My firm is running Windows 2000 AD, Exchange 2000 Enterprise and Blackberry Enterprise Server 4.0. We have a mailbox called "helpdesk" where users will send helpdesk requests. Since our IS deparment does not have a way to monitor the helpdesk 24/7, is there a way to configure this "helpdesk" mailbox to forward emails to our Blackberries ONLY after normal working hours? I'm looking at 6:00pm-5:00am during the week and all weekend long. Any suggestions would be apprciated.
