Certain mailboxes cannot be moved from an Exchange Server 2007 server to an Exchange Server 2010 server

When you try to move mailboxes from a Microsoft Exchange Server 2007 server to a Microsoft Exchange Server 2010 server, certain mailboxes cannot be moved. Additionally, the following event is logged on the Exchange Server 2010 server:

Log Name: Application
Source: MSExchange Mailbox Replication
Event ID: 1100
Task Category: Mailbox Move
Level: Error
Keywords: Classic
Mailbox move for '<mailbox name>' (<GUID>) has failed.Error code: -2147221233MapiExceptionNotFound: Unable to synchronize manifesthr=0x8004010f, ec=-2147221233

This problem occurs when the mailboxes have been previously migrated by using third-party tools and the ptagCn property has been missed.
To resolve this problem, install the following update rollup:

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
