iPhone and iPad Configuration Instructions for ActiveSync

The Zimbra service was retired on December 31, 2015.

There are two ways to configure your iPhone or iPad Mail application to sync to your Stanford 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.

The easiest way to set up Zimbra Email and Calendar on your iPhone or iPad using an ActiveSync connection is to use Mobile Device Manager (MDM). University IT strongly recommends using MDM. If, however, you are unable to install MDM please follow the instructions below to configure the 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.

If you have migrated to Office 365, please use the configuration instructions on the Office 365 site.
