one user can not retrieve email from phone

[richardfu]

I have one user can not hear the email from the IP phone, Text-To-Speech configured for this subscriber, listen voice message on the IP phone no problem, from outlook side, no problem, checked everything looks fine. any idea what happened for this?

Unity 405 UM with Exchange 2003, Callmanager 413.

Thanks

Actually this is system wide problem, other users not reported.

Solution: The unity primary server was out of synch with the exchange message store, restarted the Message Store svc, problem solved.

Thanks Jeff and other posts, do give me lots of clues.
