i can see many users' free busy schedule but cannot see some users' free
busy schedule

of course i am sure there are records in their schedule.

what's wrong?

They are are in the same Exchange 2007 database and should be applied same
settings.

as i remember, there is a command line to rebuild individual free busy
schedule

what are the causes? by migration of Exchange 2003 to 2007?

is it stable to rebuild once?

i cannot afford to keep monitoring all outlook accounts cos too many.

sorry in advance for long question.

thanks a lot.
