How to Configure Autodiscover Service for Cross Forest Mailbox Move
|
In one of my previous Articles I had discussed the Auto-discover Service, a new
feature that provides Exchange features like Offline Address Book, Availability Service
and UM, along with very easy and simple configuration of profiles for Office 2007 clients.
When we move user mailboxes across Forests, there are certain tasks that we need
to perform to make sure that users will be able to use the Autodiscover service after
mailboxes have been moved from one forest to another. We will discuss the configuration
required for Autodiscover Service for Cross Forest Moves
What is involved in Autodiscover Service configuration?
Business Scenario:
Source Forest:
- Domain: nitingupta.in
- Email Address: gupnit@nitingupta.in
Destination Forest:
- Domain: newforest.in
- Username: gupnit@newforest.in
Objective:
- To move the user gupnit@nitingupta.in from Source Forest (nitingupta.in) to the destination
Forest (newforest.in) and make sure that Autodiscover service will be able to handle this movement
and be able to work for this scenario.
Solution Prerequisites:
- A trust between both the forests.
- Delegated Exchange Server Administrator role
- Membership in the local Administrators group for the target CAS server.
Steps involved:
- Move the User Mail box (gupnit@nitingupta.in)
- Configure a mail contact account (gupnit@newforest.in) in the source forest (nitingupta.in)
where the mailbox resided prior to the move.
- Configuring the contact (gupnit@newforest.in) in Source forest (nitingupta.in), results in the user
authenticating to original forest (nitingupta.in), redirection using the new e-mail address.
Outlook 2007 client will try to contact Autodiscover service using the new email address (gupnit@newforest.in)
against the new forest.
- Use Exchange Management Shell command to set the mail contact (gupnit@newforest.in) in the source domain (nitingupta.in):
New-MailContact -ExternalEmailAddress 'SMTP:gupnit@newforest.in' -Name 'Nitin Gupta' -Alias 'gupnit' -OrganizationalUnit 'nitingupta.in/Users' -FirstName 'Nitin' ' -LastName 'gupnit'
- After configuration of contact profile in Outlook 2007, when the user connects to nitingupta.in and uses the nitingupta.in
credentials, Outlook 2007 client receives a redirect response from nitingupta.in, that would look something like this
< ?xml version="1.0" encoding="utf-8"?>\r\n
< Autodiscover xmlns="http://schemas.nitingupta.in/exchange/autodiscover/responseschema/2006"> \r\n
< Account>\r\n
< Action>redirectAddr< /Action>\r\n
< RedirectAddr>gupnit@newforest.in\r\n
< /Account>\r\n
< /Response>< /Autodiscover>
Voila!!. The user will then be able to connect to the
Autodiscover service by using this new e-mail address in the newforest.in forest.
Summary:
If tasks are planned and executed properly, users will be able to use the Autodiscover
service after mailboxes have been moved from one forest to another without any hassles.
