Use the Resource Out-of-Policy Requests dialog box to specify the users who are allowed to submit resource requests that don’t meet the resource’s policy configuration.

Use the Master Account tab to view or change information about the master account for the linked mailbox. This tab is available only for linked mailboxes. For instructions on how to create a linked mailbox, see Steps for creating a linked mailbox earlier in this document.
Linked mailboxes are mailboxes that are accessed by users in a separate, trusted forest. Linked mailboxes may be necessary for organizations that choose to deploy Exchange in a resource forest. The resource forest scenario allows an organization to centralize Exchange in a single forest, while allowing access to the Exchange organization with user accounts in one or more trusted forests. The linked master account is the user account that will be used to access the linked mailbox.
From the Master Account tab you can view the current master account or choose a different master account for the linked mailbox. Click the Browse button next to the Linked master account box and then use the Select Objects dialog box to select the user account you want to be used to access this linked mailbox. Select a user account from a forest or domain trusted by the forest or domain where Exchange is deployed.
Use the Mailbox Sharing tab to view or change information about the users who have full access to the shared mailbox. This tab is available only for shared mailboxes. For instructions on how to create a shared mailbox, see Steps for creating a shared mailbox earlier in this document.
Shared mailboxes are generally configured to allow logon access for multiple users. Although it is possible to grant additional users the logon rights to any mailbox type, shared mailboxes are dedicated for this functionality. The user account that is associated with a shared mailbox must be a disabled account. From this page, you can grant permissions to all users that require access to the shared mailbox.
From this tab, you can view or change a list of mailbox users. These are the users who can log on to the shared mailbox and have full access to the mailbox contents. They can use the mailbox to send and receive messages, manage contacts, schedule meetings, and maintain a task list. You can add or remove mailbox users:
You can use Active Roles to configure Unified Messaging users. Unified Messaging is a technology in Microsoft Exchange Server that combines voice messaging and e-mail messaging into one store, accessible from a telephone and a computer. Unified Messaging puts all e-mail and voice messages into one Exchange mailbox that can be accessed from many different devices. Once a user has an Exchange mailbox, you can configure the user for Unified Messaging. This can be accomplished by using the Active Roles console or Web Interface.
