Configuring Delivery Restrictions
More often than not,
you will configure delivery restriction settings at the virtual server
level rather than at the mailbox level, but there are times when it is
appropriate to specify delivery restrictions for a specific mailbox or
group of mailboxes that are different from the settings at the server
level. Delivery restrictions can apply to the size of messages sent from
the mailbox, the size of messages sent to the mailbox, and from whom
the mailbox is allowed to receive messages. To configure delivery
restrictions for a mailbox, edit the user’s properties in the Active
Directory Users And Computers console and click the Exchange General
tab, and then click Delivery Restrictions. Figure 22 shows the configuration options available.
You
might need to configure a specific delivery restriction on a mailbox if
you have a customer feedback mailbox, and you know it should be
receiving only text messages. You could prevent messages greater than 50
kilobytes (KB) from being delivered to that mailbox, which would
prevent the flooding of the mailbox by a malicious user with messages
containing large attachments. Or you might need to set a delivery
restriction if you have a mailbox configured to send out automatic
responses to messages it receives. You could configure a restriction of
the sent message size to prevent the mailbox from being used
inappropriately to send other types of messages.
Forwarding Mailboxes to Other E-Mail Addresses
While you can grant
permissions to a mailbox for another user, sometimes it makes more
sense to forward a mailbox rather than have a user monitor two separate
mailboxes. For instance, if an employee leaves the company and his
mailbox needs to remain active for a period of time, you can grant
another user rights to that mailbox. However, a simpler method is to
forward the mailbox to the designated user. Then all messages that come
in to the mailbox are automatically forwarded to the designated mailbox,
so that user gets both her messages and the forwarded messages in one
location (you can tell them apart by looking at whom the e-mail is
addressed to). Another example of when you would want to forward a
mailbox is when a manager needs an assistant to keep track of her e-mail
while she is out of town and without access to the network. The
assistant can be granted permissions to the manager’s Inbox, but then
the assistant will have access to all past messages, too, which is
undesirable. Instead, you can forward the mailbox to the assistant while
also having the messages delivered to the manager’s mailbox, which
accomplishes the goal of allowing the assistant to monitor the manager’s
e-mail without being able to see past e-mails. When the manager
returns, you simply turn off the forwarding of the mailbox.
To configure mailbox forwarding, perform the following steps:
1. | Open the Active Directory Users And Computers console and edit the properties of the user account.
|
2. | Next, click the Exchange General tab, and then click Delivery Options.
|
3. | Under
Forwarding Address, click Forward To, and then click Modify and enter
the name of the user who should receive the messages (or browse Active
Directory). Click OK.
|
4. | The
check box for Deliver Messages To Both Forwarding Address And Mailbox
determines the behavior of the forwarding. If you select it, both
mailboxes will receive new messages as they arrive. If you do not select
it, only the forwarding mailbox will receive new messages.

Moving Mailboxes to Other Servers and Mailbox Stores
As your organization
grows and changes, employees will change divisions or locations.
Depending on the size and complexity of your Exchange organization, an
employee move can result in a situation where he needs to have his
mailbox in a different mailbox store or even on a different server.
Exchange Server 2003 makes it easy to accommodate mailbox moves, and
there are a couple of different ways to accomplish the task.
Moving Mailboxes with the Exchange Task Wizard
If you need to move only a
few mailboxes within the same organization, you can use the Exchange
Task Wizard and choose the Move Mailbox option, which will open the Move
Mailbox page, shown in Figure 23.
In Figure 23,
you see the current location of the mailbox. The Server and Mailbox
Store drop-down lists provide the available options of where to move the
mailbox. In Figure 23,
the mailbox is being moved from the first mailbox store on Server1 to
the first mailbox store on Server2. Once you click Next on this page,
you are prompted to determine how to handle corrupted messages found
during the move, as shown in Figure 24.
The default is simply
to cancel the mailbox move and generate a report. You may decide that
the move should continue anyway and skip the corrupted messages. When
you click Next on this page, you are able to determine when the move
will take place and when the task should terminate if it hasn’t
completed. This is a standard task scheduler page. You can schedule the
move to occur at any time, such as overnight or at a later date, or take
the default choice to run immediately. If you leave the default
setting, the process will begin immediately when you click Next, and you
can monitor the progress. If you schedule the move, the task will be
entered into the Task Scheduler to run as scheduled.
Note
You
can also use Exchange System Manager to start the Exchange Task Wizard.
From the mailbox store, in the Mailboxes container, right-click the
mailbox and choose Exchange Tasks. This starts the same wizard that is
accessed through the Active Directory Users And Computers console. |
Tip
There
are limitations when moving mailboxes with the Exchange Task Wizard.
You cannot move mailboxes between administrative groups unless your
Exchange organization is in Native mode. You also cannot move mailboxes
between Exchange organizations. However, you can do either using the
Microsoft Exchange Mailbox Merge Wizard, even if your organization is
still in Mixed mode. |
