Domain India Business Email is more than mail. Every mailbox also has a calendar, an address book and a task list in webmail, and the calendar and contacts sync to your phone and computer over the open standards CalDAV (calendars) and CardDAV (contacts). This guide shows how to set them up on each device, and what to do when sync stops.
Calendar, contacts and tasks work in webmail with no setup. To sync to a device, add a CalDAV account for calendars and a CardDAV account for contacts, with server mail.yourdomain.com, your full email address as the username and your mailbox password or, better, an app password. No port number is needed; if an app asks for a URL, use https://mail.yourdomain.com/. iPhone, Mac and Thunderbird support this built in; Android needs a sync app such as DAVx5. Outlook does not support CalDAV or CardDAV on its own.
1. What you get
All of it is stored with your mailbox on the mail platform, and it uses open standards rather than a proprietary format. If you ever move to another provider, your calendar and contacts can come with you.
2. The settings for every device
| Setting | Value |
|---|---|
| Server (calendar and contacts) | mail.yourdomain.com |
| URL, if an app asks for one | https://mail.yourdomain.com/ |
| Port | None needed: the standard secure web port (443) is used |
| Username | Your full email address |
| Password | Your mailbox password, or an app password |
| SSL / TLS | On |
Replace yourdomain.com with your own domain.
Calendar and contacts sync use the standard secure web port (443). Enter mail.yourdomain.com with no port, or 443 if an app insists on one. You don't need the :8443 that appears in the webmail address.
Your domain's DNS records must be published before sync works, because devices connect to mail.yourdomain.com by name. If sync fails on a new domain, check the Domain setup card first; see DNS records for Business Email.
3. iPhone and iPad
Calendar: open Settings, go to the Calendar accounts section, tap Add Account, choose Other, then Add CalDAV Account. Enter:
Server: mail.yourdomain.com
User Name: [email protected]
Password: your app passwordContacts: in Settings, go to the Contacts accounts section, tap Add Account, choose Other, then Add CardDAV Account, and enter the same three values.
Leave SSL on. If the device can't verify the account, check that you typed the full email address and that webmail accepts the same password.
4. Mac
Open System Settings, then Internet Accounts, and choose Add Other Account. Add a CalDAV account for your calendar, then repeat with a CardDAV account for contacts. If asked for an account type, choose Manual, and use mail.yourdomain.com as the server with your full email address and password.
5. Android
Android has no built-in CalDAV or CardDAV support, so you need a sync app. DAVx5 is the usual choice and is available on Google Play and F-Droid.
- Install DAVx5and open it.
- Add an accountand choose Login with URL and user name.
- Enter the details.Base URL
https://mail.yourdomain.com/, your full email address as the user name, and your app password. - Choose what to sync.DAVx5 finds your calendars and address books; tick the ones you want.
- Check your apps.Your calendar appears in the phone's calendar app and your contacts in its contacts app.
6. Thunderbird
In Thunderbird's calendar, choose New Calendar, then On the Network. Enter your full email address as the username and mail.yourdomain.com as the location, and Thunderbird offers the calendars it finds. Add your address book the same way from the address book's option for a new CardDAV address book.
7. Outlook
Outlook does not support CalDAV or CardDAV on its own. That is a limitation of Outlook, not of Business Email.
Your options are to keep using webmail for your calendar and contacts while Outlook handles your mail over IMAP, or to install a third-party CalDAV connector for Outlook. We don't recommend a particular connector and can't support one.
If a shared Outlook calendar is essential to how your organisation works, Microsoft 365 may suit you better, and it is fair to say so before you buy.
8. Use an app password for each device
Anything that syncs all day should use its own app password, not your main mailbox password. In webmail, open Security and create one for each device. Each app password is shown once, so paste it into the device straight away.
Phones get lost. Revoking one app password stops that device and nothing else, so you don't have to change your password on every other device.
9. Moving contacts in and out
In webmail's contacts, Import CSV adds contacts from a CSV file, for example one exported from your old provider, and Export CSV downloads your whole address book. Export before you delete a mailbox, or when a colleague takes over a departing employee's contacts.
10. If sync stops
- Sign in to webmail.If webmail refuses your password too, it is a password problem, not a sync problem; see signing in for the first time.
- Check your app password.If the device uses one, make sure it hasn't been revoked. If the mailbox password was reset, every device using it needs the new one.
- Check the server.It should be
mail.yourdomain.comwith no:8443. - Remove and re-add the accounton the device. Sync apps keep old settings, and a fresh account fixes most remaining cases.
- Still stuck?Open a ticket with the device, the app, and whether webmail works.
11. Where Domain India Business Email fits
Business Email gives each mailbox mail, calendar, contacts and tasks at your own domain, with open-standard sync to phones and computers, and costs less than a full office suite. It has no document editing, spreadsheets or video meetings, so if your team needs those, a suite such as Google Workspace or Microsoft 365 is the better fit. It is priced per mailbox, starting from one; the card shows the live price, excluding 18% GST.
- Priced per mailbox - start with one
- Email at your own domain ([email protected])
- Add and remove mailboxes yourself
- Webmail with calendar, contacts and tasks

You don't need it. Calendar and contacts sync use the standard secure web port, so leave the port out or use 443.
How do I sync my Business Email calendar to an Android phone?

Does Business Email calendar work in Outlook?
Not directly. Outlook does not support CalDAV or CardDAV on its own. Use webmail for your calendar and contacts, or a third-party CalDAV connector for Outlook, which we can't support.
Can I import my contacts into Business Email?
Yes. In webmail's contacts, use Import CSV to add contacts from a CSV file, and Export CSV to download your address book.
Why did my calendar stop syncing?
Usually the password changed or an app password was revoked. Check that you can sign in to webmail, update the password on the device, and if that fails, remove and re-add the account.
