I do IT support for a user that is connecting to an exchange server using the direct push EAS update.

It seems that if the user goes in to an area with poor data coverage, and the phone loses it's connection with the server, it does not automatically re-establish the connection with the server when it is in a good coverage area.

the user needs to force a sync in the application, then direct push starts working again.

is this a known bug with the EAS update?
it seems that the phone should re-establish the connection once it can.
since it doesn't sync on a schedule, the only way for the phone to reestablish the connection is for the user to manually sync once in order to get direct push working again.
