I wanted to allow other users full access to an email account “info”. This is a generic account shared by a few users. In SBS 2003, it was a simple click on the user in Active Directory, and edit a property. In Small Business Server 2008 (or Exchange Server 2007) it’s a little more complicated…first go to the Exchange Management Console (Start – Programs – Exchange 2007). Click on the EMC…then paste the following command into the free text console.
Add-MailboxPermission -Identity “Info” -User John -Accessright Fullaccess -InheritanceType all <ENTER>
Change the usernames as you like. In the example above I am adding John to have rights to the Info account. You can use the cursor keys to move back to allow you to edit the command.
