Learn more about connecting to a linked domain controller

 

Topic Last Modified: 2012-10-16

When you create a new linked mailbox for a user in a trusted forest, Exchange has to connect to a domain controller in that forest. It connects to retrieve a list of user accounts from which you can select the master account for the linked mailbox. In other words, the linked master account is the user account in the trusted account forest that’s associated with the linked mailbox in your Exchange organization.

If you or your organization has configured a one-way outgoing trust, where the Exchange forest trusts the account forest, you’ll be prompted for administrator credentials in the account forest so that you can gain access to a domain controller to select a master account for the linked mailbox. However, if you’ve created a two-way trust or have created another one-way outgoing trust where the account forest trusts the Exchange forest, you won’t be prompted for administrator credentials in the account forest.
