Error: 'Some documents were not archived...' when trying to archive

In Lotus Notes®, when you attempt to archive documents or stationery, you receive the following error message:

"Some documents were not archived because they had already been pruned. See the archive log for additional details."

This was determined not to be a software problem and Notes is working as designed.
Relating to Stationery:

Stationery is a special type of document and at this time, it is not intended to be archived. If you do not want to currently use the stationery but want to preserve it for possible later use, then select it from the Stationery folder (Tools --> Stationery) and cut and paste it into your archive database.

The message occurs when the Archive Criteria setting, "How do you want to clean up documents in this database?," (File --> Database --> Properties --> Archive Settings --> Settings panel) is set to "Reduce the size of documents in this database" with either of the following options selected:

-- Remove attachments, leave summary.
-- Remove attachments, leave summary and 40K.

These settings reduce (prune) the size of documents during archiving and a summary document is left in the mail file. Such summary documents are not eligible for complete removal via archiving. When the setting, "Reduce the size of documents in this database", is selected, summary documents will not be archived. As a workaround, you can cut and past the summary document from your mail file into your archive database file.

NOTE: Cutting and pasting the document will result in it having a new NoteID and Document Unique ID (UNID) because a portion of the document was previously moved to the archive database. This is working as designed.
