The iPhone currently supports the following security policies from Exchange (note: you must have Exchange Server 2003 SP2 or Exchange Server 2007 SP1 or greater):

  • Remote Wipe
  • Enforce password on device
  • Minimum password length
  • Require alphanumeric password
  • Require complex password
  • Inactivity time in mimutes

When you perform the remote wipe from Exchange, it restores your iPhone to factory default (note: this could take up to an hour).  The gotcha – after you perform remote wipe, be sure to “remove mobile device partnership” with your iPhone; otherwise, the next time you try to sync with Exchange it will wipe (restore to factory default) again . . .
