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

(See below for more 'tethered' sync options to iTunes, etc).

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:


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.

You can find more information on the Next Wiki - Zimbra_Mobile_Installation_and_Setup_for_iPhone Zimbra Mobile for Smart Phones on the iPhone is only available to Zimbra Collaboration Suite Network Edition customers using ZCS 5.0.6 or later and iPhone OS 2.0 or later.

  1. Install iTunes 7.7 or higher and upgrade your phone to the latest iPhone OS, if necessary.
  2. If you already have your Zimbra server running with IMAP/POP3, disable the account in Mail Settings.
  3. Set up a new mail account, selecting "Exchange".
  4. Enter your email address in the form of example@domain.com in the Email field.
  5. Enter your Exchange domain and username (e.g. “domain.com\example”) in the Username box. If you only have one domain, then the domain is not necessary, only the username.
  6. Enter your password in the Password field.
  7. The iPhone will now try to automatically discover your Zimbra server. If this fails, then you will need to enter your server information manually. It will prompt you for this.
  8. Now tap the Home button and go into Mail. You should see your new account appear, and it should show your folders and email messages within a few moments.

You have now finished configuring Zimbra Mobile for Smart Phone on your iPhone.

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. (Thanks to Baylink for this information!)

Acessing ZCS using IMAP/POP3

You can access mail from a ZCS account using IMAP or POP3. This option is available to both Open Source users and Network Edition customers. Note: This method only syncs mail messages. For access to contacts and calendars, use the Zimbra Mobile Webclient.

  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.

Accessing ZCS with the Connector for iSync (Macintosh) (Unsupported)

Note: This method is not recommended. We recommend using the Zimbra Mobile for Smart Phones option instead.

You can use the Zimbra Collaboration Suite Connector for Apple iSync to synchronize your contacts and calendar information between your iPhone and Zimbra Collaboration Suite.

The iSync Connector is used to sync your Calendar and Contacts to your Macintosh (not mail). In order to achieve sync with the iSync Connector and the iPhone, you will need to sync your iPhone to iTunes. To get your mail on the iPhone (in conjunction with this method as opposed to the ActiveSync method), you will need to setup IMAP/POP3 access as well.

The iSync connector is only included in Network Edition products. It can be acquired in the Zimbra Administration Server console.

Accessing ZCS with the Connector for Outlook (Windows) (Unsupported)

Note: This method is not recommended. We recommend using the Zimbra Mobile for Smart Phones option instead. You can use the Zimbra Collaboration Suite Connector for Microsoft Office Outlook 2003 SP1+ to synchronize your contact and calendar information between your iPhone and Zimbra Collaboration Suite. For more information about the Zimbra Collaboration Suite Connector for Microsoft Outlook, refer to the Zimbra Collaboration Suite Connector for Microsoft Outlook guide.

Your Zimbra profile in Microsoft Outlook must be the default profile. Otherwise, iTunes will only sync the default profile to the iPhone. For more information on setting your default profile, click here.

If you do not use the Zimbra Collaboration Suite Connector for Microsoft Outlook, you may only complete a partial sync. While Microsoft Outlook and iPhone will be fully updated, the Zimbra server will not sync anything except email, if you have it set up. In order to fully sync, you must use the Zimbra Collaboration Suite Connector for Microsoft Outlook.

As with Apple's iSync, e-mail is not synced; however, your calendar, and contacts will be synced.

Syncing Zimbra Data on the iPhone using Linux (Unsupported)

The iPhone uses iTunes to sync all information. Apple has not developed a version of iTunes for Linux, thus syncing is not possible. LifeHacker has a tutorial on syncing wirelessly in Linux, but this method is not supported by Zimbra in any way: http://lifehacker.com/388785/sync-your-iphone-wirelessly-in-linux

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.
