MailStore

Supported MailStore file formats (IdClassification.MailStore - Email container document formats (e.g., PST, OST, MBOX, Lotus NSF, etc))

All entries in table below are supported for file format identification.
'X' in "Text" column indicates text extraction is supported for the file format.
'X**' in "Text" column indicates text extraction is supported BUT binary-to-text filtering is used on partially parsed document records.
'X' in "Metadata" column indicates metadata extraction is supported for the file format.
'X' in "EmbeddedItem" column indicates embedded item/attachment extraction is supported for the file format.
'X' in "ContentHash" column indicates a content hash is supported for the file format (see MD5ContentHash and SHA1ContentHash)

If a file format does not have a supported content extractor that extracts text then, optionally (default), a binary-to-text content extractor will be used to extract UTF-8, UTF-16, Windows-1252, and ASCII from the binary. In many cases, indexable text can be extract from unknown document formats.
