How can a school use the facilities in Outlook 2007 to co-ordinate its
classrooms?

There are several classrooms.

For any given hour, a teacher/group/course combination is or is not
assigned to a particular classroom.
The "teacher/group/course" have recurring meetings at the same time,
in the same room, on particular days, for a given number of weeks.

(Sounds v close to Outlook Calendar, so far...

Lets say 3 classes are in progress at the same time, that flags a
"conflict" in outlook. (sort of, you cant be in 2 places at once sort
of thing.)

But the school has lots of classrooms, and teachers... so, how could
this be done.

If there are any nifty tricks that can be employed whilst trying this,
please say
