If you have shared calendars in Zimbra, you cannot access them using the normal Microsoft Exchange Zimbra sync. Instead, follow the steps below to add a CalDAV account.

  1. Open Settings.

  2. Tap Mail, Contacts, Calendars.

  3. Tap Add Account...

  4. Select Other.

  5. Tap Add CalDAV Account.

  6. In the Server field, enter your Server. Enter your username and password in the "User Name" and "Password" fields, respectively. You can enter anything you want in the Description field.

  7. Tap Next and the account will be added.

To access your calendars, use the Calendar app.

Note: If you previously added your Zimbra account to sync mail and calendars, you will sync some calendars twice. There are two ways to address this:

In the Calendar App itself, select Calendars, then scroll down to the new CalDAV calendars, and then uncheck the duplicate items.




In order to stop syncing calendars through the original account, follow the instructions below.

  1. Open Settings.

  2. Tap Mail, Contacts, Calendars.

  3. Find the original Zimbra mail account and select it.

  4. Move the slider next to Calendars to the off position. If you get a warning about deleting calendars from your device, tap Delete from My iPhone.

Any personal calendars synced through that account will no longer appear in the Calendar app.
