implementation, one or the other will work.

Microsoft Outlook: 

To extend Outlook with Shared Calendar functionality you can use the Outlook CalDav Synchronizer plugin. Please follow the instructions there to install and set up the plugin.

You will need the following information when setting it up:

1. Username: Enter your inbox.eu username,
2. Password: Enter your POP3/IMAP password,
3. Server Address: Enter your calendar server address (see your calendar settings)

Android:

We are creating our own syncronization for android. It will be available in the closest future.

Till we finished development you can use payment version available in play store or other free application.

1. Open installed application,
2. Click on CalDav (1st option),
3. Server name or URL: your calendar server address
4. Username: (Your inbox.eu email),
5. Password: (Your POP3/IMAP password).

If the app asks you to select an account or vendor type from a list:
1. If available, select Nextcloud.
2. If Nextcloud isn't available or doesn't work, select CalDAV.

iOS (Iphone/Ipad/Mac OS/OS X):

1. Go to Calendar > Add Account... > Add CalDAV Account...
2. Select Account Type: Automatic
3. Email address: Enter your inbox.eu email (username@inbox.eu).

Thunderbird Lightning:

Because Lightning is only a subscription service it can't discover the addresses to the calendars by itself. So address configuration have to be created manually.

1. Right-click in the left pane in Calendar
2. Click New Calendar...
3. Select On the Network.
4. Select CalDAV.
5. Location: Enter your calendar url
6. Click Continue.
7. Username: Enter your inbox.eu full email adress username (username@inbox.eu)

Your inbox.eu calendar should now be shown in the left pane.

Google Calendar:

Google is not interested in communicating with the outside world because they want you to use their software.

Even commercial customers seem to be quite upset about that.

Other Calendars:

Mostly calendars support import calendars by url. Use your calendar url and try to add inbox calendar to other services or try the same idea as was described in Thunderbird Lightning.
