We have the following situation. A customer of ours got re-branded and has therefore now a new domain name. On the email server (Exchange 2010) we added the new domain and for every user we created a new email address and set it as the primary. (email@example.com instead of firstname.lastname@example.org) The old email address is still in there as an alias.
Now we have the problem that the iPhones didn't get informed of this change. Sending and receiving emails work fine. But then a user presses reply all and the email was sent to the new email address then he get himself on the send to list too.
Is it possible to somehow enforce the change of the email address from the server side? I don't want to touch 50 iPhones to make such a change.
