Importing IMAP to Exchange

I recently had to move all the emails from an IMAP account into an Exchange 2010 account.  I did this by exporting everything to a PST and then reimporting it into the newly created Exchange account.  This has worked great for me in the past with POP accounts.

However.....
Now all of the folders that I imported are still "IMAP" folders, rather than standard Outlook/Exchange folders.  Which means that they automatically have a filter applied to display only IMAP elements.  Which means that any new incoming email that is moved into one of those folders disappears from sight unless you manually remove the filter - an action which doesn't remove the filters from subfolders.  Ooops....

Re-exporting the mailbox using a POP connection is not an option; the server does not work properly with POP connections.

This mailbox has several hundred subfolders.  Can anyone offer me advice on how to do one of the following:
1. Re-import the data without retaining the "folder-type" information
2. Change the "folder-type" on an Outlook folder
3. Remove filtering from a folder and all subfolders in Outlook
4. Automatically recreate each folder with the same name but the proper "folder-type" and then move the emails over
OR
5. Manually perform #4 while somehow retaining my sanity

Obviously, any other viable workarounds are also welcome.  Thanks!
