How do I set up calendar and address book synchronization via CalDAV/CardDAV?

Want to synchronize your calendar and address book from Cloud Office with one or more devices? In this article, we’ll show you how.

Calendars and address books from Cloud Office can be synchronized with any device or application that supports CalDAV or CardDAV.

CalDAV stands for Calendar Distributed Authoring and Versioning and is a network protocol for synchronizing calendar data. CardDAV performs the same task for address books and the contact details they contain.

Android

For Android devices, the Google Play Store offers various applications for CalDAV/CardDAV synchronization. We recommend using the “DAVx5 Select” app. It was developed specifically for Cloud Office and is free of charge for our customers.

Install the app

To install and set up the app, follow these steps:

1. Download the app from the Google Play Store: DAVx5 Select
   Note: In the Google Play Store, there are two apps with almost the same name: “DAVx5 Select” and “DAVx5”. Make sure to download “DAVx5 Select”. The other app is subject to a fee.
2. Open the app.
   → You will see the homepage of the app.
3. Start the setup process.
   
4. If you like, you can sync your tasks with one of the suggested apps.
   
5. Give the app permission to access notifications, calendars, and contacts. Without this permission, the data cannot be synchronized.
   
6. Allow the app to synchronize the data regularly and complete the setup process.
   

→ You have successfully set up the app.

Establishing a connection

Now connect your e-mail & Cloud Office account:

1. Click “Add account”.
   
2. Select “Log in with URL and user name” and click “Continue”.
   
3. Enter the following details and then click “Login”:
   
   
   • Base URL: https://carddav.hostpoint.ch/ (address book) or https://caldav.hostpoint.ch/ (calendar)
   • Username: The same e-mail address that you use to log into Cloud Office, e.g. your-name@your-own-domain.ch
   • Password: Password for your e-mail account
4. Select whether you want to set up contact groups as separate contacts or as categories.
   Note: This setting is not relevant for Hostpoint customers, as we do not offer contact groups.
   
5. Click “Finish”.
   → The account has been set up.
6. Now decide which calendars and tasks (“CalDAV” tab) and address books (“CardDAV” tab) you want to synchronize with your device.
   

→ The selected calendars and address books will now be synchronized with your device. For example, if you now open your device’s default calendar app, you should see your new account and the corresponding calendar entries.
