CalDAV Synchronization
Overton.cloud offers synchronization for calendars and contacts across your devices using its DAV server. This guide covers the connection details and platform-specific setup for CalDAV and CardDAV.
Connection Credentials
All configurations use the same details:
| Setting | Value |
|---|---|
| Server | dav.mxroute.com |
| Port | 443 (HTTPS) |
| Authentication | Full email address and corresponding email password |
The base URL used by most clients is:
https://dav.mxroute.com
Clients that ask for an explicit principal or collection path can use the standard DAV discovery paths:
https://dav.mxroute.com/ (account / auto-discovery)
https://dav.mxroute.com/principals/you@yourdomain.com/
https://dav.mxroute.com/calendars/you@yourdomain.com/
https://dav.mxroute.com/addressbooks/you@yourdomain.com/
MX records required
Your domain’s MX records must point to Overton.cloud servers for authentication to work.
Platform-Specific Setup
iOS / iPadOS
Add a CalDAV account through Settings → Calendar → Accounts, select Other, then Add CalDAV Account, and enter the server details:
Server: dav.mxroute.com
Username: you@yourdomain.com
Password: your email password
macOS
The Calendar and Contacts apps have dedicated setup flows under their respective menus. Choose the manual account type and enter the server address dav.mxroute.com with your full email address and password.
Android
Android lacks native support, so we recommend DAVx5, available on the Google Play Store and F-Droid. It accepts the base URL with standard credentials:
Base URL: https://dav.mxroute.com
Username: you@yourdomain.com
Password: your email password
Thunderbird
Set up calendars through the Calendar tab and contacts through the Address Book tab. Both support network-based synchronization using dav.mxroute.com and your email credentials.
Windows
Use a third-party client such as Thunderbird or eM Client, as the built-in Windows applications don’t support these protocols.
Generic Applications
For any compatible app, the same server URL and credentials apply.
SSL/TLS is required
All connections must use SSL/TLS on port 443. Clients that offer an unencrypted option should always be set to require a secure connection.
Use auto-discovery first
Most modern clients only need the base URL https://dav.mxroute.com and will discover your calendars and address books automatically. Only fall back to the explicit collection paths if your client requires them.
