User has Outlook 2010 and 5 additional mailboxes added to Outlook account settings. She is the only user who manages these mailboxes. When the user moves emails that have been read/replied to, to sub folders within the additional mailbox in her Outlook, it is fine. Once she closes Outlook and restartes the next day, the emails that she has moved to sub folders are back in the additional mailbox inbox as if they have not been processed at all.
The additional mailboxes are not cached.
