iPhone redownload mail from Exchange

IPhone strange behavior found today. When you synchronize mail Exchange 2003 activesync iPhone at certain moments starts to download the mail again. Once out of ideas, I tried to capture traffic using Wireshark and found that iPhone redownload mail when it receives a proposal to change the password to the user. That is, users and iPhone Exchange 2003 should change the password for two weeks before password expiration to avoid constant rebooting mail.
The article http://support.microsoft.com/kb/292589 says that the proposal to cancel the password change notification can not be canceled.

iPhone sends a synchronization request mail
Exchange 2003 server offers change password
and further there is a full load mail.
