A call was logged to allow some of the employees to access support emails i.e support@workplacesystems.com. How to do it? It is configured using Active Directory. In Active Directory users and computers tool there are Incidental Mailboxes which contains support email. If you right click on that goto properties under Exchange Advanced you can find mailbox rights. Just enter the name of the person who you want to give access to and click check names. Provided the employee is the member of the Domain Users it would get authenticated and allow him to access the specified emails.
In Outlook 2003 the mailbox of the user can be configured by opening Email Accounts in control panel and then opt change email account hence more settings. Goto advanced tab and add mailbox you want to view i.e support in this case.

Then I needed to set up a new Incidental Mailbox called fogbugz@workplacesytems.com. The best way to do without any confusions is to copy one of the existing mailboxes and fill in the details. Then configure the properties as required.
