Hi, As the above said, you can create a transport rule to let users only receive emails from specific persons, which you can refer to the link: http://technet.microsoft.com/en-us/library/bb124737.aspx As for disabling the mailboxes during business hours, I think you need to disable the transport rule manually or you can schedule a powershell task using Task Scheduler running the specific time of every week. And you can refer to the following: 1. Click Start->All Programs->Accessories->System Tools->Task Scheduler 2. Refer to the article ‘Creating Scheduled Tasks for Exchange 2010 PowerShell Scripts’ to create a powershell task 3. Note that the trigger time can be setup ‘Weekly’according to your demand, the start time is set to A and the script is set to Disable-TransportRule “transportrulename” 4. You need to create another task to enable the transport rule at the right period 5. Note that the trigger time can be setup ‘Weekly’according to your demand, the start time is set to B and the script is set to Enable-TransportRule “transportrulename” If you encounter any difficulties in the above steps, please let us know.

Hi everyone, I need your help for this. I was wondering if it is possible to set an user restriction that disable the mailbox during business hours or just allow to receive emails just from certain people. I work for a school and right now all the students are using the email as a chat system during the clasess hours so the teachers are requesting me to block the email access during this time frame or set a policy or something that just allow them to receive emails from the staff and teachers group during this time. We have Exchange 2010 server. Thank you for your help

You could create a rule that (for example) says that messages from GROUP (the student body is presumably in a DL) are simply dropped without an NDR back to the sender. Or you could send an NDR. Or you could send them for moderation. Really, I dont care too much what kind of rule you create, just take a look through the wizard and create one that fits what you want to happen to emails during school hours. Once youve done that your next trick is to use PowerShell to enable and disable the rule. Link: http://technet.microsoft.com/en-us/library/bb267004.aspx helps you do that. And then, of course, its not a leap to enable and disable the rule on a schedule (enable it at 8am, disable at noon, enable at 1pm and disable the rule again at 4pm). That would simply achieve your goals. There are probably a dozen more ways with increasing levels of automation and slickness.

Nothing straight forward I can think of. What you might be able to do is use transport rules. Create a DG and put all staff in there. Can create another one with all pupile in there. Then create a transport rules which stops email between all pupile and enble this on your HUB server with an excpetion of the staff DG. When they are allowed to use email disable this rule. However transport rules can take time to kick and depends on AD replication too. If you have a single AD site then more likely it will be quick. You may also have to restart the transport service on the HUB server to to speed up the rules when you enable/disable. http://technet.microsoft.com/en-us/library/dd638183.aspxSukh
