iOS 5 Beta issues with Exchange ActiveSync mailbox policy
Apple released their iOS5 OS for developers which is in its Beta version.This release has a known compatibility issue with Exchange ActiveSync if you have enabled “Require storage card encryption” in your Exchange ActiveSync mailbox policy. This setting specifies whether the storage card must be encrypted. Not all mobile phone operating systems support storage card encryption. For now, iPhone and iPad running iOS5 do not support this feature.
A list of EAS policies can be found here: http://technet.microsoft.com/en-us/library/bb123484.aspx
When a user who updated his Apple mobile device to iOS5 Beta tries to sync his email using Exchange ActiveSync, it gives a message “A policy requires you to encrypt the storage card on this device” – (Can’t recall, something similar..)
To resolve this issue:
- Do not update the phone to iOS5. Note that once you update, you cannot roll back the change.
- Configure a new EAS policy which would not require “Require storage card encryption” and add the user to it
- Simply uncheck “Require storage card encryption” from the EAS policy. Consult you InfoSec team before applying this change.
