Here is a summarized response from support for those that are curious.
- iOS 7.x devices enrolled on EMM 10.2.8 no longer utilize or verify the expiration of the Portal Cert to receive email. The old Portal Cert information will remain until the device configuration is updated, a new policy pushed or any other action which would refresh the field. Email will function as normal and users will not be required to take any action.
I'll be verifying Friday night after the old cert expires. I'd suggest adding this info into the patch/release notes so other folks like me aren't stressed that it didn't update on the device.
Can you please tell me what happened finally after the 27 june 2014 ? no impact on iOS 7 + devices ?
We will have the same operation on september with EMM 10.2.8 /-;
Thanks in advance,
