The Exchange 2007 mobile device idle timeout policy associated with the Exchange 2007 service will be adjusted to reflect the update in the UBC Information Security Manual from 10 minutes max to 30 minutes max.
“3.7.3 Exception – Mobile devices must be: Configured to lock the screen automatically, after no more than 30 minutes of inactivity, with password protection”
The UBC Information Security Manual is available here: http://www.it.ubc.ca/service_catalogue/information_security/security/security_policies.html
After this change, mobile device users will have more options available for setting the idle timeout on their phone. By default it will be set to 30 minutes, with the exception of iPhones which have a device limitation that limits them to 15 minutes.
