Symptoms

Consider the following scenario:

  • You have two domains (domain A and domain B) in a Microsoft Exchange Server 2010 environment.

  • You deploy an Exchange Server 2010 Mailbox server in domain A, and then you create a user account in domain B.

  • You try to grant the user permissions to a mailbox in domain A. To do this, you run the Add-ADPermission cmdlet and specify a global catalog server that is in domain B as the domain controller.

In this scenario, the cmdlet fails, and you receive the following error message:

User wasn't found. Please make sure you've typed it correctly.
+ CategoryInfo : InvalidArgument: (:) [Add-ADPermission], ManagementObjectNotFoundException
+ FullyQualifiedErrorId : Error ID,Microsoft.Exchange.Management.RecipientTasks.AddADPermission

Cause

This issue occurs because the Exchange server does not use the specified global catalog server when an Active Directory session is created after the role-based access control (RBAC) scope verification process is complete.

To resolve this issue, install the following update rollup:
