Word documents and Excel documents are added to the Attachment quarantine box but when I deliver the messages as Administrator from the web GUI the mails are never delivered in the user mailbox.
We use Microsoft Exchange.
 
I had the same issue the last month.
Could you check with "Exchange Management Shell" and command Get-MessageTrackingLog -EventId "DUPLICATEDELIVER" if you see mails in the list ?

You must remove Message-ID field for each mail in Attachment quarantine box with add action object.

> Mail Filter | Action Objects | Add | Header Attribute
Name : Attachment Quarantine (Modify Message-ID)
Comment : Change Message-ID for Remove matching attachments for not have DUPLICATEDELIVER.
Field : Message-ID
Value : (space)

And add this action in your rule wich remove Word documents and Excel documents

I have 1 question:
- Now I found some messages in the logging with EventID DUPLICATEDELIVER is there a way to re-send the mails to the users with a new Message-ID or empty Message-ID. Or is there an option to delete the queue with duplicates.

Thank you for all your help.

I didn't find how to we can release mails detected like duplicate. Peurhaps MS Exchange Engineers know how to do...
