Our enterprise will be migrating from Exchange 2007 SP3 to Exchange 2013 CU3 very shortly. Exchange 2013 is set up and I am in coexistance mode currently. Everything is working fine with the legacy redirection, I have tested some mailbox migrations and they work fine. We currently use Mimosa Nearpoint as a third party email archive product.

As part of this migration from 2007 to 2013, we plan on moving away from Mimosa Nearpoint and utilizing the Exchange 2013 Archive Mailbox feature. We will give each user an Archive Mailbox. We have the ability to export the users existing archive out of NearPoint to .PST files and then migrating them directly into the users Archive Mailbox using the "New-MailboxImportRequest -IsArchive" powershell commandlet. This has been tested and works fine with one very important exception.

When I export from Nearpoint, I have to export the entire contents of the archive, I cannot set date ranges. So when I do an export, it also contains the contents of the user's mailbox. I have managed folder policies in place in the Exchange 2007 environment which delete all contents of the mailbox older than 60 days, but when I import the .PST to the archive, it imports ALL items into the Archive Mailbox. So I have 60 days worth duplication of items.

It is my understanding that if I imported the Archive .PST directly into the users production mailbox in the 2013 side, that it would not import duplicate items. I am trying to find out if there is any process which will do the same thing with me importing directly into the users Archive Mailbox.

Yes, it won't import the duplicate items into user mailbox.
When data is imported from a .pst file, it is merged into the existing mailbox. If a message from the .pst file already exists, it will not be imported as a duplicate message.
