This topic explains how to use the Exchange Management Shell to grant access to a user to open another user's mailbox or a resource mailbox.

Before You Begin

To perform this procedure, the account you use must be delegated the Exchange Organization Administrator role.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.

About Explicit Logon

Explicit logon enables a user to open another user's mailbox or a resource mailbox by using Outlook Web Access. To use this feature, the user must have Full Access permissions to the mailbox to be opened. Full Access does not give the user Send As permission or Delegate access to the mailbox.

When explicit logon is used to open a resource mailbox in Outlook Web Access, there will be a set of options available to manage that resource.

Procedure

To use the Exchange Management Shell to grant full access to a mailbox

  1. To grant full access to the mailbox named TestA to the user named TestB, run the following command:

    Add-MailboxPermission -identity TestA -User TestB -AccessRights FullAccess

To open any mailbox from a URL

  1. Open a Web browser.

  2. Enter the URL for your organization's Outlook Web Access, and then add the SMTP address of the mailbox that you want to open to the end of the URL. For example, to open the mailbox conferenceroom@contoso.com, you would enter <Outlook Web Access URL>/conferenceroom@contoso.com. A mailbox can have more than one SMTP address. You can use any of them to open the mailbox.

  3. Log on by using your user name and password.

Note

To use this procedure, you must have Full Access permissions for the mailbox that you want to open.

To open another user's mailbox or a resource mailbox from Outlook Web Access

  1. Log on to Outlook Web Access.

  2. At the top of the Outlook Web Access window, click your mailbox name to open the Open Other Mailbox window.

  3. Enter the name of the mailbox that you want to open, and then click Open.

Note

To open another user's mailbox or a resource mailbox, your mailbox and the mailbox that you are opening must be Exchange 2007 mailboxes.
