How to create a Linked Mailbox in Exchange 2007?
A linked mailbox is a mailbox that is associated with an external account. Every mailbox must have a user account associated with it. However, the user account that will access the linked mailbox does not exist in the forest where Exchange is deployed. Therefore, a disabled user account that exists in the same forest as Exchange must be created and associated with each linked mailbox.
Make sure that your DNS configuration is correct.
On Tiger.VAN.COM domain controller, start the Active Directory Domain and Trust tool;
Right-Click VAN.COM --Properties --Trust
Click on New Trust button
Trust Name: Terrace.com
Direction of Trust: incoming trust
Sides of Trust: Both this domain and specified domain
Administrative Password for Terrace.com domain
Result:
This domain is VAN.COM, this is you are working on.Create a user account: Kobe in VAN.COM first;
To create a Linked Mailbox, you need to work at USA.Terrace.com domain controller.
Exchange Management Console
New Mailbox -- Linked Mailbox type
New User: Kobe Bryant
Mailbox Settings
Alias:Kobe.Bryant
Database:USA\First Storage Group\Mailbox Database
Example 2:
Create a user account in Van.com, e.g. Andy Wilson
At USA.Terrace.COM:
By Exchange Management Shell
[PS] D:\>$credential=Get-credential
You should provide UPN name, e.g. administrator@VAN.COM.
[PS] D:\>$password=read-host "Enter Password" -asSecureString
Enter Password: *********
[PS] D:\>New-Mailbox -Name 'Andy Wilson' -Alias 'Andy.Wilson' -OrganizationalUnit 'Terrace.com/Users' -UserPrincipalName 'Andy.Wilson@Terrace.com' -SamAccountName 'Andy.Wilson' -FirstName 'Andy' -Initials '' -LastName 'Wilson' -Database 'USA\First Storage Group\Mailbox Database' -LinkedMasterAccount 'VAN\Andy.Wilson' -LinkedDomainController 'tiger.VAN.com' -LinkedCredential $credential
How do you access the Linked Mailbox?
From OWA, e.g. https://USA.Terrace.com/OWA
You must sign in as van\Andy.Wilson instead of Terrace\Andy.Wilson. The Terrace\andy.wilson account is disabled.
When you implement the Linked Mailbox? 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.
If you configure OUTLOOK client, please remember the mailbox and its associated account are in different forests.
