Sync Contacts and Calendars using CalDAV and CardDAV How to sync your calendar and contacts across all your devices. With CalDAV and CardDAV , you can keep your schedule and address book perfectly in sync across smartphones, tablets, and desktop applications. These protocols allow you to use your favorite native apps (like the built-in calendar on iOS or Android) rather than being forced to use a specific web interface. Note: Please ensure your email account is an Enhanced mailbox - which supports mobile synchronization features - before beginning. Step 1: Get Your Server URLs You will need a specific URL for your Calendar and another for your Contacts. You can find these directly in your webmail interface: Log into your Webmail . Click on your Profile Picture/Icon in the top corner. Select My Account . Navigate to the Synchronization tab on the left-hand menu. Copy the unique links found under CalDAV URL and CardDAV URL . The URLs generally follow this format: CalDAV: https://yourdomain--com.w.emailarray.com/caldav CardDAV: https://yourdomain--com.w.emailarray.com/carddav Step 2: Add a New Account to Your Device The process is similar across most platforms (iOS, Android, macOS, or Thunderbird). Open your device's Settings or your preferred Calendar/Contact app . Find the option to Add Account . Select Other or Advanced Setup (do not select Google, Outlook.com, or iCloud). Choose CalDAV (for Calendars) or CardDAV (for Contacts). Step 3: Enter Connection Details When prompted for account details, use the Manual or Advanced setup option: Username: Your full email address (e.g., john@mydomain.com). Password: Your email account password. Server URL: Paste the specific URL you copied from your webmail in Step 1. Description: Give the account a name, such as "Work Calendar" or "My Contacts." Click Finish or Save to complete the setup. Your device will now begin the initial synchronization.
