Exchange hosted Inbox retains email messages when account access via IMAP moves messages into Exchange folders.

I'm using  Mavericks OS X 10.9 (13A603). Due to various reasons, I need to use Apple Mail to access my work's Exchange account. Tried to use the Apple Mail Exchange client, but it refused to display my company email signature on any email client other than Outlook Windows 2013. I also found that this would not allow me to create folders correctly, so I reverted to IMAP access and this is now handling my signature and folders correctly apart from one issue. 

Moving an email from my inbox to an Exchange folder puts a copy of that message into the folder, and removes it from the IMAP inbox list, however, when I go to webmail or Outlook Mac or Outlook Windows, the message is still in the Inbox. I've allowed it up to three days to update and correctly show an empty inbox, but it doesn't happen. Although the IMAP inbox shows no messages, the Exchange Outlook inbox keeps the messages. 

A) Email arrives in my Exchange hosted, but IMAP client accessed inbox in Apple Mail Version 7.0 (1822). 

B) I move the message from the inbox to an Exchange folder, also using IMAP. 

C) Apple Mail shows an empty inbox, signifying that it's been removed from the inbox. 

D) The message is correctly located in the folder on both the IMAP representation and if I go into the webmail access portal or open Outlook Mac. 

E) However, when I try to view my Exchange inbox via Outlook Mac or PC, or webmail, the inbox is still showing those messages as if they weren't moved. 

There's a thread on the Apple Community (https://discussions.apple.com/message/20428894#20428894) where others are also experiencing the same issue with no resolutions being offered by the community so I decided to post a message about the issue here hoping that someone here may know of a solution. 

Thanks!
