Warning of undefined recipient type of a user after the linked mailbox is moved from an Exchange Server 2007 forest to an Exchange Server 2010 forest

Symptoms

Consider the following scenario:

• You create a remote legacy move request to move a linked mailbox from a remote Exchange Server 2007 forest to an Exchange Server 2010 forest.

• The move request is finished successfully.

• You try to manage the mailbox from the remote Exchange Server 2007 forest. For example, you run the Get-recipient cmdlet in the remote Exchange Server 2007 forest to manage the mailbox.

In this scenario, you receive the following warning message:

Warning:
Object Domain/Users/LinkedMailbox has been corrupted and it is in an inconsistent state. The following validation errors have occurred:

Warning:
The value of property 'RecipientTypeDetails', 33554432, is not defined in the Enum type 'RecipientTypeDetails'.

Notes

• The value of property "RecipientTypeDetails" should be 128. This means that it is a Mail User type.

• The value of property "RecipientTypeDetails" 33554432 means that it is a Linked User type.

Cause

This issue occurs because the Mailbox Replication Service (MRS) stamps the recipient type of the user as Linked User if the user’s mailbox is a linked mailbox. This recipient type cannot be recognized by the remote Exchange Server 2007forest.

Resolution

To resolve this issue, install the following update rollup:
