This document describes an issue seen during the Microsoft Exchange Migration process. When using a Single Inbox, it is not unusual for users to migrate mailboxes between different versions of Exchange.
Occasionally, there might be an issue with old messages that are duplicated for an unknown reason. This can follow an attempt to migrate a mailbox from Exchange 2007 or Exchange 2010 to Exchange 2013. However, the migration can occur between any version of Exchange. After migration, it is possible that some users might report an old message that was present before the migration which duplicates hourly in Outlook. New messages that remain after the migration generally do not duplicate. The problem in this example is that the VoiceMessages folder becomes damaged. In order to fix the problem, it is necessary to locate a low level view of the mailbox and delete the VoiceMessages folder.
Follow these steps to address the issue for a specific user:
