Calendar, Contacts and Tasks
Business Email is not only mail. Your account includes a calendar, an address book and a task list, all of which sync to your phone and desktop using open standards — CalDAV for calendars and CardDAV for contacts.
Everything is available in webmail at https://mail.yourdomain.com:8443/ with no setup at all. The steps below are for getting the same data onto your devices.
What syncs
- Calendar — appointments, recurring events, multiple calendars
- Contacts — your address book
- Tasks — to-do items
- Files — a personal file store, reachable over WebDAV
All of it is stored under your own mailbox and travels with you if you ever leave. There is no proprietary format.
iPhone and iPad
Calendar: Settings → Calendar → Accounts → Add Account → Other → Add CalDAV Account.
Server: mail.yourdomain.com
Username: your full email address
Password: your mailbox password (or an app password)Contacts: Settings → Contacts → Accounts → Add Account → Other → Add CardDAV Account, with the same three values.
If iOS asks for a port, use 8443. If it offers "Advanced Settings", leave SSL on.
macOS
System Settings → Internet Accounts → Add Other Account → CalDAV account (and again for CardDAV). Choose Manual as the account type and use the same server and credentials.
Android
Android has no built-in CalDAV or CardDAV support. Install a sync app — DAVx⁵ is the usual choice and is available on F-Droid and Play. Add a "Login with URL and user name" account:
Base URL: https://mail.yourdomain.com:8443/
Username: your full email address
Password: your mailbox password (or an app password)DAVx⁵ will discover your calendars and address books, and you then choose which to sync.
Thunderbird
Thunderbird finds CalDAV calendars from the same base URL. New Calendar → On the Network, enter your email address and the server, and it will offer the calendars it finds.
Outlook
Outlook does not support CalDAV or CardDAV natively — this is a limitation of Outlook, not of our platform, and Microsoft has never implemented them.
Your options are to use webmail for calendar and contacts, or to install a third-party CalDAV connector for Outlook. We do not recommend a specific one and cannot support it.
If calendar-in-Outlook is essential to your organisation, that is a fair reason to consider Microsoft 365 instead, and we would rather say so than sell you something that will not do what you need.
Use an app password
For anything that syncs continuously, generate a per-device app password in webmail rather than using your main password. Phones get lost, and revoking one app password is far less disruptive than changing your password on every device at once.
Sharing a calendar with a colleague
Sharing is managed in webmail. Note that both people must have a mailbox on your domain — you cannot share with an outside address.
If sync stops
- Check you can still sign in to webmail. If not, it is a password problem, not a sync problem.
- If you are using an app password, check it has not been revoked.
- Remove and re-add the account on the device. CalDAV clients cache aggressively and this resolves most cases.
- Still stuck — open a ticket telling us the device, the app and whether webmail works.
