Missing Out of Office menu on Blackberry 9650

I was able to restore the option for a user by deleting the Desktop CMime and DesktopSync service books from the device. Then clicking to resend the service books from the Blackberry Enterprise Console. I had read some forums that said to upgrade the Blackberry, the specific Blackberry the user was having a problem with was running the latest software from Verizon which was 6.0.0.719 (Platform 4.4.0.560).
