How Calendar & Contacts Work
Overton.cloud offers calendar and contacts synchronization through the CalDAV and CardDAV protocols. Here’s how the service works and what you need to know before you connect your devices.
Connection Details
Calendar and contacts sync run on a dedicated DAV server. You authenticate with the same credentials you use for email:
| Setting | Value |
|---|---|
| Server | dav.mxroute.com |
| Username | Your complete email address |
| Password | Your email account password |
| Port | 443 (HTTPS) |
MX records required
Your domain’s MX records must be configured to point toward Overton.cloud servers for authentication to work.
Synchronization Capabilities
The service supports syncing calendar events through CalDAV and address books through CardDAV across all of your devices. Changes made on one device propagate to the others through the shared DAV server.
Compatible Devices & Applications
Setup instructions are accessible via the Control Panel for the following platforms:
- iOS / iPadOS
- macOS
- Android (via DAVx5)
- Thunderbird
- Windows (using Thunderbird or eM Client)
Important Limitations
Not integrated with webmail
None of our webmail applications currently connect to or share data with the DAV service. Calendar and contacts run as a separate synchronization service rather than integrating with the webmail interfaces.
If you have substantial calendar or contacts requirements, you may want to supplement Overton.cloud email with a dedicated service such as Google Calendar or iCloud.
For step-by-step setup, see the CalDAV Synchronization guide. You may also find the iOS Mail Setup guide useful when configuring Apple devices.
