Exchange ActiveSync Proxying for 2007 iPhone users

Experts -

In place now, I have an Exchange 2010/2007 coexistence environment. I have approximately 100 iPhones in the wild.

I am ready to switch DNS and point my Autodiscover and A record for the external URL (ActiveSync included) to the 2010 server. I understand (and have tested) that iPhone users with mailboxes on the '07 server will fail once this is done due to a bug in Apple's software (not supporting EAS 12.1).

Apparently there is a workaround: removing the ExternalURL for the ActiveSyncVirtualDirectory to use proxy instead of redirection.

What I want to know is: Will the IT group for my 100 iPhone users who still have Ex '07 mailboxes have to make any changes to the existing configurations (on the iPhone device) or will it be seamless for those users?

I would like to switch CAS over to 2010 externally and just cannot risk 100 angry apple-phites calling about their mobile email.

Hi,

I would suggest, run through a test lab if you have any. Unless iphone software is smart enough to figure out the change by itself
