Microsoft Exchange ActiveSync allows wireless contact between corporate users of iPhones and the company's Exchange server. To do this, the company's Exchange server regularly pushes data to the iPhones to keep them current on email, appointments, meetings and contacts. Data is sent using an encrypted SSL connection. Minor configuration changes can be made to the mail syncing schedule and the Exchange folders that users see by default in the message Inbox. Most generic changes can be applied to all email accounts established on the iPhone.

- Avoid the "No limit" option under "Mail days to sync." Depending on the space limitations, setting mail syncing to "No limit" can cause Exchange mail delivery to fail, as well as drain the phone's battery and power sources.
