Apple Support has posted the first of (no doubt) many issues with the brand new iPhone OS 3.1:
When using a Microsoft Exchange account on an iPhone or iPod touch, the following error message may appear:
| Policy Requirement The account "______________" requires encryption which is not supported on this iPhone. |
Turns out 3.1 can enforce the Exchange ActiveSync mailbox policy requiring encryption on the device. When that option is turned on by the server admin, only devices that support device-level encryption are allowed to sync Mail, Contacts, and Calendars.
The only workaround is to have your Exchange Server administrator change the mailbox policy to no longer require device encryption.
