The patches today will include one for Exchange. According to Research In Motion this patch will break some of the functionality needed for their enterprise product offering.
“this update affects user mailbox permissions by revoking the ‘Send As’ permission in Exchange which has an impact on third party products such as BlackBerry Enterprise Server for Microsoft Exchange. Once applied, this update will prevent users on BlackBerry Enterprise Server from sending email from a BlackBerry or BlackBerry-enabled device, however users will still receive emails on their BlackBerry device. This is due to the BlackBerry service sending emails on behalf of a user when a message is sent via the BlackBerry device.”
