5. Creating forwarding mailboxes
Custom recipients, such as mail-enabled users, don’t normally
receive mail from users outside the organization because a custom
recipient doesn’t have an email address that resolves to a specific
mailbox in your organization. At times, though, you might want external
users, applications, or mail systems to be able to send mail to an
address within your organization and then have Exchange forward this
mail to an external mailbox.
Tip
You can send and receive text messages using Outlook Web App in
Exchange 2013, or you can send text messages the old-fashioned way. In
my organization, I’ve created forwarding mailboxes for text-messaging
and pager alerts. This simple solution lets managers (and monitoring
systems) within the organization quickly and easily send text messages
to IT personnel. In this case, I’ve set up mail-enabled users for each
text messaging email address, such as [email protected],
and then created a mailbox that forwards email to the custom recipient.
Generally, the display name of the mail-enabled user is in the form
Alert User Name, such as Alert William Stanek. The display name and email address for the mailbox are in the form Z LastName and AE-[email protected], such as Z Stanek and [email protected],
respectively. Afterward, I hide the mailbox so that it isn’t displayed
in the global address list or in other address lists; this way, users
can see only the Alert William Stanek mailbox.
To create a user account to receive mail and forward it off site, follow these steps:
-
Using Exchange Admin Center, create a mail-enabled user. Name the account Alert User Name, such as Alert William Stanek. Be sure to establish an external email address that refers to the user’s Internet address. -
Using Exchange Admin Center, create a mailbox-enabled user account
in the domain. Name the account with the appropriate display name, such
as Z Stanek, William. Be sure to create an Exchange mailbox for the
account, but don’t grant any special permission to the account. You
might want to restrict the account so that the user can’t log on to any
servers in the domain. Optionally, hide this mailbox from address lists. -
Using Exchange Admin Center, access the properties dialog box for the mailbox user account (see Figure 7).
-
On the Mailbox Features page, select the View Details option under Mail Flow. This displays the Delivery Options dialog box. -
In the Delivery Options dialog box, select the Enable Forwarding check box and then tap or click Browse. -
In the Select Recipient dialog box, select the mail-enabled user you
created earlier and then tap or click OK twice. Tap or click Save. You
can now use the user account to forward mail to the external mailbox.
