CalDAV — calendar sync
CalDAV is the open standard for calendar synchronization defined in RFC 4791. Connect any CalDAV-capable calendar app to UGMail and your events, reminders, and schedules stay in sync across every device automatically.Compatible clients
- Apple Calendar (macOS, iOS, iPadOS)
- Google Calendar (via CalDAV account type)
- Mozilla Thunderbird with the Lightning / Calendar add-on
- GNOME Calendar and Evolution (Linux)
- Android via DAVx⁵ or similar sync adapters
- Any standards-compliant CalDAV client
Connection details
Configuration steps
Open your calendar app's account settings
Navigate to Settings → Accounts (or Internet Accounts on macOS/iOS) and choose Add Account. Select CalDAV or Other as the account type.
Enter the server URL
Set the server to https://mail.ugmail.co. Some clients label this field CalDAV Server, Server Address, or Account URL.
Enter your credentials
Set the username to your full mailbox email address (e.g. alice@example.com) and the password to your mailbox password.
Trigger discovery
Save or click Next. Your client will query the server for available calendars. Accept the calendars it finds and choose how frequently to sync.
Verify sync
Create a test event in the app and confirm it appears when you reload the calendar from another device or client connected to the same mailbox.
If your client requires a full CalDAV principal URL instead of just the base server, use https://mail.ugmail.co/dav/principals/alice@example.com/ — replacing the email address with your mailbox address.
CardDAV is the open standard for contact synchronization defined in RFC 6352. Connect your address book app to UGMail and every contact you add, edit, or delete stays consistent across all your devices and clients.Compatible clients
- Apple Contacts (macOS, iOS, iPadOS)
- Mozilla Thunderbird (built-in address book with CardDAV support)
- GNOME Contacts and Evolution (Linux)
- Android via DAVx⁵ or similar sync adapters
- Outlook via third-party CardDAV connectors
- Any standards-compliant CardDAV client
Connection details
Configuration steps
Open your contacts app's account settings
Navigate to Settings → Accounts (or Internet Accounts on macOS/iOS) and choose Add Account. Select CardDAV or Other as the account type.
Enter the server URL
Set the server to https://mail.ugmail.co. Some clients label this field CardDAV Server, Server Address, or Account URL.
Enter your credentials
Set the username to your full mailbox email address (e.g. alice@example.com) and the password to your mailbox password.
Trigger discovery
Save or click Next. Your client will discover available address books on the server. Select the address books you want to sync.
Verify sync
Add a test contact and confirm it appears when you refresh the address book from another connected device or client.
If your client requires a full CardDAV principal URL, use https://mail.ugmail.co/dav/principals/alice@example.com/ — replacing the email address with your mailbox address.
On Android, install DAVx⁵ from F-Droid or Google Play. It handles both CalDAV and CardDAV in a single account setup, so you can sync both calendars and contacts with one set of credentials.
WebDAV — file storage
WebDAV (Web Distributed Authoring and Versioning) is defined in RFC 4918 and extends HTTPS to support file operations — creating, reading, updating, and deleting files and directories on a remote server. UGMail exposes WebDAV so you can mount your mailbox storage as a network drive on any desktop operating system or integrate it into automated file management workflows.Compatible clients
- macOS Finder — connect via Go → Connect to Server
- Windows Explorer — map as a network drive
- Linux — mount via GNOME Files, Dolphin, or the
davfs2 kernel module
- Cyberduck, WinSCP, Transmit, Cadaver, and other WebDAV-capable file managers
- Any HTTP client or library that supports WebDAV methods (
PROPFIND, PUT, DELETE, etc.)
Connection details
Configuration steps
Choose your WebDAV client
Open the file manager or WebDAV client you want to use. The steps below are generic — consult your client’s documentation for exact menu labels.
Connect to the server
Enter the server URL https://mail.ugmail.co as the WebDAV address. In macOS Finder, go to Go → Connect to Server and enter the URL. In Windows Explorer, use Map Network Drive → Connect to a website. On Linux with davfs2, add an entry to /etc/fstab.
Authenticate
When prompted, enter your full mailbox email address as the username and your mailbox password as the password. Enable Remember credentials if you want the mount to persist across reboots.
Browse and manage files
Once connected, your UGMail file storage appears as a folder in your file manager. Copy, move, create, and delete files as you would on a local drive.
Automate with scripts
Use any HTTP library to perform WebDAV operations programmatically. The example below uses curl to upload a file.

WebDAV over plain HTTP is not supported. Always use https:// to ensure your credentials and file contents are encrypted in transit.
