This issue occurs because the Managed Folder Assistant uses a global scope incorrectly and does not use a unique identifier to open the mailbox. Therefore, two objects that have the same Simple Mail Transfer Protocol (SMTP) address are returned, and the Managed Folder Assistant does not process the mailbox.
To resolve this issue, install the following update rollup:
