Create a Mail Enabled Public Folder with auto reply and forwarding!

From Outlook create a public folder and make it for Mail and Post Items.

Open Exchange System Manager (ESM) and drill down on the left hand side through Admin Group-First Admin Group-Folders-Public Folders. Right click on the folder you have just created in the LEFT pane. When the dialog box opens after you right click, select All Tasks-Mail Enable. You will need to wait a few minutes for Exchange to make the changes.

Next right click on the folder again and choose properties and open the email address tab. Make sure the correct address is now populated. If for some reason the address is not there make sure you do not already have a group or user with the name of the folder you have just created.

Next create an email distribution group that you would like messages forwarded to.

Next in Outlook find the Public folder you have created and right click it to select the properties. In the properties of the folder select the administration tab and choose "Folder Assistant." This is where you create the rules to forward, reply or delete messages.

Select Add rule and pick the type of rule you would like to like to setup.
This example is to forward messages:

Select "Sent To" and select the mail enabled folder we have created, then click the box to forward the message and select your user or group you would like the messages forwarded to.

Adding users in SBS 2008

So you added your users the old school way using Active Directory Users and Computers, now you want to give them access to their PC remotely. Only problem is they don't show in the SBS console. No fear, you can still add a user to the console after you added them to AD.
From the SBS Console-Users and Groups click "Change User Role" and select the radio button "Add user permissions or settings" and select Next. In the next window check the box that says "Display all user accounts in the Active Directory" to show users that do not appear in the window. Select the user you want to add permissions to and click the "Change user role" button. After the process completes the user will now appear in the console, along with that, other changes have taken place. The user is now in many SBS Groups including the RWW and Link group.
You can then edit the user account properties and add a computer for the user to connect to.
