Linked Mailbox in Exchange Server 2013 – Part 2

In part 1 we learnt how to create trust and also setup DNS settings for communication. In part two we will be learning how to create Linked Mailbox.

Prerequisites

The account used for creating mailbox should be a member of Recipient Management Group (Minimum). I have used the default Administrator Account.

Scenario

Account forest will have User Account. We will link these account using EAC from Resource Forest.

Figure 2.1 : OU Created by the name Linked Users for identification in Account Forest.

In figure 2.1 an OU has been created to identify Linked users in Account Forest.

Figure 2.2 : EAC.

In figure 2.2 open EAC and select recipients. Under recipients select mailbox and then select Linked Mailbox as shown above.

Figure 2.3 : New Linked Mailbox Wizard

In figure 2.3 the wizard has selected the trusted forest on its own.

Figure 2.4 : Select linked Master Account.

In figure 2.4 select the account which needs a mailbox by selecting browse.

Figure 2.5 : Accounts for selection.

The account are from Account Forest. Will select user account who reside in Linked Users OU as shown in figure 2.1.

Figure 2.6 : Account selected.

In figure 2.6 the wizard says Select the external user account in the trusted forest or domain that you want to associate with the new linked mailbox. The user will use this account to sign in to the linked mailbox.

Figure 2.7 : Resource forest disabled account created inside Linked OU.

In figure 2.7 the final step in which we create an account by the same name which will be disabled by default. As a best practice an OU by the name Linked is being created so that linked account resides there to avoid confusion in future.

Figure 2.8 : Linked Mailbox as seen on EAC.

In figure 2.8 we can see three Linked Mailbox. They also have a different email address based on their identity and domain. Regarding (EAP) we will learn in next part series.
