How to configure your Apple iPhone or iPad to sync with your Zimbra mailbox

There are two ways to configure your iPhone or iPad Mail application to sync to your IAS email account—using an ActiveSync connection or using a standard IMAP connection. An ActiveSync connection pulls in your calendar and contacts in addition to your email. An IMAP connection can sync email messages only.


Please follow the instructions below to configure your iPhone or iPad Mail application to use an ActiveSync connection for email, calendar, and contacts syncing.

Instructions for configuring the Mail application to use IMAP are also available.

1.  From the Home screen go to Settings > Mail, Contacts, Calendars.

2.  Select Add Account.

3.  Select the option for Microsoft Exchange.
