I recently purchased Iphone 4s. Tried sync up email with I phone, Now on my desktop when it it receives mail i get Outlook error 0x8004210e and it won't receive any messages untill i turn email off on Iphone. I understand that the i phone is logged on to the server not letting the outlook get messages off of the server. How do i remedy this problem and still get emails automatic pushes on the iphone????? The kicker is i never had this problem with my B-Berry, every thing sent and received perfectly. Thanks for the help in advanced!
