Here is an example of the issue:
An e-mail with 20 attachments is discovered to have a hit in each of its attachments. When we export parent messages using "Append number" when it comes across existing documents, we will get 20 of these e-mails, each containing the 20 attachments. This is expected, but not exactly ideal.
We figure we cannot select the "Don't copy" option because there may be an instance where two .MSG files have vastly different attachments, but the exact same subject line. It will only export one of these because we are "not copying" existing files (same file name).
Is there any way around this? Is there some combination of options that will lead to only exporting 1 copy of a parent level e-mail with the attachment "hits", while being safe and not getting rid of an e-mail with different attachments because it has the same file name?
