Time Based Restrictions To Exchange 2003 OWA

[ICTNUT]

Hi All,

 

I am enableing access for our students to OWA 2003 and wondered if anyone new of a way to restrict access to thier email based on time.

 

I have seen it done once before, but this was a couple of years ago and I can't remember how it was done.

 

I am wanting to restrict so that they can only access before school, breaks, lunches, and after school as this will stop the mindless emailing back and forth between classes when they should be working.

 

Any ideas gratfully received......
