Server 2008 password policy lockout

I need to implement a password policy for a network, this includes a lock out policy. I am wondering how admin's are addressing a lock out policy. If for instance I set a lockout policy to lock the account for 30 minutes after 3 invalid login attempts then if the user changes their password but fails to change it in email on their phone then the phone will obviously try to connect to the server with the wrong password and lock out the account.
Any suggestions

I usually leave mine to 0, so that the change is instantaneous.

I'm not sure what you mean about it being instantaneous how does this relate to my question about the phone locking out the account?

If you are only concerned about the phone's that are using active sync you can create or modify the default "Exchange ActiveSync Mailbox Policy".

- Open the EMC
- Expand Organization Config, select Client Access
- Right click the Default Policy (or create a new one), select Properties
- Click on the Password tab
- Change the Number of failed attempts to something higher then your password policy in AD
