Getting started with Zimbra enterprise email

Connect to your Kualo Zimbra enterprise email via webmail, a desktop client, or a mobile device using this quick-start guide.

3 min read Updated 14 Jun 2026

This guide covers the basics of connecting to your Zimbra enterprise email with Kualo, whether you prefer webmail, a desktop client, or a mobile device.

Accessing via webmail

The quickest way to check your email is through webmail - all you need is a browser and an internet connection. Go to:

https://webmail.kualo.com

Log in with the email address and password from your welcome email.

Zimbra webmail comes in two styles, and you can switch between them freely once you are logged in:

  • Modern is the default. It is a clean, fast interface that adapts to any screen size, so it works equally well on a computer, tablet, or phone. You can also install it as an app on your device straight from the browser.
  • Classic is the older, more traditional interface. Some long-time users prefer it, and it offers a few advanced options not yet available in Modern.

To switch between them, open Settings in the Modern client, or Preferences in the Classic client, and choose your preferred default. The change takes effect the next time you log in.

Setting up desktop clients - email only (Standard plan)

If you are on the Professional plan or higher, skip to the Exchange section below.

For email-only access, we recommend IMAP rather than POP3. With IMAP, all your email is stored centrally on the server, so any change you make on one device - reading, deleting, moving - is reflected everywhere else automatically.

Use the following settings in your mail client:

Setting Value
Incoming (IMAP) server webmail.kualo.com
IMAP port 993
IMAP security SSL (required)
Outgoing (SMTP) server smtp.protectedservice.net
SMTP port 587
SMTP authentication Required
Username Your full email address
Password Your email account password

Setting up desktop clients - Exchange support (Professional plan and higher)

If you are on the Professional plan or higher, your account includes full Exchange interoperability. Add the account in your mail client as an Exchange account using the details below:

Setting Value
Exchange server webmail.kualo.com
Username Your full email address
Password Your email account password

For step-by-step instructions in Outlook, see Setting up a Zimbra Exchange email address in Microsoft Outlook.

CalDAV and CardDAV (contacts and calendar sync)

If you want to synchronise your contacts and calendar without using Exchange, you can use CalDAV and CardDAV - open standards supported by most modern mail and calendar apps, including Mozilla Thunderbird.

Use the following server addresses:

Protocol Server address
CardDAV webmail.kualo.com:443
CalDAV https://webmail.kualo.com/dav/Username/CalendarName

Replace Username with your email address username and CalendarName with the name of the calendar you want to synchronise.

Most modern desktop and mobile clients support CalDAV and CardDAV natively. Check your client's account settings before installing any third-party plugin.

Mobile devices

Because the Modern webmail interface works on any screen size and can be installed as an app, it is the easiest way to use Zimbra on a phone or tablet. Open https://webmail.kualo.com in your browser and, if you wish, use the "Add to Home Screen" option to install it.

If you would rather use your device's built-in mail app, set it up with the IMAP and SMTP settings in the email-only section above. On the Professional plan or higher, you can instead add the account as an Exchange account, which also syncs your contacts and calendar.
