Microsoft Exchange Active Sync issue when roaming
This is a known bug in the Android OS. A senior AT&amp;T engineer let me know that this is a problem and hopefully it will be fixed soon. 

it is not a AT&amp;T, Verizon or T-Mobile issue. it is a problem with Android  :(

edit: he let me know that there is an app on the google store  called "Touchdown" that is a workaround for this issue.
