You can use the Apple iPhone to access your Zimbra account three primary ways:

  1. Entering Zimbra Mobile settings for email, contact and calendar sync
  2. View Zimbra in the Safari mobile web browser
  3. Entering IMAP/POP3 email settings

Using Zimbra Mobile with iPhones


Entering Zimbra Mobile settings on your iPhone (or iPad/iTouch) will sync your email, contacts and calendars using your carrier's data plan. Note, in order to use this feature you need to be 1) using a Zimbra paid Network Edition account and 2) your administrator must have mobility enabled.


Performing these steps can delete all of the existing contacts on your iPhone. This is a common problem for iPhone users when creating a new ActiveSync account. You should ensure that you have backed up all of your contacts before proceeding.


First click on the "Settings" icon (the gears) and scroll down and select "Mail, Contacts, Calendars." On the next screen you will see and select "Add Account." Choose "Microsoft Exchange"

Next you will need to enter your account information:

  • Email. This is your company email address (eg joe@puppies.net)
  • Password. This is your Zimbra password (the same on used for the Zimbra Web Client)
  • Description. A description for your Account


Once you have successfully set up your account, you should begin to see mail folders contacts and your calendar(s) appear on the device. After, you may choose to edit either global or account-specific settings.

Global settings available affect all your email accounts and is located in Settings / Mail, Contacts, Calendars. Here you can set usability controls such as number of messages, previews, font size and more.

Within this screen you may also select your Zimbra Account and then select "Account Info" to adjust whether you want any of the syncing options changed, how many days of email and which folders you want pushed.

Accessing ZCS using Zimbra Mobile Web Client

All devices with an HTML-compatible browser can access Zimbra email, contacts, calendar, and briefcase using the Zimbra Mobile Web Client.

To use the Zimbra Mobile Web Client, open the HTML-compatible browser (the Safari icon on your iPhone) on your phone and type in the URL of your Zimbra Server with a /m/ at the end of the URL. For example:


Getting Zimbra Email Using IMAP/POP3

You can read your email on the iPhone just like you would with a desktop email client by setting it up for IMAP or POP3 access. This option is available to both free Open Source users and paying Network Edition users.

Note: This method only syncs email messages. To access your Zimbra contacts and calendars, use either Zimbra Mobile Web client in the Safari browser or upgrade to Zimbra Network Edition.


  1. Under Mail settings, select "Add Account..."
  2. Select "Other"
  3. Select "IMAP", "POP3", or "Exchange"
  4. Fill in the "Name", "Address", and "Description" fields
  5. Provide "Host Name", "User Name", and "Password" in the "Incoming Mail Server" section. The iPhone will automatically detect IMAP over SSL if your server requires it. If your server requires a non-default TCP port specification, use the hostname:port format in the "Host Name" field. SSL settings can be adjusted later under the "Advanced" section in the mail account settings.
  6. In the "Outgoing Mail Server (SMTP)" section, provide settings for "Host Name", "User Name" and "Password". As with the incoming mail server, the "Host Name" setting accepts the hostname:port format if the outgoing mail server uses a non-default TCP port.
  7. Save the configuration

Sub-Folders: Setting the IMAP Path Prefix to "INBOX" allows for the browsing of folders child folders of "Inbox", but peer folders such as Sent, Drafts, Trash, and Junk folders are not displayed.

General Notes for Administrators

Accessing Zimbra with "Tethered" Sync Options

It is possible to sync iPhone contacts and calendar using Connector for iSync (Apple) or Connector for Outlook (Windows) or on Linux via iTunes. These options are unsupported by Zimbra and we recommend using Zimbra Mobile instead.

SSL Certificates, the iPhone, and Zimbra Mobile

The iPhone prefers non-selfsigned SSL connections. If you have a self signed certificate, then it would be a good idea to install the iPhone Configuration Utility to deply a self signed certificate on the iPhone: http://www.apple.com/support/iphone/enterprise/

The SSL certificate for an Exchange Active Sync server must have as its primary name the name by which the iPhone clients will address the server. This becomes important in situations where the Zimbra server is being run in a split-horizon DNS environment, because the name by which you address the EAS server must resolve to the same (public) IP address, no matter where you are; this may mean that users who have no name for their Zimbra server which behaves this way will need to add one, and such users will need to make sure that name is primary when they rebuild their cert.

Creating New Mail Notification via SMS

You may wish for the Zimbra server to send you a text message when you receive a new e-mail.

  1. Click Options
  2. Choose Mail
  3. Check "Enable address for new mail notifications"
  4. Type your SMS address in e-mail format form. eg: number@txt.att.net
  5. Click Save

Now the server will text message you when you receive a new message. Text messaging rates may apply.
